The API 5L specification covers seamless and welded pipes to convey oil, gas, water in the natural oil & gas and petrochemical industries

Reliable Pipes & Tubes Ltd. is stockiest, suppliers & exporters of API 5L Line Pipe, API 5L PSL1 Seamless Pipe, API 5L PSL2 Seamless Pipe, API 5L PSL1 Welded Pipe, API 5L PSL2 Welded Pipe, API ERW Pipe, API HFW Pipe, API SAW Pipe, API LSAW Pipe, API HSAW Pipe, API DSAW Pipe, API 5L Sour Service Pipe, API 5L Offshore Service Pipe.

Reliable Pipes & Tubes Ltd. can supply superior Quality High strength, High Toughness, Homogeneous material and Corrosion Resistant Line Pipes for various special services such as offshore and sour services.

Grades covered by this specification are A25, A, B (and the following “X” Grades), X42, X46, X52, X56, X60, X65, X70, X80.  The two-digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.

API 5L pipes may be classified according to the following criteria:

  • execution: seamless or welded (seamless pipes may be used up to 24 inches, LSAW above 24 inches, ERW up to 20 inches)
  • specification level (API PSL1, PSL2): PSL1 is a standard quality used for pipelines, whereas PSL2 sets more stringent chemical, mechanical properties, and testing requirements
  • surface finish: black, varnish painted, anti-rust oil, galvanized, coated externally (3PL) and/or lined internally
  • ends types: plain, beveled, threaded ends

The main advantages of API 5L pipe are:

  • Resistance to cracking forces that may propagate in long pipelines
  • Sour service suitability
  • Rather inexpensive and long service life (at least grades B, X42)

Size Range

API 5L pipes are available in dimensions between from 2 to 28″  (seamless execution) and up to 80″ in welded execution (generally, LSAW i.e. longitudinal submerged arc welding).

The API 5L and ASME B36.10 pipe dimensions and weights are, in fact, identical.
