Overview
LSAW steel pipe supports large-diameter line and structural export packages where longitudinally welded pipe is specified instead of ERW or seamless routes. Confirm governing standard and grade, outside diameter, wall thickness, end preparation, length, and the NDT plus hydrostatic scope required by the project before release. Heat identity, weld inspection records, and MTC documentation should match pipe marks for destination acceptance. Send the size list, quantity, coating if any, destination port, and third-party inspection preference so Tsingshan Steel can propose a practical supply path.
