Fastening by installing a clamp is one of the most affordable and at the same time inexpensive ways fixing the pipe to the structure or support. With their help, it is easiest to achieve a strong and reliable fixation of the pipeline. To choose the right device, you need to know what options the market offers. Do you agree?
We will tell you what you should pay attention to when choosing pipe clamps. The article we presented describes in detail how to choose best option and how to install it. The technology is described in detail and recommendations are given, compliance with which will ensure perfect result.
According to the principle of fixation, the pipeline can be attached to the support either rigidly or freely.
The rigid rigid mount is designed for maximum loads. It is chosen when installing “cold” pipelines and strengthening them in places where there is a high risk of structural damage.
The floating type of fixation is used in sections of the pipe where there is a high probability of expansion of the structure under the influence of temperature fluctuations
To fasten elements subject to thermal expansion, devices with floating mounts are chosen. They give the structure minimal mobility in the axis direction.
Fixing the pipeline with a clamp is achieved by tightening the pipe body with fasteners, the role of which is performed by locks, threaded pairs or worm mechanisms.
Regardless of the type of fixation, the use of clamps makes it possible to relieve the pipeline, thereby reducing the likelihood of damage to its individual sections under the weight of its own weight and vibration flows arising during movement.

Accidents in plumbing and heating systems, although common, are always unexpected and unpleasant. The good news is that minor damage can usually be repaired. on our own. For this it would be good to have a few clamps in stock the right size. They will help close a corrosion crack, block an “extra tap” or connect a broken section of a pipeline. Our article will tell you how to make a pipe clamp in one case or another.
Scope of application of clamps
Repairs can only be made on straight sections of the pipeline
The scope of application of such devices concerns only horizontal and vertical sections of highways. It is impossible to place a clamp on a pipe with a branch or at the junction where tees and crosses are located.
But these special parts are successfully used on structures made of different materials. You can equally well tidy up a fragile cast iron pipe and a flexible copper pipeline. The assortment also includes special clamps, intended for asbestos-cement pipes. You can also buy parts for open sale that are used in the repair of polymer and composite (metal-plastic) pipelines.
Repair devices of this type allow you to eliminate the following defects:
- Cracks in the body of highways. Their size can be very small or quite large (in length and width).
- Pipe fractures. To eliminate them, use a repair clamp with fastening. It not only helps to “heal” the structure, but also allows you to securely fasten the “break” to a support - a ceiling or wall.
- Fistulas in straight areas. In this case, the clamp on the pipe to eliminate the leak must have an elastic backing that is pressed into the fistula. For systems that transport aggressive chemical substances, special stainless steel repair parts are used.
- Damage caused by corrosion.
Types of devices
Industrial Clamps
Repair clamps industrial production have the following varieties:
- Repair double-sided. It consists of two “halves” connected by screws. This repair kit should be selected taking into account specific diameter pipes.
- Unilateral U shape. Used on small diameter pipelines ( maximum size- DN 50). The upper part of the element is perforated for threaded mounting.
- Multi-component. Designed to protect pipelines large diameter. Pipe clamp 6000 includes three or more elements. Accordingly, when installing such devices, at least three threaded pairs are used (one for each joint between the elements).
- For fastening pipes. In this embodiment, the repair kit can be single-sided or double-sided. At the bottom, a self-tapping screw is attached to it, passed through a special perforation. When assembling such a clamp, first of all, attach it to the wall bottom part. This is done using a self-tapping screw. Then they put the pipe into the lower connector, after which they press it top part devices.
Homemade clamps
Single-sided and double-sided clamps
Sometimes it becomes necessary to make homemade repair kits. In this case, you can use a rubber band, wire and tape. In practice it should go like this:
- A rubber band should be wound around the pipe (a rectangular piece of an old bicycle inner tube may be suitable for this purpose).
- After this, it must be tied with wire. The winding is done especially carefully around the edges homemade device- here it should be tightened with thick coils, laid side by side.
- Then the rubber fixed with wire is wrapped insulating tape or tape.
- At the end, it is recommended to paint the homemade clamp on the heating pipe.
Application of repair parts
Limitations on the use of clamps
As already mentioned, such devices can only be used on straight sections of networks and installed only on outside pipes. In addition, there are other restrictions:
- The pipeline being repaired should not have a diameter of more than 350 mm. This is why it is so difficult to find clamps for sewer pipes large size.
- The dimensions of the products should be within 15-20 cm plus the length of the damaged area. During repairs polymer pipes this excess is 20-30 cm.
- When a line ruptures, it can be repaired provided that the distance between the torn ends does not exceed 1 cm. The deviation of their axes should not be more than 2-3 degrees.
- Damage that can be closed with a clamp should not cover more than 60% of the pipe body. Otherwise, the section is simply cut out and replaced with a tap-in using fittings or two clamps.
