API 5L PSL1 X52 ERW Galvanized Steel pipe use for water transmission
Hot-dip galvanizing has the advantages of uniform coating, strong
adhesion and long service life.
The dense zinc-iron alloy layer of the hot-dip galvanized steel
pipe is integrated with the pure zinc layer and the steel tube
base, which has strong corrosion resistance.
As long as the forming angle is changed, hot dip galvanized steel
tubes of various calibers can be produced from strip steel of the
same width.
Continuous bending and forming, the fixed length of the spiral tube
is not limited, and the length can be customized.
The spiral welds are evenly distributed on the circumference of the
spiral pipe, so the spiral pipe has high dimensional accuracy and
strong strength.
It is suitable for the production of small batches and multiple
varieties of spiral tubes. The welding seam of hot dip galvanized
pipe is longer than the welding seam of straight seam pipe of the
same specification. With the same wall thickness, the hot dip
galvanized pipe bears the greatest pressure.
Hot dip galvanized pipe
The molten metal is reacted with an iron matrix to produce an alloy
layer, thereby combining the substrate and the plating layer.
Hot-dip galvanizing is to pickle the steel pipe first, in order to
remove the iron oxide on the surface of the steel pipe, after
pickling, it is washed by ammonium chloride or zinc chloride
aqueous solution or a mixed aqueous solution of ammonium chloride
and zinc chloride, and then fed. Hot dip plating tank. Hot-dip
galvanizing has the advantages of uniform plating, strong adhesion
and long service life. Most of the northern processes use
galvanized strips to directly coil the zinc.
