Pipeline Construction

PWS have the capability and capacity to undertake large scale HDPE pipeline construction. Including the capacity to design any pipeline to meet your requirement and can provide total pipeline construction solutions.

PWS can supply, deliver and install pipelines including earthworks, HDPE poly welding, property outlets, air valves, scour valves and connection to existing infrastructure inclusive of commissioning and hydrostatic pressure testing.

Works are carried out by our highly qualified and experienced staff using a vast array of our own equipment including;

• McElroy Tracstar HDPE Welders capable of all size HDPE high pressure pipe welding
• Hydrostatic Test Units
• Excavators (up to 50t)
• Tip Trucks
• Telehandlers
• Tilt Trays
• Service Trucks
• Generators
• 4 x 4 mine spec. fit-off trucks
• Prime Mover and Semi Float

As part of our quality assurance processes all pipe welding can be data logged with GPS co-ordinates of welds tracked and logged. This information is stored in a database and access can be provided to the client with prior arrangement.

Information that is captured and logged for the welds will include a joint analysis providing information on the operator, machine used for welding, pipe specifications (thickness, size etc.), piston specifications, bead up pressure, heat soak pressure, fusion specification, open and close times, location, temperature and time of weld.

Solutions for Mining, Civil, Aquaculture and Agriculture

PWS are a local Tasmanian firm dedicated to delivering high quality and fit for purpose solutions to various industries.

PWS have the capability within our dedicated team of qualified and experienced staff to provide HDPE / poly welding solutions, such as butt welding, electrofusion welding and extrusion welding services for the mining, civil, aquaculture and agriculture industries.

In delivering pipeline solutions our team at PWS have the proven ability to effectively manage challenging projects. Depending on the site limitations HDPE pipeline construction can be either welded in sting or insitu, including in trench tie in welds if required.

The versatility of our team enables PWS to construct and manage the installation of various forms of infrastructure onsite, such as pumps, pump stations, manifold stations, tie in connections with existing infrastructure (HDPE or steel) or water storage.

The PWS Project management team will work closely with our onsite teams to ensure completion of the works, with an emphasis on quality and professionalism. Balancing the technical and complex issues, whilst keeping a tight control of project scope and costs, ensuring timely delivery and most importantly client satisfaction.

Hydrostatic Flushing & Testing

PWS takes responsibility for all hydrostatic testing on our projects, ensuring that pipelines meet all technical specifications for our clients. We’ve developed a rigorous Quality Assurance (QA) process to conduct testing, maintaining meticulous standards to meet QA requirements. Investing in specialised equipment, we ensure successful and safe testing of our infrastructure.

We’ve designed flushing and testing procedures tailored to specific client needs, with a focus on environmental protection. Our approach includes capturing flushing water and debris to prevent localised erosion or scour, particularly in testing locations near private property and assets.

Equipped with a trailer-mounted testing facility, flow meters, and pipe connections, PWS efficiently fills, flushes, and tests pipelines while accurately recording flushing volumes and hydrostatic pressure. Upon completion, detailed records are provided to clients for inclusion in As-Constructed records, ensuring transparency and compliance.