Advantages of the part
Part for fastening pipes with self-tapping screw
If you use these universal parts, you will be able to appreciate its advantages:
- The repair kit is installed very quickly, literally in a few minutes. To fix it, you just need to screw in two pairs of bolt nuts.
- If you install the factory clamp correctly, it can withstand a heavy load - within 6-10 atmospheres. Moreover, the temperature of the transported substance in the system can reach 120 °C.
- Products have a wide range of sizes. The smallest clamp is designed for a 1/2 inch (150 mm) pipe, and the largest one can repair a pipeline that has a diameter of 1200 mm. True, in stores building materials you can only find serial products with a diameter of 350 mm. Larger items will need to be made to order.
- Having restored the integrity of the pipeline using a clamp, you can take your time to remove it. From experience, such “repairs” can last at least 5 years.
- The devices allow you to produce renovation work in the existing transport system. This is why clamps are highly respected by emergency plumbers.
Clamp-based repair kits are produced all over the world. However, experts most value such manufacturers as Romacon (Holland), Melcher and Frenzen Armaturen (Germany), Domex (Poland), IDRA (China).
If the question of how to install a clamp on a pipe is very difficult for you, you should contact a specialist. They will do it with ease. Let everything work smoothly and trouble-free in your home!
A clamp is a crimping material for pipelines. First of all, you should familiarize yourself with what types of clamps are available and for what purposes they are used. In this case, you can purchase a ready-made hose clamp in a store or make the device yourself. Manufacturing is quite simple and will help out in an emergency.
Pipes of large and small diameters have a bandage in their design - a special crimping material. It is made of steel and an internal seal called a cuff. The seal is corrugated rubber. It guarantees a seal and prevents deformation of the pipes if the fastening screws are tightly tightened. Rubber also reduces vibration and noise.
Important characteristics of clamps when purchasing:
- Diameter of the inner part;
- Width of crimping material;
- Bandage thickness.
The tightening force of the clamp depends on its size. The purpose of using the element depends on the strength of the connection. It is also important to consider the level of possible load.
The design of metal clamps is quite simple. The element consists of a steel crimp and a rubber seal.
Clamps are widely used to fix leaks in water pipes. In case of unexpected breakdowns, you can make the connection element yourself. Factory options have a wide range of uses: heating, gas, water, sewer pipes.
Types of pipe clamps to eliminate leaks
The popularity of clamps is due to a large list of advantages. These include versatility of use: suitable for both plastic and metal pipes, for plumbing and heating. Repairs using a bandage are quite easy. An emergency clamp is selected to eliminate the leak, taking into account the damage and the material used to make the pipes.
Types of clamps:
- Double-sided bandage. It has two elements in its design. Refers to universal devices.
- One-sided clamp. It is a product in the shape of the letter U. The design has a rubber gasket. Used for small pipes.
- Standard crimp option.
- Tripartite variety. Widely used for large cross-section pipes.
In addition to repair clamps, there is also a bandage for attaching pipes to surfaces. It looks like a regular bandage with a hole for a nut to attach the product to the floor or wall. Clamps are also distinguished by the material they are made of.
Banding devices are made from steel, cast iron, stainless steel and galvanized material.
Some manufacturers produce entire sets for bandages. This way you can repair large diameter pipes. The number of components depends on the cross-section of the pipes.
Making a clamp with your own hands from scrap materials
For work you will need a strip of galvanized sheet. The thickness of the steel should not exceed 1 mm. You will also need a piece of rubber 3 mm thick. In addition, you will need bolts, nuts and washers of suitable dimensions.
Necessary tools for work:
- Scissors for cutting metal;
- Hammer;
- Pliers;
- Wrench;
- Drill;
- Calipers.
Vernier calipers are used to determine the cross-section of pipes. For large pipes use a corner and a ruler. Next you will have to cut out the steel strip. Its width ranges from 4 to 8 cm. The length of the material is calculated separately. To do this, the circumference of the pipe is multiplied by Pi. You will have to add a few centimeters, taking into account the equipment of the ears.
The dimensions of the holes in the lugs depend on the cross-section of the bolts. With wide washers you should add an extra couple of millimeters. This will help you install the clamp later.
If the width of the crimp strip is more than 6 cm, then holes should be made for 3 bolts. The ears should be folded in a straight line. For convenience, measure the line with a marker. You can bend the line yourself or use pliers.
After this, the steel must be bent around the pipe. The ears are connected so that the holes coincide for screwing in the bolts. Then a pre-prepared rubber gasket is inserted.
Basic rules on how to install a clamp on a heating pipe
A bandage clamp is used when fistulas have occurred in the pipe. This occurs when metal walls are exposed to corrosion. Clamps are also used when cracks, fractures, or leaks occur in the water pipeline.
Bandage installation sequence:
- First, turn off the water supply. It acts as a coolant in the heating system.
