Welded Steel Pipes ASTM A53 Schedule 40 Carbon galvanized Steel
Pipe
Galvanized steel pipe is a welded steel pipe with a hot-dip
galvanized or electro-galvanized layer on the surface. Galvanizing
can increase the corrosion resistance of steel pipes and prolong
the service life. Galvanized pipes have a wide range of uses. In
addition to being used as pipeline pipes for general low-pressure
fluids such as water, gas, etc., they are also used as oil well
pipes and oil pipes in the petroleum industry, especially in
offshore oil fields, oil heaters in chemical coking equipment, and
condensation cooling. Pipes for septic tank, coal distillation
washing oil exchanger, trestle pipe piles, supporting frame pipes
for mine tunnels, etc.

Galvanized steel pipe has the following production steps:
Black parts
inspection→hanging→degreasing→rinsing→pickling→cleaning→dipping
flux→hot air drying→hot-dip galvanizing→cooling→passivation and
rinsing→unloading→inspection, trimming→packaging, storage,
transportation .
Galvanized Steel Pipe Features:
1. Corrosion resistance: Galvanizing is an economic and effective
rust prevention method that is often used. About half of the
world's zinc output is used in this process. Not only does zinc
form a dense protective layer on the steel surface, but it also has
a cathodic protection effect. When the zinc coating is damaged, it
can still prevent the corrosion of the iron base material by
cathodic protection.
2. Good cold bending and welding performance: mainly used low
carbon steel grade, the requirements have good cold bending and
welding performance, as well as a certain stamping performance
3. Reflectivity: It has high reflectivity, making it a barrier
against heat
4, the coating toughness is strong, galvanized layer forms a
special metallurgical structure, this structure can withstand
mechanical damage in transport and use.
