CSA Z245.1 Submerged Arc Welded Pipes for Oil and Gas Pipelines
The CSA Z245.1 standard covers submerged arc welded pipes, mainly used in oil and gas pipeline systems. Its specified outer diameter range is 219mm to 3620mm, and the wall thickness and grade (from grade 172 to grade 550) are clearly classified. This standard classifies steel pipes into three categories based on the toughness requirements for pipe body notches: Class I does not require proof of toughness, Class II requires verification of energy absorption and fracture appearance, and Class III only requires verification of energy absorption.
Product Classification and Technical Requirements
The standard specifies in detail the size, grade, and category of steel pipes, with outer diameter and wall thickness parameters referring to the standard table. Grade classification is based on material strength, while category classification is based on toughness testing requirements. In addition, the welding process must comply with relevant sub standards (such as CSA Z245.11), and corrosion protection must meet the specifications for external epoxy resin or polyethylene coating (such as CSA Z245.20, Z245.21). During the production process, destructive tests such as flattening tests and tensile tests are required to ensure product quality.
Application and testing requirements
This standard steel pipe is widely used in fields such as fluid transportation, heat exchange, mechanical structures, etc. The manufacturer provides material certification and uses quality control methods such as X-ray tube testing and welding process evaluation. The testing equipment includes a steel pipe tensile testing machine, and the coating needs to pass tests such as adhesion and corrosion resistance. During the certification process, it is necessary to evaluate the design, materials, welding, and anti-corrosion measures.