- The installation site is cleaned and leveled. Removable with sandpaper upper layer paints.
- Next, install the clamp. The nuts are loosened a little to position the part correctly. The rubber seal should be placed in the middle of the break.
- All that remains is to tighten the clamp. Keys are used for this.
At correct installation There shouldn't be any leakage problems. When the water supply is restored, the effect is immediately noticeable. To improve the tightness of the device, the surface of the silicone strip is treated with a silicone-based sealant. After polymerization, the connection will be more reliable.
The cost of a clamp can vary significantly. Not only the manufacturer plays a role, but the material and complexity of the design.
To save money, you can use homemade clamps. But irregular shape devices are fundamentally unsuitable for sewer pipes. They can only lead to more severe damage. Therefore, in such cases it is better not to take risks.
A quality product can last long years. But if the pipes are old enough, problems may arise elsewhere. That is why it is recommended to replace the old pipeline. At high blood pressure In pipes it would be better to use welding. This is a more secure mount.
Except standard options mortise clamps are distinguished. They are used when connecting a house to a central water supply. Installation of such devices is carried out by mechanics using milling machine. But this option of work is available only to professionals.
Types of pipe clamps (video)
The design of the clamps is quite simple, as is the installation. That is why, if necessary, you can create a clamp with your own hands. The clamp can even be made from wire. But it is better to use a small piece of metal and rubber. The main thing is to adhere to the installation rules, and then the leak will be reliably eliminated.
Communications are perhaps the most problematic area in modern apartments and houses. Even a carefully assembled and adjusted system can fail over time, which manifests itself in the form of a small leak or outright fountains from the pipe, if the problems are serious. In both cases, a plumbing pipe clamp is best suited as an immediate solution to the problem, which makes it possible to quickly resolve the difficulties that have arisen.
Clamps allow you to quickly repair critical holes in pipes or install communications to walls and ceilings. Their design is as simple as possible - if the installation technology is followed, the mount is guaranteed to serve you for several years. This article will provide you with detailed instructions about how to install a clamp on a pipe with your own hands.
Installation of clamps
Material selection
Clamps come in various sizes and designs, but all types have a spherical shape that follows the bend of the pipe. The design of the product necessarily contains clamping bolts, which make it possible to tighten the clamp as tightly as possible around the pipe being repaired/installed. According to the scope of application, these products are divided into fastening and repair items.
The clamp fastener consists of a metal shell and a corrugated rubber gasket, which prevents noise from vibration and excessive compression when tightening. Required condition Products of this type include the presence of a side fastening, which is most often made in the form of a welded nut - with its help, the pipe is mounted/suspended on a wall or ceiling.
Leak repair clamps have a wider metal shell and a solid rubber gasket that... There are also specialized products for inserting an additional branch into the water supply system - with its help you can create a branch without participation welding machine. The only condition for its use is the absence of strong pressure in the system.
Upon purchase, Special attention You should pay attention to the sizes of plumbing pipe clamps - an incorrectly selected size will make the purchase in vain. The diameter of the pipe is determined by a caliper or, in the absence of one, you can simply measure the external cross-section of the pipe.
The presence of a rubber gasket is also important - it is not always included in the basic package. If there is a choice between products with and without a seal, then you should give preference to the first option, even if its price turns out to be an order of magnitude higher - the gasket significantly increases specifications fastenings
Installation of fasteners
- The path of the future pipeline is marked, the location of the fastenings is noted. The distance between the fasteners is determined depending on the length and weight of the pipe - in standard situations it is about one to two meters;
- At the site of future fastening, a hole is drilled into which a plastic dowel is inserted, and a threaded pin at the end. The clamp is screwed onto the pin in the open state - you should screw it all the way, but you should not be too zealous so as not to deform the shell of the product;
- The pipe is inserted and the clamp is clamped. It is important here to create a floating clamp and not to overdo it - it should not be too tight to compensate for the thermal expansion/contraction of the material;
Note!
In this case, this means installation of ventilation, chimney and other light items - heavy large-sized metal pipes, filled with water cannot be secured in this way.
- Before placing the clamp on the pipe, it is advisable to turn off the water supply to the system. If this is not possible, installation is also possible, but you will have to get pretty wet;
- The clamp is placed over the broken area so that the crack/cavity is located approximately in the middle of the rubber gasket. The rubber seal should lie flat, without wrinkles. The fasteners are tightened as tightly as possible to avoid leakage;
- The connection point is wiped dry, the supply is resumed and inspected for leaks. If this occurs, then the fastening is additionally tightened;
Pipe tapping
First of all, a hole of the required diameter is drilled, then an adapter is put on it. The main thing is that the sealing gasket fits without bending. After tightening the clamps, the connection is ready for installation of an additional water supply branch.
Note!
