How to avoid thermal expansion and thermal deformation of carbon steel pipes at high temperatures?

Carbon steel pipes are prone to thermal expansion and thermal deformation at high temperatures, which can lead to leaks at pipe connections or damage to the pipe itself. Here are a few ways to avoid this:

1. Choose the right pipe support
Proper pipe support can help the pipe bear the weight and limit thermal expansion and deformation. Proper selection and installation of pipe supports can reduce pipe deformation and twisting.

2. Use expansion joints

An expansion joint is a device specially designed for thermal expansion of pipes. Since the expansion joints can expand and contract freely, it reduces the stress on the pipe joints, thus avoiding leakage or damage.

3. Use a compensator
A compensator is a device used to adjust the length of a pipe and account for thermal expansion. It flexes to compensate for changes in pipe length while reducing stress on pipe connections, preventing leaks or damage.

4. Reserve enough expansion and bending space when designing the pipeline
When designing the pipeline, the thermal expansion and thermal deformation of the pipeline at high temperature should be considered, enough space for expansion and bending should be reserved to accommodate the change of pipeline length, and excessive stress should be avoided at the pipeline connection.

5. Control pipeline temperature
Controlling the temperature of the pipe can reduce the thermal expansion and thermal deformation of the pipe at high temperature. The temperature of the pipeline can be lowered by cooling water or other means, or the temperature of the pipeline can be increased by equipment such as a heater to control the temperature of the pipeline.

The above are some methods to avoid thermal expansion and thermal deformation of carbon steel pipes at high temperatures. It is necessary to choose the appropriate method according to the specific situation to ensure the safe operation of the pipeline.

Tips: Carbon steel welded pipes can be divided into three types: straight seam submerged arc welded steel pipes, spiral welded pipes, and high-frequency straight seam welded steel pipes （Electric Resistance Welded Steel Pipe) according to the forming method of the weld seam.
