How to groove galvanized steel pipe

Galvanized steel pipe is a kind of pipe based on welded pipe and plated with a layer of zinc to prevent rust and corrosion, which is widely used in water supply and drainage, gas, steam and others. Today, let‘s talk about how to groove galvanized steel pipe.

1. Quality requirements for galvanized steel pipes


Since the grooved fittings are engaged with the outer wall of the pipe, the deviation of the pipe OD will make the pipe and the coupling unmatched, which will cause water leaking . In addition, unqualified material, unstable galvanized layer, insufficient wall thickness, may cause pipe broken, the zinc coating falling off or the high-frequency weld cracking, which eventually leads to water seepage or fracture of the joint. Therefore, it is very important to strictly control the quality of pipes.
