ISO 3183
ISO 3183 Pipeline
ISO 3183, a renowned standard set by the International Standardization Organization, is pivotal for the Petroleum and natural gas industries. It meticulously outlines the requirements for manufacturing two distinct product specification levels, namely PSL 1 and PSL 2, of seamless and welded steel pipes. These pipes are quintessential for pipeline transportation systems in the petroleum and natural gas sectors. Originating from the harmonization of API Spec 5L, 44th edition (2007), and its second edition, ISO 3183 has undergone rigorous refinements, incorporating clarifications and technical requirements, making it a trusted choice for industry professionals. At UNIACERO, we pride ourselves on adhering to these stringent standards, ensuring you receive products of unmatched quality and reliability.
