Typical applications

X52(L360) is normally specified for LSAW and HSAW linepipe for oil and gas transmission, high-pressure trunk lines, sour-service flowlines, and pipe fittings and bends.

We supply it cut to size by plasma, laser or waterjet, with edges machined or flame-cut to your drawing, and can deliver in the heat-treatment condition your fabrication procedure requires.

Linepipe plate components cut to drawing with rounded cut-outs
Plate components cut to drawing with rounded cut-outs, edges cleaned and inspected before packing.

Delivery condition

TMCP or normalized, in PSL1 or PSL2. PSL2 supplementary requirements and HIC / SSC testing to NACE are available for sour service.

Available forms and services

  • Plate 6 – 200 mm thick, width to 4 000 mm, length to 14 000 mm
  • CNC plasma, flame and laser cutting from your DXF / DWG drawing
  • Normalizing, quenching and tempering, and PWHT simulation
  • Edge bevelling, drilling, rolling to diameter on request

Inspection and certification

PSL2 supplementary requirements (SR1–SR18); HIC / SSC testing to NACE for sour service; UT to EN 10160; EN 10204 3.1 / 3.2 mill test certificate

Seaworthy packing — bottom skids, steel strapping, VCI film and edge protection — is standard for sea freight. Container loading plans with piece weights are issued before shipment.

About the equivalent grades. X52(L360) is nearest to ISO 3183 L360 / API 5L X52. These designations sit at a comparable strength and toughness level, but chemistry limits, impact temperatures and permissible thickness ranges differ between standards. Treat the comparison as a starting point for engineering review, not as a declaration of interchangeability.
