A heavy-duty line pipe manufactured to API 5L X70 specification, produced as Longitudinal Submerged Arc Welded (LSAW) pipe and intended for high-pressure transmission of oil, gas and water. Engineered for pipeline systems that require a high yield and tensile strength, this X70 grade pipe is suitable for both onshore and offshore pipeline projects and other demanding transmission applications.

Key features:

  • Standards & grade: API 5L X70 (PSL2 available from select suppliers)
  • Manufacturing type: LSAW (longitudinal seam welded) suitable for pipeline service
  • Mechanical properties: minimum yield strength ~480 MPa; tensile strength typically 600–750 MPa; permissible yield-to-tensile ratio ≤ 0.85
  • Typical chemical composition: C 0.04–0.16% (max), Si ≤ 0.55% (max), Mn ~1.10–1.70% (range), P ≤ 0.035% (max), S ≤ 0.035% (max)

Surface finish, coatings and packing:

  • Available surface treatments include black paint, varnish, anti-rust oil or custom coatings to project requirements
  • Ends can be supplied with protective plastic caps
  • Packing options: steel packing bands, wooden or steel crating, or customized packaging per buyer specification

Applications:

  • Transmission pipelines for oil, natural gas and water
  • Onshore and offshore pipeline systems and related pipeline infrastructure

Commercial notes:

  • Typical India price range (indicative): US$ 417–520 per metric tonne (subject to confirmation at time of enquiry, depending on dimensions, coating, PSL level and order quantity)
  • Customization: wall thickness, diameter, end preparations and coating specifications can be supplied to client requirements; inspection and testing per API 5L available on request

This product is offered for B2B procurement of pipeline-grade steel line pipe where high strength, reliability and compliance with API 5L requirements are essential.
