ASTM A106 Gr.B Seamless Carbon Steel Pipe Sch40/Sch80 Heavy Wall for Boiler
1.Product Description
API 5L carbon steel pipe is manufactured to API Specification 5L, Line Pipe, for onshore and offshore transmission of oil, gas, and water. Steel grades include Grade B, X42, X52, X60, X65, X70, and X80, where the figure after X indicates minimum yield strength in ksi. Processes cover seamless (SMLS), LSAW, SSAW, ERW, and EFW. Quality levels are PSL1 and PSL2, with PSL2 imposing stricter toughness, chemical, and NDT requirements for high-pressure, sour, and low-temperature services. OD ranges from 10.3mm to 2032mm; wall thickness and length are customized per project.
2. Product Applications
Onshore and subsea long-distance oil/gas pipelines
Oilfield gathering, water injection, and polymer injection networks
Process piping in refineries and chemical plants
City gas, water supply, and district heating mains
Load-bearing members for offshore platforms, bridges, and steel structures
3. Product Advantages
Grades from B to X80 for tiered selection by design pressure; X65/X70 dominate high-pressure trunks; X80 enables wall thinning for high throughput
PSL2 grades offer excellent low-temperature toughness and dynamic crack arrest verified by DWTT shear area
Sour service series compliant with NACE MR0175 for H₂S media, hardness ≤250 HV10
Low CEV design (X65≤0.42%) ensures easy field welding with reduced preheat and rework
Fully traceable from heat number, rolling batch to inspection records
Tight OD, ovality, and wall tolerance for efficient mechanized fit-up and automatic welding
Compatible with FBE, 3LPE, 3LPP coatings; 50+ years service life in buried conditions
