Detalhes Produtos

Galvanized seamless steel pipe is a kind of steel pipe with a hollow section and no weld from beginning to end. It is galvanized to improve its corrosion resistance and wear resistance.

Strong corrosion resistance: The galvanized layer can effectively prevent the steel pipe from being oxidized, thereby extending the service life.

Good plasticity and toughness: Galvanized seamless steel pipe is easy to bend, cut, weld and other processing operations.

Excellent electrical and thermal conductivity: The presence of the galvanized layer makes the steel pipe perform well when conducting current and heat.

Beautiful appearance: galvanized seamless steel pipe has a bright appearance and is not easy to rust.

Cleaning of steel pipe: remove oil, rust and other impurities on the surface of the steel pipe to ensure that the surface of the steel pipe is clean and smooth.

Hot-dip galvanizing: The cleaned seamless steel pipe is transported to the hot-dip galvanizing equipment, and the liquid zinc coating is attached to the surface of the steel pipe by heating to form a zinc protective layer. Hot dip galvanizing is currently the most widely used galvanizing process, which can ensure uniform coverage of the steel pipe surface.

Cold working: After the hot-dip galvanizing is completed, the steel pipe is straightened, cut, stretched and other cold working treatments to ensure that the size and shape of the steel pipe meet the standard requirements.

Inspection and packaging: quality inspection of galvanized seamless steel pipes, including appearance quality, dimensional accuracy, galvanized layer thickness and other indicators, and packaging for transportation and storage.
