DIN 17175 St45.8 Galvanized Steel Pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. DIN 17175 Galvanized Steel Pipe 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 cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. DIN 17175 Galvanized Steel Tube has the advantages of uniform coating, strong adhesion and long service life. The DIN 17175 Steel Pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so Galvanized Steel Pipe has strong corrosion resistance.

The galvanized steel pipes we produce include galvanized round steel pipes, Galvanized Square Steel Pipes and galvanized rectangular steel pipes, with high quality and good service, welcome to inquire.
The production process of galvanized steel tube is more complicated. In simple terms, it can be operated according to the following steps:
Pipe Cutting → Select Plate → Punching → Welding ↓
Packing ← Drying ← Galvanizing ← Welding Inspection
The uses of galvanized steel pipe are varied and can be roughly divided into:
1)Pipes for pipelines, water, gas pipes
2)Oil pipe suitable for oil industry, oil heater for chemical coking equipment
3)Steel Structure Engineering, Support Pipes for Mine Pits
4)Machinery Manufacturing and Chassis
