Clamps for fastening water pipes, metal, steel

Installation of water supply, heating or sewage systems is carried out using a set of structural elements. These include metal steel pipe clamps for fixing water pipes. Although the process of transporting the working medium is carried out without their direct participation, they are also necessary, since they ensure the fixation of the pipeline having a certain orientation in space - vertical or horizontal.

Metal clamps come in different sizes and are used to fix pipes of any diameter

Main parameters and purpose

The clamp looks like a ring or staple covering a pipe. The diameter of this product may vary in the range of 14 ≤ D ≤ 540 millimeters. The clamp fits snugly to the surface of the pipeline due to the clamping mechanism included in its construction. A connecting nut that provides fixation to the plane is located on the outside of the plate. A plastic dowel with a self-tapping screw or a pin can be screwed into it. On sale you can find clamps equipped with elastic sealing gaskets.

Staples and rings are used for:

• increase in durability and reliability of fastening of pipe joints, especially in the case of a bell-shaped connection;
• fastening unstable and extended water, heating and sewer pipelines to the ceiling, walls or floor. Risers of water supply and sewerage are fixed without fail.

Metal clamps for water pipes have the following advantages:

• the possibility of using various types of pipelines for fastening;
• ease of installation;
• relatively low price.

The clamp is a very simple but reliable and durable construction.

As a rule, a layer of anticorrosion coating is applied to the product, which increases the service life and increases the aesthetic characteristics of the entire structure. The production of clamps is regulated by GOSTs. The standards indicate their main parameters:

• extreme loads maintained by fixture;
• boundary indicator of tightening;
• width and thickness of the tape;
• diameter;
• metal composition.

Good to know! Along with fasteners, plumbing repair clamps with rubber gaskets are also available. With their help, you can quickly block the flow in the branch of the water supply system without first shutting off the fluid flow and draining it.

Types of clamp mounts

The classification of metal steel clamps is carried out according to the following criteria:

• material;
• the form;
• appointment;
• gasket availability;
• type of fixation.

Clamps can have a different type of attachment to the surface and vary in purpose

Depending on the type of pipeline intended for installation, the clamps used for this may have various structural properties. Below are the main types of these products.

1. Spiral clamp. With its help, the reinforced parts of the water supply are connected. It can have a turn both clockwise and against it.
2. Power clamp. The purpose of this product is to connect reinforced hoses, flexible and rigid hoses, rectangular and round pipelines.The recommended field of application is the installation of systems operating under pressure: hydraulic pneumatic drives, pumps. The design of such a metal clamp for fastening pipes is a steel tape with a clamping component.
3. Reinforced fasteners. It is used for fixing pressure hoses with thick walls or with reinforcement.
4. Wire mount. Scope - fasteners of vibrating hoses and thin-walled spiral or corrugated pipes. Design - one or more steel rings, the pulling of which is carried out by a special mechanism.
5. Worm clamp. It is used for fixing pipes and hoses in places with a high level of vibration, as well as in heating systems and water supply systems. The design includes a metal strip on which there is a track with teeth and a bolt (screw) for tightening.
6. Pipe clamp. It is used to fix pipes of a certain section of engineering communications in an open way in order to fix its location. In addition, the use of such a part reduces the level of stress acting on the inside of the pipeline. Represents the connected two brackets or the cut ring with fixture.
7. Spring clamp The scope is the fixation of structures subject to thermal expansion. That is, it is relevant to use a steel spring clamp for fastening pipes for hot water supply and heating.

Main characteristics

Other criteria were mentioned above, on the basis of which such products are subdivided into certain types. Let's consider them in more detail.

Stainless steel fasteners are the most durable since they are not susceptible to corrosion

Material. As raw materials for the manufacture of metal products, galvanized and stainless steel are used. The simplest type of clamps for fastening stainless steel pipes are two-piece models. Galvanized parts are the same brackets made of cold rolled steel. They are used for mounting a branch of engineering communications on a horizontal plane or for fixing a hose.

Note! Pipe fasteners are implemented on the basis of denser materials reinforced with transverse nickel fibers.

