HAEUSLER AG - LSAW pipe roll bending machine RMS
To allow bending of high wall thicknesses to small diameters (< 508 mm diameter at 12.2 m tube length) the top roll can be pre-loaded. For very small diameters a supported top roll can be used. This machine offers you an optimum balance of bending quality, productivity and investment, especially for LSAW pipe …
What Is A LSAW Pipe? - steeljrv
What is a LSAW pipe?. LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.[PDF]
