In-House Services

In-House Fabrication and Maintenance Services

Beyond design, we have full in-house fabrication capabilities and offer a turn-key approach for complex piping and spool fabrication.

Our workshop in Perth is well equipped with high-end equipment , and our coded fabricators are industry-leaders to bring you peace of mind regardless of the pressure in your piping system. Most pipe spooling work is done in accordance with ASME B31.3, ASME B31.1, and AS 4041, although all other standards and specifications can be accommodated. This is backed up with a thorough quality assurance system for full traceability.


PSI also has the ability to complete shear, bevel and cut groove piping from 4 inch to 65 inch with our US manufactured and purpose built Lathe.
