Welding and maintenance for the Surat Basin gas industry
The Western Downs sits on top of one of Australia's biggest coal seam gas regions. WJC supports gas operators and their contractors with certified pressure and pipeline welding, fabrication and mechanical fitting, mobilised from Dalby.
Gas industry services
- Certified pressure welding for steel pipelines to AS/NZS 3992
- In-situ pipeline welding, tie-ins and weld remediation
- Fabrication of spools, skids, supports and access steel
- Pump, valve and compressor-related mechanical work
- Shutdown and maintenance crews for processing facilities
- 24/7 breakdown and emergency repairs
Close to the gas fields
Our Dalby base is central to the Surat Basin gas fields that stretch from Tara and Dalby out past Chinchilla, Miles, Condamine and Wandoan, and west to Roma and the Wallumbilla gas hub. That means shorter travel, faster response and lower mobilisation costs.
Our crews hold the qualifications, inductions and high risk work licences gas sites require, including confined space entry and working at heights.
