Through a long-standing partnership of over 20 years, Tremco Pipeline Equipment supplies 12 types of durable and hard-wearing Sawyer Manufacturing external pipe clamps to the Oceania pipeline market. Each is suited to specific applications, including small or large diameter pipe, alignment or reforming, tack or no tack, and clamps with hydraulic or hand lever mechanisms. But how do you know which external pipe clamp is the most suitable for your needs? 

To make the process easier, Tremco Pipeline Equipment and Sawyer Manufacturing have teamed up to explain the basics of pipe clamps, and demystify which clamps are best suited to specific applications. 

What is a pipe clamp? 

A pipe clamp is a circular or semicircular metal attachment that fits tightly around the pipeline and connects it to a pipe hanger assembly. The clamp is used to secure, align or reform the pipe while completing pipeline welding during construction or maintenance activities. 

How do pipe clamps work? 

The best pipe clamps are made with a simple structure that can be easily and quickly fitted around the pipe. For welding, pipe alignment clamps keep the pipe aligned and restrained while the welding process is completed. They help to keep welding pressure steady, increase welding accuracy, and reduce the risk of weld failure due to stress, misalignment or lack of pressure.

External clamps can also be used to reform pipe to aid accurate and efficient welding for out-of-round pipe. Also known as pipe ovality, this can occur during the transportation of new high-strength steel, thin-walled pipe, or on existing pipelines that have been subject to adverse weather conditions or buried for a long period of time. 

Types of pipe clamp 

There&#;s a large range of different external pipe clamps available for specific needs. At Tremco Pipeline Equipment, we supply Sawyer Manufacturing cage clamps, rim clamps, hydraulic clamps, and easy-to-use, efficient clamps for small diameter pipelines. Sawyer&#;s line of pipe-to-pipe fit-up equipment is simple, easy to use, durable and enables accurate welding. 

So which pipe clamp is best? Sawyer Manufacturing has put together this quick quiz to help you decide on the right pipe clamp for your job.

Which pipe clamps are the best?

When it comes to selecting the best pipe fixings for a job, there is no &#;one size fits all&#; solution. In fact, selecting the best fixings depends on each unique installation environment and application requirements.

What needs to be taken into account when selecting the best pipe clamp?

Temperature:

Temperature variations can cause pipes to expand and contract. If the correct fixings and clamps are not used to take into account the pipe movement due to temperature changes, the installation could fail and cause damage to the building.

Before you can select the right clamps to deal with thermal expansion, you first need to calculate the level of thermal expansion on the pipework.

Weight:

All pipe clamps have a maximum load bearing capacity, which means you need to select a clamp which is suitable for supporting the load required.

As an example, you may require special heavy duty pipe clamps with a high safe working load to ensure the pipes are secured properly. These can also help you achieve maximum bracket distances between clamps as they are able to take more force.

Materials:

Pipes made from different materials will react very differently in certain scenarios. For example, there are many different types of plastic pipe (PE, PVC, PA, PP etc). Each has a different temperature resistance, and different resistance levels to chemicals such as oils, greases, acids, chlorine etc. This can affect what type of clamp should be used. For example, plastic pipes should usually be secured with a lined metal clamp or plastic clamp. An unlined metal clamp can lead to corrosion if used on a plastic pipe.

Then there are different types of metal pipe &#; steel, iron, copper and so on. This can determine what kind of pipe clamp can be used, for example, stainless steel pipe clamps cannot be used to fix a copper pipe as the two metals will react. So a nylon coated or plastic clamp must be used.
