ERW Tubing

ERW (electric resistancewelded) tubing is designed to deliver the oil and gas to the ground from well bottom. It is manufactured by rolling steeland then welding it longitudinally across its length. Both ends of ERW tubing are threaded to facilitateconnections, and guard ring is used to protect the thread of tubing and joint.

ERW tubing comes in two types, that is, non-upset tubing(NU) and externalupset tubing(EU).
