LSAW Welded Steel Pipe Features and Manufacturing Process

LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.

LSAW Steel Pipe, Longitudinal Submerged Arc Welded

LSAW Pipe stands for Longitudinally Submerged Arc Welding pipe. Pipes manufactured by this process are subjected to expanding operation in order to relieve internal stresses and obtain a perfect dimensional tolerance. Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service,

What are the Characteristics of LSAW and Permanent Steel

Since the rolling direction of the spiral welded coil is not the direction of the vertical steel pipe axis (the pinching depends on the helix angle of the steel pipe), and the rolling direction of the straight seam welded steel plate is perpendicular to the axial direction of the steel pipe, the crack resistance of the spiral welded material Better than straight seam welding.

The Difference Between Welded Pipe and Seamless Pipe

Seamless pipe is divided into hot rolled seamless pipe and cold drawn seamless pipe,hot rolled seamless pipe is producing through the billet forging, punching, rolling, shaping and other processes.It is widely used to produce large diameter and thick walled seamless pipe,cold drawn pipe is formed in cold drawn process,the strength of materials is relatively low, the surface is more smooth.The small diameter and
