▇ ▍ Description

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 Only those small-scale, outdated equipment and small businesses with electric galvanized, of course, their prices are relatively cheap.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.

Galvanized Seamless Mechanical Properties

The mechanical properties of steel is to ensure that an important indicator of the steel end-use properties (mechanical properties), it depends on the chemical composition and heat treatment of steel. Steel standards, according to different requirements, the provisions of the tensile properties (tensile strength, yield strength or yield point elongation) and hardness, toughness, user requirements, high and low temperature performance.

Galvanized steel pipe maintains a wide range of benefits, suitable for use in highly corrosive environments. The semi-smooth, zinc finish of galvanized steel pipe provides a layer of protection that is not seen in other types of protective materials. The galvanized coating process protects the underlying steel from encountering corrosive elements that could deteriorate the steel and ultimately weaken its structural integrity. Main advantages of galvanized structural pipe include:

Protects against corrosion and rust
Increased structural longevity
Overall enhanced reliability
Affordable protection
Easy to inspect
Less repairs
Rugged toughness
Easier to maintain than standard painted pipes
Protected by advanced ASTM standardization

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
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.
