ASTM A35 ERW Steel Tube

Product Description

ASTM Cold Rolled Black Annealing High Frequency Resistance Square Round ERW Steel Tube For Energy


High frequency straight seam (ERW) according to the welding process is divided into different induction welding and resistance welding two forms, based on hot rolled wide volume as raw material, through the continuous forming, bending, welding, heat treatment, sizing, straightening, cutting process, such as media compared with the spiral seam is short, high dimensional accuracy, uniform wall thickness, good surface quality, high pressure, but the drawback is that only production of small diameter thin The wall pipe and weld are prone to gray spots, unfused and furrow corrosion defects. At present, it is widely used in urban gas and crude oil transportation.


What is the difference between ERW and ordinary welded pipe?


1. Welded pipe refers to the common "submerged arc welded steel pipe", which is represented by "SC" in electrical engineering. It can be used as water and gas pipe or threading pipe, which is relatively thick.


2. Pipeline pipe, that is, wire pipe, is relatively thin and is represented by "T", which can only be used for threading.


3. ERW pipe is a "high-frequency resistance welded steel pipe". The welding process is different from that of ordinary welded pipe.


The biggest difference between ERW steel pipe and seamless steel pipe is that ERW has a weld, which is also the key to the quality of ERW steel pipe.
