Pipemaking

McLellan, with extensive experience within the pipemaking sector, can provide specialist expertise for both greenfield projects as well as modifications or upgrades to existing plant and equipment.

Our specialists can provide advice on both seamless and welded pipe technologies.

Seamless pipe is widely used in the construction, oil and gas, chemicals and petrochemical industries and typically falls into the following categories:

  • Oil Country Tubular Goods (OCTG) pipe
    • Tubing and Casing
    • Drill pipe
  • Line pipe
  • Mechanical pipe

Although historically, seamless pipes have been preferred over welded pipes for critical applications, advances in welding technology mean that welded pipes are now of similar quality to seamless pipes in terms of reliability and strength. Categories of welded pipe include:

  • Spiral or Helical Submerged Arc Welded (HSAW) pipe
  • Longitudinal Submerged Arc Welded (LSAW) pipe
  • High Frequency Induction Welded (HFIW) pipe
  • Electric Resistance Welded (ERW) pipe

McLellan can provide specialist expertise on both UOE and JCO forming processes for LSAW large diameter pipe manufacture.

In addition to the main process equipment, our industry experts can advise on pipe and tube finishing lines including:

  • Pipe threading and coupling lines
  • Heat treatment facilities
  • Electro-Magnetic Inspection (EMI)
  • Magnetic Particle Inspection (MPI)
  • X – ray inspection
  • Coupling make-up
  • Hydrostatic testing
  • Drift testing
  • Ultrasonic testing
  • Pipe bending
  • Surface coating
  • Mechanical Expansion
  • Hydrostatic Testing
  • Fluoroscopy Inspection
  • Physical Measurement and Visual Inspection
  • Laboratory Inspection
