Grades: GR.A, GR.B, X42, X46, X52, X56, X60, X65, X70
Sizes:
Outer Diameter Range:1/2" to 2", 3", 4", 6", 8", 10", 12"
Thickness Schedule: SCH 10,SCH20, SCH40, SCH STD, SCH80
Product Specification Level (PSL):
- PSL1: Basic requirements for standard applications.
- Key Differences from PSL2:
- Less stringent chemical composition controls.
- No mandatory Charpy V-notch impact testing (optional unless specified).
- Lower maximum carbon equivalent (CE) limits for weldability.
- Permissible for general, non-sour service environments.
Manufacturing Processes:
- Seamless: Hot-rolled or cold-drawn.
- Welde: Electric Resistance Welded (ERW) or Submerged Arc Welded (SAW).
Applications:
- Onshore oil/gas transmission pipelines.
- Water injection lines.
- Low-pressure gathering systems.
- Structural applications (e.g., piling).
