API 5L PIPES SUPPLIERS AND EXPORTERS
API 5L defines the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the utilization of a pipeline in the transit of petroleum and natural gas. For material use in a sour maintenance application, refer to Annex H; for offshore services application, refer to Annex J of API 5L 45th Edition.
Knowledge of the planned end use and desired method of pipe fabrication is a compulsory prerequisite for nominating the relevant material specification, pipe grade, individual requirement (ASTM), API 5L product specification level (PSL), API 5L Annex Requirement, or CSA Z245.1 category or service group. An API 5L Pipes is manufactured by adhering to the specifications laid down by the International Organization for Standardization (ISO) 3183. It assigns the standards for the materials, gear, and seaward constructions for petrochemical, petrol, and flammable gas enterprises.
