GOST OHSAS 18001 EN10217 LSAW Steel Pipe For Boliers
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.
Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter “J”, “C”, “O” or “U” shape, then expansion) forming processes. Furthermore, the mechanical properties of the pipe base metal and weld metal were tested, and the results were in accordance with the corresponding pipe specification API SPEC 5L or DNV-OS-F101, which showed that domestic LSAW pipes could be used for oil and gas pipelines.

| A.Without purchaser's agreement with a table does not contain ingredients can not deliberately to join in the steel, unless in order to complete the casting and is likely to add ingredients, should take reasonable measures to prevent the other added ingredients or other materials used in machining process of the cracks. B, the content of these components don't need to report, unless specially added into the casting C option 3: in order to facilitate subsequent forming operation, the content of the content of copper and tin can be lower than the specified standards. D if steel contain the most plenty of other nitrogen binding elements, can't apply this request, this kind of circumstance should issue a report. |
