ERW Carbon Galvanized Steel Pipe

ERW Carbon Galvanized Steel Pipe

ERW Carbon Galvanized Steel Pipe undergoes degreasing, removal, phosphating, and drying prior to plating. The pre-galvanizing treatment allows the product to be easily galvanized and ensures uniform coating thickness, strong coating adhesion and improved corrosion resistance. Fully galvanized welded pipes are widely used in hot water, natural gas supply systems, agricultural greenhouse construction, steel construction and medium and low pressure piping systems.

Product description:

ERW Carbon Galvanized Steel Pipe undergoes degreasing, removal, phosphating, and drying prior to plating. The pre-galvanizing treatment allows the product to be easily galvanized and ensures uniform coating thickness, strong coating adhesion and improved corrosion resistance. Fully galvanized welded pipes are widely used in hot water, natural gas supply systems, agricultural greenhouse construction, steel construction and medium and low pressure piping systems. It is cold formed and welded into a tube using a high frequency induction welding process to form a stronger weld than the base material. ERW Carbon Galvanized Steel Pipe is a steel tube covered with a zinc protective coating that greatly reduces its tendency to corrode and prolong its service life. The ERW tube feeds the strip into a set of forming rolls consisting of horizontal and vertical rolls that are placed to gradually enter the tube from the flat strip and then pass the tube through the welding electrode. The ERW Carbon Galvanized Steel Pipe is then cut to the desired length by an automatic cutter. The tube is then subjected to a pressure test for any leaks.
