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. 1

    Specify standard edition and PSL

  2. 2

    Define grade, outside diameter, wall and length

  3. 3

    Review design pressure, strain-based design and low temperature

  4. 4

    Declare sour-service or carbon-dioxide transport requirements

  5. 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.

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.
