Oil, Gas & Chemical
Welding is the main link in the construction of petrochemical engineering, which directly affects the performance of equipment and system safety. There are various types of welding structures for petrochemical equipment, and the operating conditions are also different. The working medium generally has characteristics such as high temperature, high pressure, flammability, explosiveness, deep cooling, corrosion, etc., which puts forward high requirements for equipment steel and welding processes. Meanwhile, common petrochemical equipment, such as spherical tanks, storage tanks, process pipelines, and transportation pipelines, generally have a large scale. They not only have high requirements for safe operation, but also are mainly installed and welded on site, especially for large equipment and structural components. The technical requirements and difficulty of manual welding are particularly prominent.
