Precision Piping Solutions
piping fabrication
Specialist piping fabrication delivered with precision, quality, and technical expertise.
We offer a full range of specialist piping fabrication services to meet our clients’ needs. Walz Group’s highly qualified metalworkers have technical knowledge of complex fabrication and welding applications.
Our piping fabrication teams are fully qualified to provide specialist welding services for multiple materials, including carbon steel, stainless steel, HDPE, CPUB, PUDF, PVC and FRP. We work across a range of industries, with a wealth of experience in fabricating complex piping. Our dedicated facility in Gladstone features massive laydown and fabrication areas and the latest specialty equipment
We are committed to delivering quality outcomes that deliver value. Our pressure welding services are fully compliant with the quality requirements of ISO 3834 and meet our clients’ specifications for both welded and PWHT equipment. The team is also highly accomplished in chromium carbide iron alloy weld overlay procedures for pressure equipment in accordance with ASNZS 3992 and ASME IX.
All our workshop quality systems are independently certified to ISO9001 and meet the needs of our client’s quality requirements.
The Scope incorporates the fabrication and installation of new carbon steel pipelines (Bauxite Slurry line, Caustic line, CGW line) from the wharf to South Trees Island and from STI to the mainland via the causeway.
After working together successfully on previous projects, Wesfarmers Curragh Pty Ltd (WCPL) engaged Walz Group to support the installation of a new tailings retreat circuit to the Coal Preparation Plant 1 (CPP1) at its Blackwater mine in Queensland. We’ve worked at Curragh before and have gained a solid understanding of the mine’s operational requirements.
Formerly owned by Wesfarmers Resources, the Curragh Coal Mine (now operated by Coronado Curragh Pty Ltd) is located in Queensland’s Bowen Basin, 30km north of Blackwater. The main product from the mine is metallurgical (coking) coal for export.
The Dalby Ethanol Plant is Australia’s first grain-to-ethanol facility. Each year the plant converts nearly 200,000 tonnes of sorghum into 76 million litres of ethanol. The product remaining after ethanol distillation — known as sillage — is separated and concentrated using centrifuge and evaporation technology to form a high energy, high protein animal feed known as wet distiller’s grain. The soluble dry matter, known as syrup, is blended with the Wet Distiller’s Grain (WDG) and sold to the local animal feed market as Wet Distiller’s Grain with Solubles (WDGS).
Peak Downs Mine (PDM) identified the Coal Thickener Bridge was at its end of life and required replacing. It supports a range of services including mechanical drives, hydraulics, electrical and control services, flocculent dosing system, compressed air and coal slurry and water pipes. It also provides the suspension of the feed well and thickener raking system.
Our client, Sedgman, has operated the Sonoma plant since it was constructed in 2007, and were seeking support for the detailed design, engineering, procurement, and construction of the High Cut Low Cut Brownfield Upgrade of the coal handling and preparation plant.
Quality and Compliance
Quality is at the core of our fabrication services. Our processes are governed by robust quality assurance systems, documented traceability and inspection regimes to ensure structural integrity and compliance with client and industry standards. Every spool and assembly is verified for dimensional accuracy, welding integrity and specification alignment before release.
Collaborative Delivery
We work collaboratively with clients, engineers and site personnel from design review through to fabrication and handover. This integrated approach ensures clarity of requirements, consistency in execution and responsiveness to changing project needs — giving clients confidence from workshop to site.
