X46 PSL1 Seamless Line Pipe

ISO 3183 L320 PSL1 — petroleum and natural gas pipeline transportation pipe


API 5L X46 PSL1 seamless line pipe ISO 3183 L320

Savoy Piping Inc. supplies API 5L X46 PSL1 seamless line pipe for oil and gas pipeline transportation systems — commonly mapped to ISO 3183 L320.

Order by grade + PSL + product form, OD/wall, ends, delivery condition (R/N/Q/M for PSL2) and the full test / annex package.

Typical strength guide: yield min ~46 ksi (317 MPa), tensile min ~63 ksi (434 MPa). PSL1 is the baseline product specification level — upgrade to PSL2 when toughness and extended testing are mandatory.

What is API 5L X46 PSL1?

API 5L covers seamless and welded steel line pipe for pipeline transportation systems. X46 is defined by minimum yield strength (~46 ksi). PSL1 sets the product specification level — chemistry, toughness and testing depth differ between PSL1 and PSL2.

Typical applications

  • Oil and gas transmission / trunk pipelines
  • Onshore and offshore pipeline packages specifying API 5L X46
  • Standard PSL1 line-pipe packages
  • Dual-certified API 5L / ISO 3183 L320 supply (project-dependent)
  • Optional sour-service / HIC / SSC routes when the PO requires them

How to order X46 PSL1

State API 5L edition, grade X46, PSL1, seamless, OD/wall, ends, coating, delivery condition and MTC level (EN 10204 3.1 / 3.2). For sour service, call out NACE / HIC / SSC annexes explicitly.

Frequently asked questions — API 5L X46 PSL1

What is API 5L X46 PSL1 seamless pipe used for?

API 5L X46 PSL1 seamless line pipe is used for petroleum and natural gas pipeline transportation systems — oil, gas and related transmission lines ordered to API 5L (often dual-mapped to ISO 3183 L320).

What does the X46 grade number mean?

The digits after X are the minimum yield strength in ksi × 1000. X46 means about 46 ksi (317 MPa) minimum yield. Typical tensile minimum is about 63 ksi (434 MPa) — confirm against the ordered edition and PSL tables.

PSL1 vs PSL2 for X46 — which should I order?

PSL1 is the standard product specification level. Choose PSL2 when the project requires tougher chemistry, notch toughness and extended NDE/documentation.

Seamless or welded for API 5L X46?

Seamless is preferred for many smaller OD / high-integrity packages. Large diameters often move to LSAW/DSAW/HSAW welded pipe — follow the approved construction on the PO.
