Seamless steel pipe owns three unique advantages, namely high pressure endurance, great strength and uniformity of structure.

Seamless steel pipe is most favored by its high pressure endurance. Normally, the weakest part of pipes is the welding line, but seamless pipe doesn’t have a seam, so the entire circumference of the pipe can evenly withstand high pressure. Besides, owing to the lack of the welding line, seamless steel pipe is able to support its own weight as well the heavy loaded weight, and maintain its original structure. There advantages bring seamless steel pipe a number of commercial applications, not only in oil field, but also in ship building, offshore rigs, pressure vessel and so on.

As for ERW steel 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 steel 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. Besides, owing to the almost clean and smooth surface, ERW steel pipes are easy to be applies with coating method.