Type of fixation. Fixation with a pipe clamp can be fixed (rigid) or movable. In the first case, the fastener is not able to move from its installation point. The brackets are tightly bolted together and attached to the wall, floor or ceiling. This method of fixation is used in places of branching, as well as bends of cold water supply systems. Fasteners are used that can ensure pipe static and withstand maximum loads.

Movable (floating) fixation is used for pipelines of hot water supply and heating, changing their geometric parameters under the influence of high temperature in the direction of increase. Clamps with movable fixation do not impede the passage of this process. They provide a small range of longitudinal displacement of the pipes. However, this technical solution does not allow lateral deviations from the axis.

The form. There are three main structural forms of metal steel clamps:

• split ring. It opens on the one hand, and on the other has a movable connection. Fixing the fasteners after installing it is carried out using a bolt;
• two half rings having the same size. They are connected together by studs or bolts;
• U-shaped bracket. It can be completely metal or rubberized inside.

On sale you can see dual pipe clamps. With their help, nearby pipelines are conveniently attached.

Gasket. There may be a microporous rubber gasket inside the steel clamp. Of the advantages of such products it is worth highlighting:

• when passing through the pipe of the working medium, the resulting vibrations are damped;
• noise level during pipeline operation is reduced;
• tightness of joints increases.

Rubber band clamp helps reduce noise during piping operation

Fasteners with gaskets provide a durable and reliable fit. They have only one minus - a higher cost.

The sizes of metal steel clamps for fastening pipes of the most popular types can be found in the table below.

Table 1

The “Clamp” column displays the range of diameters of pipelines, the fastening of which can be carried out using the appropriate clamp.

Differences of repair clamps from fixing

The differences between these details are displayed in the name and are determined by the purpose of their application. So, with the help of repair clamps, pipelines are not fixed, but a wide range of breakdowns is eliminated. In particular:

• longitudinal and transverse pipe cracks;
• fistulas on the surface of pipelines;
• defects in welded joints;
• needle holes;
• violation of the tightness of the bell joints.

Part used in pipe repair, in the simplest version, is similar in appearance to a ring made of a metal plate, at both ends of which bends are created. In these bends holes were drilled for screws tightened with nuts. A sealing rubber gasket is inserted into the inner cavity of the ring.

The repair clamp differs from the mounting structure and appearance

On a note! Such a gasket is usually made of corrugated cellular rubber. If it is tightly squeezed, it is able to completely block the leak.

Of the advantages of using repair clamps, experts distinguish:

• quick and easy installation;
• no need to drain the water from the system and block its flow;
• strength and durability of a collar;
• reasonable price for the repair part;
• affordable cost of repair work.

Installation sequence

The installation procedure is not difficult to name. But here it is very important to observe the distance between the clamps, that is, the fixing step. This approach eliminates the deflection of the pipeline elements. The interval depends on the purpose of the system and on the diameter of the pipes.

Cold water supply:

• Pipe Diameter D_tr <2 centimeters - a step of 0.8 meters;
• 2 ≤ D_tr<4 centimeters - - step 1.1 meters;
• 4 ≤ D_tr≤ 11 centimeters - pitch 1.6 meters.

Heating:

• Pipe Diameter D_tr <2 centimeters - step 65 centimeters;
• 2 ≤ D_tr<4 centimeters - - step 0.95 meters;
• 4 ≤ D_tr≤ 11 centimeters - a step of 1.85 meters.

Mounting clamps are located at equal distances, which are calculated depending on the type of line

Install in the following sequence:

• mark the fixing points on the surface provided for fixing the pipes;
• drill holes;
• insert the dowels into them, and then tighten the clamps with the help of self-tapping screws;
• if necessary, lay a rubber seal;
• pass the pipes through the open clamps;
• tighten fasteners with bolted connections.

When installing a hot water supply or heating system to ensure movable fixation, do not tighten the clamps too much.

And in conclusion, some information that will be useful to owners of suburban cottages or cottages. The parts in question are suitable for mounting and chimneys. Tact clamps are issued in various modifications. The maximum possible diameter for fixing the chimney pipe is 40 centimeters.

Without metal steel clamps, it is almost impossible to build reliable communication in a house. These mechanisms are inexpensive and easy to use. And the branch of the water supply system equipped with their help will last for many years.
