LSAW Steel Pipe in stock Product Description 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. Product Specification Product NameLSAW Steel Pipe UsageUsed for low pressure liquid delivery, such as water, gas, and oil.

At least two PQRs should be completed in this project, one of which is manual welding (SMAW) to verify the welding quality and weld repair of manual welding; the other is submerged arc welding (SAW) to verify the welding quality of submerged arc welding. After all test items are qualified, confirm the correctness and feasibility of WPS according to the welding procedure qualification report (PQR). Packaging and Shipping Customers and Exhibition FAQ 1) Fully approved by the major inspection authorities, such as CCS, CE, BV, ASTM, API 5L certification and laboratory accreditation cert, Quality management system cert, Environmental management system cert, Occupational health and safety management system cert. etc. 2) Reasonable pricing 3) Prompt delivery of order 4) Flexible payment modes 5) Rich manufacturing experiences. 6) Comprehensive product ranges 7) No min. order quantity 8) Quick respond after-sale serviceLSAW Steel Pipe in stock website:
