Detailed
Specification
ASTM A53/ API 5L ERW Pre-Galvanized Steel Pipe
A pre-galvanized pipe, also known as inline galvanized pipe or continuous galvanized pipe, is a type of pipe that is made of pre-galvanized coils and strips.
This material has been pre-coated with a layer of zinc before rolling into a pipe. This coat helps to protect the pipe from corrosion and also provides a barrier against weld seam corrosion. The thickness of zinc layer of pre galvanized pipe is 40-100 g/㎡.
Application for Pre-Galvanized Steel Tube
Pre-G.I round steel pipes are often used in construction and manufacturing applications where they are exposed to corrosive materials, including steel structures, building structures, guard rails, fences, metal furniture, solar structures, scaffolding and so on.

Production Process
The coating is applied before the pipe is welded, and the entire process is typically done in a factory setting.
First, the galvanized steel strip is cleaned and then a coat of zinc is applied. The strip is then passed through a series of rollers to form it into a pipe shape.
Next, the weld seam is created, and finally, the pipe undergoes a final spray coating of zinc. This coat helps to protect the weld seam from corrosion.
