The difference between welded pipe and galvanized pipe is mainly in three aspects: definition, classification and use.

The cs seamless pipe will use the pickling step during processing. After the pickling, it usually needs to be washed with water,so what are the problems that need to be paid attention to when the cs seamless pipe is washed with water?

Cold drawn seamless tubing are widely used in the production of various structural parts, tools and mechanical parts. Compared with round pipes, cold drawn seamless tubing generally have larger moment of inertia and section modulus, have larger torsional resistance, save materials, and can be used directly in factories or machining plants without deep processing.

The production process of galvanized pipe is to first pickle the steel pipe to remove iron oxide and impurities on the surface of the steel pipe. It is cleaned and sent to a hot dip aqueduct.

The raw material of black steel seamless pipe is iron, which will rust after a long time, affecting the service life in the pipeline and causing unnecessary losses. Therefore, the anti-corrosion of black steel seamless pipe is a process that must be done before pipeline construction.

The stainless steel welding methods used in industry mainly include tungsten argon arc welding (TIG), high frequency welding, plasma welding and laser welding.
