ERW steel pipes are manufactured by low-frequency or high-frequency resistance “resistance”. They are round pipes welded from steel plates with longitudinal welds.  Square and rectangular steel pipes are to directly extrude the produced welded tube into the desired shape.
Fire pipe is to use the produced ERW steel pipe for pipe end groove processing and epoxy powder coating, for carrying water or other liquid to connect firefighting equipment.

The Type of Welded Steel Pipe

According to the shape of the weld, it can be divided into a straight welded pipe and a spiral welded pipe.
Electric welded steel pipes are used in oil drilling and machinery manufacturing. The furnace welded pipe can be used as a water gas pipe, etc.
The large diameter straight seam welded pipe is used for high pressure oil and gas transportation, etc.
The spiral welded pipe is used for oil and gas transportation, pipe piles, piers and the like.
