What we make

Six lines.
One standard.

Every product we make, from a single stud bolt to a finished spool, carries its heat number, its test record and our name.

Flagship
Finished flanged spools with elbows and tees.
06

Pipe spools

Pipe, fittings and flanges cut, fitted, welded and tested in our shop to your isometrics, then delivered ready to bolt up on site.

ASME B31.3Carbon, stainless, duplexHydro testedPickled and passivated
Stacked pipe ends, seamless and welded.
01

Pipes

Seamless and welded pipe for process, utility and cooling-water lines.

ASTM A312A106 Gr. BSch 5S to XXS
Bundles of bright annealed tube or U-tubes.
02

Tubes

Instrumentation, heat exchanger and U-tubes held to tight OD and wall tolerances.

ASTM A213A269U-bends
Elbows, tees and reducers laid out on a bench.

Fittings

Butt-weld and forged fittings: elbows, tees, reducers, caps and stub ends.

ASME B16.9B16.11MSS SP-43
Stud bolts and heavy hex nuts in a crate.
04

Fasteners

Stud bolts, hex bolts, nuts and washers matched to flange class and service.

ASTM A193 B7A194 2HB8 / B8M
Machined weld-neck and blind flanges.

Pipe spools

Five products.
One spool.

Pipe, fittings, flanges and fasteners are joined in our shop to your isometrics. Your site crew bolts up instead of welding.

  1. 01Verify

Data centres

From chiller
to chip.

AI racks run too hot for air. Liquid cooling needs clean, leak-tight stainless steel from the plant room to the rack, and we prefabricate it.

  • 01 Facility water headers and pump-skid spools
  • 02 CDU piping in 304 and 316L stainless
  • 03 Row manifolds and rack-drop assemblies
