LSAW Steel Pipe Manufacturer — Large Diameter API 5L PSL2 Line Pipe

Longitudinal submerged arc welded (LSAW) pipe, OD 219–3000 mm, WT 7.92–50 mm, API 5L Grade B–X60, EN 10219. LSAW pipe for oil & gas from a China ISO 9001 mill.

• Standards & grades: LSAW pipe is manufactured to GB and ASTM standards and EN 10219 (cold-formed welded structural hollow sections). For line-pipe duty it is supplied to API 5L, PSL1 or PSL2 depending on project specification. PSL2 (the higher product specification level) requires tighter chemistry limits, mandatory Charpy V-notch impact testing ((typically at 0°C to −20°C) and non-destructive testing of the full weld. All production runs under the ISO 9001 quality system (No. 31325Q300277R0S).
