Pipe Manufacturing Process / Methods for Seamless & Welded ...

As for ERW pipe, one of the biggest benefits is that only the tube billet ends are heated during the manufacturing process, therefore the rest of the whole ERW pipe remains clean and only the welding part needs to be cleaned. This reduces the post-welding cleaning work, largely increasing the working efficiency and saving cost.
