EN 10219 S235JRH Submerged Arc Welded Pipe For Dredge Field
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 during producing as well as the inner and outer welding and cold expansion carried out after welding.
When compared UOE vs JCOE pipes, LSAW steel pipe manufacturers in China can produce more sizes as:
Submerged pipelines are made by welding a number of pipes together into a long string. They are floated into place, full of air and then sunk in the desired location (thus ‘sinkers’) by flooding the pipe. At each end of the pipeline, flanged connections or ball-joints are provided to enable the submerged lines to be connected to the floating or landlines.
Land or shore lines are relatively short lengths of standard pipe, bolted together laying onshore. Various devices are incorporated in the land pipeline so it can be moved or extended or to switch the flow to different sections of the discharge area. The line may also be equipped with manual or hydraulically operated valves, Y-pieces and bends of different angles.All pipelines need to be turned regularly during use, to ensure that wear is even and hence pipeline life is maximised.
