Pipe clamps

Function of a pipe clamp

Pipe clamps are used to attach pipes to load-bearing structures and pipe supports. A pipe clamp is primarily used in building services engineering, where it fulfils the function of a support. The pipe clamp, also known as a "bracket", consists of an upper part, a lower part, two screws and an insulating insert.

How and for what are pipe clamps used?

Pipe clamps are used for installations in sanitary, cooling and heating systems. When pipes need to be attached to structures, machines or other constructions, the pipe clamp forms the connecting piece between the structure and the pipe.

A hanger bolt or a rotary fix plug is screwed into a pre-drilled hole in the building structure. A pipe clamp is fixed to this and tightened with an open-end spanner. The pipe is then inserted into the open lower part of the pipe clamp and the upper part is fixed in place with two set screws.

What is a pipe clamp made of?

Pipe clamps are available in the following materials: stainless steel, aluminium, copper, plastic, zinc and zinc-plated steel. They are fitted with screws and nuts or with a hinged and clamping system.

What kind of pipe clamps are available?

There is a wide range of pipe clamps, such as Hinged pipe clamps, sliding pipe clamps, plastic pipe clamps, silicone pipe clamps, cold pipe clamps and normal pipe clamps.

Which pipe clamp for which pipe?

Pipes can be fixed to walls, ceilings and floors with articulated pipe clamps. Plastic pipe clamps are often used for waste water pipes and rainwater downpipes. Sliding pipe clamps have a sliding bearing for smooth and noiseless sliding. Thanks to their material, silicone pipe clamps are resistant to high temperatures and are therefore perfect for applications with hot water or steam pipes. Cold pipe clamps are suitable for reliably preventing condensation and for cold and chilled water pipes.

In the SFS eShop, you will also find standard pipe clamps for simple and secure pipe fastening.

What standards are there for pipe clamps?

There are the same standards for pipe clamps as there are for fastening elements for the most diverse and individual applications. The standard is specified in DIN and defines the pipe clamps according to fastening type, material, weight and shape as well as the resistance classes.

Why must a pipe clamp always have an insulating insert?

Pipe clamps must have an insulating insert due to their thermal load-bearing capacity, as this makes them more temperature-resistant. The temperature resistance of the pipe clamp is determined by the insulation insert in the medium temperature range.

Useful tips for handling pipe clamps

• Use suitable pipe clamps to ensure the load-bearing capacity
• Always install pipe clamps at a fixed holding point
• Attach the pipe clamp behind the pipe fitting
• Ensure the correct spacing for pipe clamps
• Observe the distance between the pipe clamp and the pipe bend
• Avoid sharp-edged pipe clamps due to possible risk of injury
• The pipe clamp should be able to rotate over the pipe
