API 5L PSL1 Vs PSL2 Pipes
An API 5L pipe is manufactured by adhering to the specifications laid down by the International Organization for Standardization (ISO) 3183. It standardizes the criteria for the materials, equipment, and offshore structures for the petrochemical, petroleum, and natural gas industries. PSL 1 and PSL 2 are the two Product Specification Levels that have been recognized by the technical committee which are mostly used in Oil and Gas Industries.
Trio Steel API 5L Pipes suppliers further adhere to the International Organization for Standardization ISO 3183 and it specifies the production of two product specification levels (PSLs): API 5L PSL1 Vs PSL2 Pipes. The previous is a standard quality for line pipe though the last conveys extra mechanical, synthetic properties, and testing requirements. These pipes are recognized and trusted names for organizations working in the oil, flammable gas, and petrol area just as different areas where API 5L Pipes are needed to do tasks.
