Hot-dip Galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery,
prospecting machinery and other manufacturing industries. Galvanized Steel Pipe Welded steel pipe with hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. Galvanized pipes have a wide range of uses. In addition to line pipes for conveying water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil pipes in the petroleum industry, especially offshore oilfields, as well as oil heaters and condensate for chemical coking equipment. Pipes for coolers, coal-distilled wash oil exchangers, pipe piles for trestle bridges, pipes for support frames in mine tunnels, etc. Production steps of galvanized steel pipe:
a, round steel preparation; → b, heating; → c, hot-rolled piercing; → d, cutting head;→ e, pickling; → f, grinding; → g, lubrication; → h, cold rolling processing; → i , Degreasing; →j, solution heat treatment; →k,straightening; →l, pipe cutting; →m, pickling; →n, finished product inspection.
