The role of insulation joints and installation specifications

Insulated joints are actually the collective names of pipe joints with insulating properties. The range of applications for insulated joints is very wide. They are generally applied between pipe sections with different anti-corrosion layers, pipe connections at branch lines, pipe sections affected by AC or DC interference, pipe sections with different electrolytes, etc. .

Insulation joints include cemented insulation joints, rail insulation joints, pipe insulation joints, female pre-insulated joints, etc. These insulation joints can insulate and isolate the sections of the gas transmission and distribution pipeline from each other and protect the equipment from pipelines from chemical corrosion. , to extend the service life of pipelines and equipment. When installing insulated joints, please note the following points:

1. Insulation joint installation place within 50 meters, to avoid welding dead mouth

2. Do not lift the pipeline within 5 meters of the joint after the insulation joint is connected to the pipeline

3. Insulation joint and pipeline instrument pressure test

If the insulation joints are not properly installed, it may not only fail to protect them, but will reduce the service life of the equipment and impede its normal operation.
