PIPEngineering & fabrication
Process piping, carbon to stainless.
Carbon steel and stainless steel piping for process and utility service. Spools are fabricated in the workshop, then installed and tied in on site, including during shutdowns.

under pressure.
- 01 Isometric
Drawn before it's cut.
Workshop isometrics fix every dimension, fitting, weld number and material before the spool is fabricated.
- 02 Spool
Built in the workshop.
Pipe, fittings and flanges are cut, fitted and welded by coded welders, with PMI and Mill Test Certificates traced to every run.
- 03 Install
Into the rack.
The spool is lifted into the pipe rack, set on its supports and brought to the mating flange, including during shutdown tie-ins.
- 04 Bolt-up
Tightened in sequence.
A new gasket is fitted and bolts are tightened in a cross pattern over several passes, so the flange faces close evenly.
- 05 Test
Proven before service.
The system is hydrostatically or pneumatically tested and held, and the test is signed off by the Approved Inspection Authority.
- 06 Hand over
Ready for service.
Test packs, NDT reports and material records go into the QCP data book for handover.
