The q345b welded pipe needs to be subjected to water pressure, bending, flattening and other experiments, and has certain requirements on the surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver to a fixed length (or multiple feet).

Galvanized cold drawn seamless tubing has strong corrosion resistance, strength and rigidity, and is widely used in gas, heating and water transportation pipelines.

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.
