Technical specifications
Fittings are where a pipeline changes direction, and that is where it usually fails first. We supply seamless and welded fittings to ASME B16.9 with bevelled ends to B16.25, in schedules from SCH10 to XXS, each one traceable to its heat number and supplied with the mill test certificate.
Main applications
- Refinery and petrochemical piping
- Power plant piping
- Gas transmission lines
- Water treatment plant
- Shipbuilding and offshore piping
Packing and delivery
Wooden cases with painted or oiled ends, fittings segregated by size and heat number, and a dimensional inspection report with the shipment.

FAQ
Long radius or short radius elbows?
Long radius (1.5D) is the standard where pressure drop and pigging matter; short radius (1D) is used in tight spaces. Both are supplied — state it on the enquiry because the price differs.
Can you supply fittings with a specific wall thickness match?
Yes. Send the pipe schedule and we will match the fitting bore so that the internal misalignment at the weld stays within your tolerance.
