COMMERCIAL & INDUSTRIAL GASFITTING, APPLIANCE PIPING & PLUMBING.
Complete Natural Gas and LPG installations across all operating pressures (<200 kPa and >200 kPa), Type A and Type B appliance piping, gas leak detection and leak repairs, water removal from gas installations, commercial fire water services, backflow prevention testing, and full-scope water supply, sanitary, and drainage plumbing.
Class G, Class I(B) & Plumbing
Perth & Statewide WA Mobilisation
Turnkey Compliance Across Western Australia.
At Industry Gas Services, we handle the full spectrum of commercial and industrial gasfitting, from standard low-pressure (<200 kPa) commercial installations and Type A/Type B appliance piping right through to heavy-duty industrial reticulation operating above 200 kPa. Holding both an Unrestricted Class G Gasfitting Permit and a specialist Class I(B) Gasfitting Permit issued by Building and Energy WA, we are authorised for all commercial and industrial Natural Gas and LPG installations under AS/NZS 5601.1 and AS/NZS 1596.
We are also highly experienced in water removal from gas piping and full pipeline repair, including resolving water ingress caused by burst water pipes jetting into adjacent gas lines, cross-connections, or appliance failures. Alongside our gasfitting operations, we are equally skilled in water supply, sanitary, drainage, and commercial fire water services, including the installation, maintenance, and mandatory annual testing of testable backflow prevention devices (DCVs and RPZDs) in accordance with AS/NZS 3500, AS 2419.1, AS 2441, and the National Construction Code (NCC).

- WA Plumbing Contractor & Electrical LicencesAS/NZS 3500 & NCC
Authorised across commercial and industrial water supply, sanitary, drainage, fire water services, and testable backflow prevention (AS/NZS 3500, AS 2419.1, AS 2441, and the National Construction Code), alongside licensed electrical capabilities for burner controls and plant integration.
Core Capabilities & Scope of Work.
Commercial & Industrial Gasfitting & Type A / Type B Appliance Piping (<200 kPa)
Authorised for all commercial and industrial Natural Gas and LPG pipework, Type A and Type B gas appliance piping, hot water systems, commercial kitchens, pool heaters, and industrial laundries under AS/NZS 5601.1 and AS/NZS 1596.
High-Pressure Consumer Piping (>200 kPa, Class I(B))
Design sizing, fabrication, welding/jointing, and installation of carbon steel, stainless steel, copper, polyethylene (PE), and composite gas reticulation networks operating above 200 kPa.
Water Removal from Gas Piping, Ingress Repair & Gas Leak Detection
Experienced in removing water from gas piping and repairing damaged services, including water ingress caused by burst water pipes jetting into underground gas lines. Because we hold both gasfitting and plumbing licences, we repair both the burst water pipe and the gas line, then dewater, dry, purge, pressure test, and recommission the gas installation.
Water Supply, Sanitary & Drainage Plumbing (AS/NZS 3500 & NCC)
Equally skilled across commercial and industrial water supply, sanitary, and drainage plumbing. We deliver cold and heated water reticulation, backflow prevention, trade waste, sanitary plumbing, below-ground drainage, and plant connections compliant with AS/NZS 3500 and the National Construction Code (NCC).
Commercial Fire Water Services & Backflow Prevention Maintenance
We specialise in commercial fire water services and the installation, maintenance, and mandatory annual testing of testable backflow prevention devices, including Double Check Valves (DCVs) and high-hazard Reduced Pressure Zone Devices (RPZDs). We also provide expert mechanical repairs, fire hose reel change-outs, and landing valve replacements to ensure full compliance with AS/NZS 3500.1, AS 2419.1, and AS 2441.
Below-Ground PE Piping, Electrofusion & Butt Welding
Complete trenching and installation of underground polyethylene (PE) gas and water pipelines, certified electrofusion and butt welding, backed by strict excavation procedures and underground asset locating prior to excavation.
Protective Wrapping & Anti-Corrosion Coatings
Competent application of specialist pipeline protective wraps, heat-shrink sleeves, and corrosion-prevention coatings across buried lines, risers, welds, and flanges using Stopaq, Canusa, Denso, and Solartech systems.
Pressure Control, Metering & Over-Pressure Protection
Installation and calibration of primary and secondary pressure regulating stations, sub-metering skids, slam-shut valves, relief valves, and active/monitor regulator assemblies across all pressure regimes.
Engineered Ventilation, Flueing & Inert Purging
Design verification and installation of plantroom ventilation, exhaust flues, dilution air systems, and controlled nitrogen/inert gas purging of new and modified pipelines prior to live commissioning.
