Everything You Need to Know About Pipe Clamp

About Pipe Clamp

A pipe clamp is best defined as the support mechanism for suspended pipes. It ensures that all pipes are firmly sealed, while also enabling any future pipe movement or expansion. Pipe clamp comes in many variations as the pipe fixing specifications can vary from basic anchoring to more complicated pipe movement scenarios or heavy loads.

Types of pipe clamp:

  • Plastic Pipe Clamp

The plastic pipe clamp is used mainly on plastic pipes or in domestic copper pipes. These are suitable for light loads and pipes smaller in diameter. They’re also perfect for jobs which require lots of clamps due to their quick installation time.

  • Traditional Pipe Clamp

Traditional pipe clamp includes U Bolts and Saddle Clamps, which are most widely used for holding steel or copper pipes. Traditional pipe clamp does not have an internal lining, so they are best suited for pipes where there are no external variables to consider, such as temperature or noise insulation.

  • Heavy Duty Pipe Clamp

A heavy-duty pipe clamp is designed for use where heavy load support is needed. They can be used outdoors and indoors, with or without padding.

Technical Data

One of the first major decisions you’ll come up against in any well-planned use of pipe clamp for securing conduit or cables is what size or diameter to use for which type of application. This is particularly important in plumbing applications, where different specific grades of pipework are needed to handle different supply lines or drainage outlets.

  • 10 mm Pipe Clamp

10 mm pipe clamp is used to protect the smaller ductwork and central heating systems, typically in copper, brass, or, perhaps, in much older houses. Due to reduced heat loss through smaller pipes, microbore systems may give some real efficiency advantages. Still, the trade-off has a greater tendency to clog, particularly in hard water areas.

  • 20 mm Pipe Clamp

A 20 mm pipe clamp is ideal for a range of applications. It is often used either as water main above ground (provided it is a suitably hard-wearing and UV-resistant material such as MDPE) or as a surface irrigation pipe. It is also used in various applications for electrical cabling, trunking, and routing, typically by PVC tubes or similar high-grade plastics.

  • 28 mm Pipe Clamp

In most household plumbing applications, the 28 mm pipe clamp is generally regarded as the largest ordinary grade of water supply conduit.

  • 32 mm Pipe Clamp

The best way to secure moderate-flow waste pipes from basins, bidets, and other medium-sized appliances is to use a 32 mm pipe clamp. Up to three such fixtures can, in most cases, be fed into a single 32 mm waste pipe, provided the run is not too long. Products are usually plastic or identical to uPVC.

  • 40 mm Pipe Clamp

40 mm is a typical pipe clamp diameter used to support treated plastics (uPVC or similar) or stainless steel wastewater systems. This tubing grade and 40 mm pipe clamp is frequently seen, bringing a higher volume of waste from the baths and showers.


There’s no one size fits all approach when it comes to choosing the right pipe fittings for a task. In reality, it depends on each specific deployment environment and application specifications to select the best fixings.

Things you need to consider when installing pipe clamp

  • Temperature

Variations in temperature can cause the pipes to expand and contract. If due to temperature changes, the appropriate fittings and clamps are not used to accommodate the pipe movement, the installation may fail and cause damage to the building. You first need to measure the thermal expansion level on the pipework before you can select the right pipe clamp to manage thermal expansion.

  • Size

The size of the pipe will affect the type of pipe clamp that you need, as all clamps are available only in certain minimum and maximum diameters. Single screw clamps, for example, often have a more restricted size range because they need to hinge open on one side.

  • Weight

All pipe clamps have maximum load-bearing power, meaning you need to choose a pipe clamp that is appropriate to accommodate the necessary load.

  • Other Requirements

Some construction projects may have specific requirements such as noise insulation or need for quick installation. There are special clamps which can be used in such situations.

For example, if the necessity is to mount the pipe clamps as quickly as possible, it would be easier to have a one-screw clamp. Pipe clamp with rubber lining provides soundproofing for the noise insulation. Many of the pipe clamps at Fischer have approved sound insulation standards.