During operation. Pressure should not be applied to this type of connection as this may cause leakage or deformation of the clamp.
At the first signs of depressurization of the pipeline, it is necessary to quickly find the damaged area and eliminate the identified defect. When performing emergency emergency work You can use homemade clamps to stop the flow in the pipeline for a while. Ready-made clamps for fastening pipes, made in the factory from stainless steel or fire-resistant plastic, are used when performing installation work on the installation of heating, sewerage, water supply, gas supply systems. These fasteners allow you to reliably fix the position of pipes running along horizontal and vertical surfaces (ceilings, walls), as well as those installed on special racks.
In this video experienced master shows how to make a wire clamp:
Design of a simple clamp
Without exception, all pipe clamps consist of a bandage - a crimping material made by manufacturers from steel, and an internal seal called a cuff. As a sealing material that ensures sealing of the damaged area, special corrugated rubber is usually used, which helps prevent deformation of the pipe when the fastening screws are tightly tightened. The presence of a rubber gasket in the design of the product also helps reduce vibration and noise.
When choosing clamps, pay attention to such product characteristics as:
- inner diameter;
- bandage width;
- thickness of the steel strip.
The tightening range of the clamp varies depending on the size of the fastener. The main indicators that determine the scope of its application are the strength of the connection and the level of permissible load.
Metal clamps for fastening and repairing pipes different diameters consist of a steel frame and a seal made of corrugated rubber
Making a clamp from scrap materials
Find a strip of galvanized sheet metal, the thickness of which does not exceed one millimeter, and a piece of three-millimeter rubber. Look in your supplies for a couple of bolts (M6, M8 or M10), as well as matching nuts and washers. Tools that will be useful:
- hammer;
- calipers;
- spanners;
- vice or pliers;
- metal scissors, which can be replaced, if available, with a jigsaw or grinder equipped with appropriate cutting elements;
- drill and drill bits (M7, M9 or M10, M12).
Use a caliper to determine the pipe diameter. If the pipe diameter is large, then take the necessary measurements using an angle and a ruler. Next, cut out the tin frame of the clamp in the form of a strip, the width of which should be 4-8 cm, and the length will have to be calculated. To do this, determine the circumference of the pipe by multiplying its diameter by 3.14 (the number Pi, familiar to everyone with school course geometry). Add 3-4 cm to the result obtained, from which “ears” are subsequently made with drilled holes for fastening bolts.
The size of the holes in the “ears” depends on the diameter of the bolts, and if the washers are wide, then you can add an extra 2-3 mm to simplify the installation of the clamp in the future. If the width of the bandage exceeds 6 cm, then it is recommended to drill holes not for two bolts, but for three. Mark with a marker a line along which to bend the “ears” at a right angle to the tin strip. This operation can be done manually if the strip is thin. Thicker material is worked with a vice or pliers.
Next, the tin is bent around the pipe on which it is planned to put the clamp, and they try to connect the ears so that the holes drilled in them coincide. If the tin does not bend well, then tap the strip with a hammer. A pre-cut rubber gasket, cut to fit the width of the bandage, is inserted into the clamp.
Algorithm for installing a clamp on a pipe
Before installing the clamp, the ears are moved apart so that they can easily wrap around the pipe. In this case, the rubber gasket should well cover the area of the pipe defect. If everything was measured correctly, then there should be no more than three centimeters between the ears. This distance will necessarily decrease as the clamp is tightened with bolts, and this process continues until the rubber seal can be pressed as tightly as possible to the pipe.
Clamp for eliminating leaks in a water pipe or heating system At home, it can be installed at the site of damage with your own hands within a few minutes.
In most cases, clamps are installed on a leaking pipe. Shutting off the supply of water, coolant or Wastewater is not produced. Therefore, the effectiveness of the repairs performed will be immediately visible. After wiping the pipe and bandage dry, wait about five minutes and make sure that the leak has been fixed. If necessary, bolts that are too long can be easily cut with a grinder or a hacksaw.
A properly installed clamp can last for several years, protecting the facility from flooding. However, it is advisable to weld breaks in water supply and heating systems or replace defective areas with new pipes.
Insertion into the main water supply
When connecting the water supply of a private house to central system water supply, a mortise pipe clamp is used, which allows work to be carried out under pressure in a short time using a specialized professional equipment. A clamp for tapping into a pipe without pressure is installed by a simple mechanic using a cutter and a pair wrenches. This does not involve the use of a welding machine. In any case, this work is carried out by employees of services servicing the main water supply system in locality, provided the client has all permits.
Stages of installing a mortise pipe clamp in a main pipeline. Clamps for inserting into pipes simplify work on connecting the facility to central water supply systems
Now you know how to make and install a clamp on water pipe. If the pipeline is damaged, you will be able to fix the problem yourself, at least for a while before professional plumbers arrive.
