production processThe production process of longitudinal welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can be used to produce welded pipe with l

Galvanized steel pipe is a steel pipe that has been coated with a zinc layer. The zinc layer coating protects the steel pipe from corrosion and rust. The zinc layer provides a barrier against corrosion so that the pipe can be used in the outdoor environmental conditions with satisfied service life.
