With the exploration and innovation of Bebon people, DEN gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel, and established our own Machining processing center in order to meet customer's diverse requirements.




ERW Steel Pipe SHINESTAR STEEL GROUP CO., LTD.

ERW steel pipe ERW steel pipe (3) ERW tube is “high frequency resistance welding steel tube”, and the common welding process is different, the weld line is from the base material of the steel belt body melted, the mechanical strength is better than the general welded.

API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no instant heat loss and it gets concentrated near the weld.

What is ERW steel pipe pipelinedubai

(ERW) Electric resistance welded pipe is manufactured by cold forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.

Differences between ERW Steel Pipe and HFW Steel Pipe

ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
