Description

Technical Field

Due to internal defects in the weld processing, such as slag inclusions and pores, it is easy to cause pipeline leakage under high temperature, high pressure, strong corrosion and other conditions, leading to safety accidents. In particular, some pipelines (including long-distance oil and gas pipelines, petrochemical pipelines, and nuclear industry pipelines) are often used to transport gas, liquid or solid particles. Due to the complexity and particularity of the pipe seat weld, after a period of use, the pipe seat weld will have defects, causing pipeline damage and leakage, causing harm to the environment and human health.
