API 5L SPECIFICATION

API 5L pipes may be classified according to the following criteria:
1, Execution: seamless or welded (seamless pipes may be used up to 24 inches, LSAW above 24 inches, ERW up to 20 inches)
2, Specification level (API PSL1, PSL2): PSL1 is a standard quality used for pipelines, whereas PSL2 sets more stringent chemical, mechanical properties, and testing requirements
3, Surface finish: black, varnish painted, anti-rust oil, galvanized, coated externally (3PL) and/or lined internally
4, Ends types: plain, beveled, threaded ends

The main advantages of API 5L pipe are:
1, Resistance to cracking forces that may propagate in long pipelines
2, Sour service suitability
3, 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).
