Product introduction
Application scenario
PSL1 HFW: land low-pressure oil and gas transportation (≤6MPa), normal-temperature non-corrosive medium (crude oil/water), municipal pipe network and structural pipes.
PSL2 HFW: high-pressure/medium-high-pressure trunk lines, corrosive environment containing HS/CO, low-temperature working conditions (≤-10℃), deep-sea/submarine pipelines and long-distance pipelines with strict regulatory requirements.
Key points of selection and procurement
Clear grade: API 5L PSL1 or PSL2 must be marked in the contract and cannot be omitted.
Steel grade matching: steel grade is selected according to design pressure/temperature/corrosion, and high steel grade (X65+) is preferred to PSL2.
Inspection requirements: PSL2 needs 100% NDT+water pressure, impact report, material list and heat number traceability.
Process qualification: HFW shall indicate high frequency induction (HFI) or resistance welding (ERW), and provide weld process qualification.
