API 5L X60 LSAW Steel Pipe

UOE, COE, and JCOE are different manufacturing processes used for producing large-diameter LSAW steel pipes.  UOE (Uing and Oing Process): UOE is an abbreviation for Uing and Oing. In this process, a steel plate is first formed into a U shape (Uing) and then pressed and expanded to an O shape (Oing) using a mechanical or hydraulic press. The UOE process allows for the production of high-quality, longitudinally welded pipes with excellent dimensional accuracy and a wide range of sizes. UOE pipes are commonly used in oil and gas transmission pipelines. COE (Crescent Oing Process): COE, also known as the Crescent Oing process, involves forming a steel plate into a C shape and then expanding it to an O shape. This process is suitable for producing large-diameter pipes with thick walls. COE pipes are characterized by their strong resistance to axial loads and are commonly used in offshore and structural applications. JCOE (Jing, Cing, Oing, Expanding Process): JC…
