Other Component

Isolation joints are mainly used between gas transmission and distribution pipelines and gas pressure regulation, metering, storage and other equipment, and their main function is to isolate each section of gas transmission and distribution pipelines, equipment and pipelines, protect them from chemical corrosion, and extend the service life of pipelines and equipment.

The polarization probe is to assemble the reference electrode and the polarization test piece that simulates the damage point of the anti-corrosion layer, buried in the soil, and measure the electrical potential of the test fragment to judge the protection state of the pipeline. The polarization probe is divided into saturated copper sulfate reference polarization probe and zinc reference polarization probe.
