API 5L Gr.B Line Pipe

API 5L Gr.B (PSL1/PSL2) line pipe for oil, gas and water transmission projects.

Line pipe to API 5L for transmission projects

API 5L Gr.B covers carbon steel line pipe for oil, gas and water transmission. We supply PSL1 and PSL2 in seamless and welded (ERW/SAW) execution, NPS 2"–24", with hydrostatic test and NDT per the standard.

What to confirm before ordering

Tell us the execution class (PSL1 or PSL2), seamless or welded, and whether you need 3.1 or 3.2 certificates. PSL2 adds CVN impact testing, so pipe availability and price differ from PSL1 — confirming this early avoids re-quotation.

Project support

For EPC buyers we can quote against a full pipe list: mixed sizes, fittings and flanges packed in the same container, one Bill of Lading.
