Galvanized pipe introduction:

Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines. Today, however, we have learned that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside.

Galvanized seamless pipe is divided into cold-plated steel seamless pipe and hot dip seamless pipe.

--Hot dip seamless pipe

The seamless pipe is to make the molten metal and iron substrate reaction, the alloy layer, so that the substrate and coating combination of both. Hot-dip galvanizing is the first steel pickling, in order to remove the steel pipe surface of iron oxide, pickling, aqueous solution of ammonium chloride or zinc chloride or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then send into the hot dip tank. Hot dip galvanized coating uniformity, strong adhesion, and long life.

--Cold-plated seamless pipe

Cold galvanized, electric-galvanized, galvanized the amount of small, only 10-50g/m2 of its own resistance to corrosion than hot dip galvanized pipe a lot of difference. Regular galvanized pipe manufacturers, in order to ensure the quality, most do not use electric-galvanized (cold-plated). Only those small-scale, outdated equipment and small businesses with electric galvanized, of course, their prices are relatively cheap. The Ministry of Construction has formally below, cold galvanized pipe to eliminate backward technology, the future not be allowed to cold galvanized pipe for water, gas pipes.

Application info:

Galvanized steel pipe is an excellent choice for many applications and processing techniques. Some common applications for galvanized steel pipe include: Plumbing, Construction, Hot and cold liquid transportation, Bollards, Exposed environments, Marine environments, Railings or Handrails, Fence Posts and Fencing, etc,With the proper protection galvanized pipe can also be sawed, torched, or welded. Galvanized structural pipe is ideal for numerous types of applications where corrosion resistance is required.
