Dec 19, 2018 · LSAW means Longitudinal Submerged Arc Welding carbon steel pipe. It is a kind of SAW pipe made of steel plates that were hot rolled by JCOE or UOE manufacturing process. JCOE technology means shaping and forming processes. This forming process JCOE includes. JINDAL SAW LIMITED - Steel SWThe Size range of HSAW/ Spiral Pipes:Outer Wall Diameter :Between 18 Inch 100 Inch Wall Thickness :Up to 1 Inch Combined Installed Capacity:0.74 Million Tons P.A (Total 4 Mills) The size range of the LSAW/ DSAW Pipes:Outer Wall Diameter :Between 16 inch 60 Inch Wall thickness : LSAW Pipe Manufacturing Process JCOE Winsteel GroupNov 22, 2018 · Take ultrasonic testing for steel plates before they put into the production line. This kind of steel plate used for welding large-diameter LSAW pipes. 2. Edge preparation milling. Use a milling machine to shape both sides of the steel plate. So as achieve the required plate dimension, the parallelism of the plate edge. 3. Pre-bending
In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.
