Galvanized steel pipe is a pipe that has a layer of zinc coating
placed onto its surface. The coating provides superior corrosion
protection to the pipe, with a corrosion resistance
measuring15times of an ordinary welded tube. Although some
galvanized pipes can be used for interior plumbing, the majority go
to the outdoor construction industry where the pipes are employed
to construct fences and handrails.
Galvanized steel pipe generally takes three forms:pre-galvanized, hot-dipped, cold-dipped. Pre-galvanized steel pipe is always referred to the pipe which is
made of galvanized steel coils and welded type.
The pipes which are given the galvanization treatment can becalled hot-dipped galvanized steel pipe or cold-dipped galvanized
steel pipe.Generally hot –dipped galvanized steel pipe is the best choice
among the three types due to the thick zinc coating.
Galvanized steel pipe is generally connected by threads on either
end of a length of pipe. A small amount of adhesive is typically
placed on the threads before screwing them together, in order to
reinforce the connection. If no threads are available, the pipes
and fittings can be welded together.
Galvanized steel pipe can beround tubular steel pipe, square hollow section pipe, rectangular
hollow section pipe, oval-shaped steel pipe etc.And mostly the price for seamless galvanized steel pipe is higher
than that of welded galvanized steel pipe.
