Industrial stainless steel pipelines, characterized by corrosion resistance, high strength, and easy cleanability, are widely used in industrial fields such as chemical engineering, food, pharmaceuticals, and energy. They serve as core infrastructure for transporting corrosive media and high-purity fluids. Their installation must comply with strict standards to ensure the safe and stable operation of the system.

Before installation, it is necessary to determine the pipeline material (e.g., 304, 316L) and specifications based on working conditions, conduct on-site surveying and line marking, and check for scratches or rust on the surface of the pipe material, as well as the integrity of the sealing surfaces of fittings (elbows, flanges, valves). The installation phase takes welding as the core process, and argon arc welding is mostly used to ensure weld tightness and avoid impurity residue. Pipelines must be fixed with specialized supports to prevent displacement caused by thermal expansion and contraction; additionally, insulating gaskets should be placed between supports and pipelines to avoid electrochemical corrosion.

After installation, pipelines must undergo pressure testing and air tightness testing to identify leakage risks. At the same time, anti-corrosion treatment should be applied to the outer walls of the pipelines, and the inner walls should be passivated or polished as required. The entire process requires strict control of the construction environment—especially in the food and pharmaceutical fields, where dust-free and sterile requirements must be met—to ensure the pipeline system complies with industry safety and hygiene standards, providing reliable support for the efficient operation of industrial production.
