Pipemaking

Seamless pipe is generally used in applications which involve high operating pressures and is widely used in the construction, oil and gas, chemicals and petrochemical industries. Seamless pipe categories include:

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

With advancements in welding technology, welded pipes are generally now considered 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

Our expertise includes both UOE and JCO forming processes for LSAW large diameter pipe manufacture.

In addition to the main pipemaking equipment, we can advise on pipe and tube finishing lines including:

• Pipe threading and coupling lines
• Heat treatment facilities
• Coupling make-up
• Pipe bending
• Surface coating
• Mechanical Expansion

The choice of seamless or welded pipe for a particular application, now, largely depend on the pipe dimensions and tolerances required. Stringent quality requirements must be met for both seamless and welded pipe in order to satisfy applicable certification criteria in addition to often wide-ranging customer requirements dictated by particular applications. In order to achieve this, a wide array of Non-Destructive Testing (NDT) methods is used including:

• Electro-Magnetic Inspection (EMI)
• Magnetic Particle Inspection (MPI)
• X – ray inspection
• Hydrostatic testing
• Drift testing
• Ultrasonic testing
• Fluoroscopy inspection
• Physical measurement and visual inspection
• Laboratory inspection

Using our extensive expertise in the industry, we can advice on the most suitable process route in addition to the required finishing and testing facilities to meet your customer requirements. For existing pipemaking facilities, we can provide tailored advice to help you optimise operations, reduce waste and improve operating costs.
