Pipe and piping fittings
Line pipe
Transporting fluid or connecting process components within a pressure boundary
Specialist selection guide
What should be reviewed before selecting this product?
Line pipe transports oil, gas, water or other fluids over distance. Product specification level, grade, diameter and wall, toughness, sour service, manufacturing route and traceability are core purchase data.
Technical selection path
- 1
Specify standard edition and PSL
- 2
Define grade, outside diameter, wall and length
- 3
Review design pressure, strain-based design and low temperature
- 4
Declare sour-service or carbon-dioxide transport requirements
- 5
Specify hydrotest, NDE, marking and traceability
Key strengths
- Defined manufacturing and traceability framework
- Wide grade and product-level range
- Coverage of welded and seamless pipe
Selection limitations
- Grade alone is not enough for selection
- PSL 1 and PSL 2 do not have identical requirements
- Handling, storage and coating damage affect final integrity
Typical applications
Where can this option be considered?
- Oil and gas transmission pipelines
- Gathering and export lines
- Water and energy transport under project specifications
Reference standards
A standard does not replace the project specification
Common technical questions
Concise answers before enquiry
How do PSL 1 and PSL 2 differ?
PSL 2 generally adds requirements for chemistry, mechanical properties, testing and traceability; details must be taken from the ordered edition.
Is API 5L alone sufficient for in-plant piping?
Not necessarily. The piping design code, project material class and application limits must independently establish whether the pipe is suitable.

Technical attributes to review
Final values must come from project specifications, calculations and manufacturer data. This table defines the information scope.
Enquiry checklist
Include this information with your request
Nominal and outside diameter
Schedule and wall
Manufacturing route
Material and grade
Corrosion allowance
Documentation and testing
Before substitution
A matching name does not guarantee interchangeability
Installation dimensions, pressure rating, wetted materials, sealing design, construction standard, testing and documentation must be checked independently.
