Engineering Standards & Fabrication Capabilities
Plastic Welding for Industrial Tanks, Vessels, and Assemblies
When plastic components need to be permanently joined into leak-proof structures, plastic welding is the fabrication method of choice. Unlike mechanical fastening or adhesive bonding, welded thermoplastic joints become a continuous part of the base material - critical for tanks, vessels, and process equipment that must hold pressure or contain aggressive chemicals.
Perspex Online fabricates and repairs welded plastic structures for industries where material failure carries serious consequences, including chemical processing, water treatment, mining, and electroplating.
Applications Across Demanding Industries
Plastic welding suits any application where chemical resistance, structural integrity, and long service life are priorities. Common project types include chemical dosing tanks, electroplating baths, process trays, containment bunds, agricultural spray equipment, and water treatment infrastructure.
Industries we regularly supply include:
- Chemical processing - storage and transfer vessels in polypropylene and PVDF
- Water treatment - HDPE tanks, sumps, and filtration housings
- Mining - wear-resistant liners and custom fabricated enclosures
- Electroplating - acid-resistant polypropylene and PVC tanks
- Agriculture - chemical-resistant spray and storage equipment
Repair and Modification of Existing Plastic Equipment
Not every job requires a new build. Cracks, joint failures, or damaged fittings in an existing tank or vessel can often be repaired by welding rather than replaced outright. Perspex Online assesses and repairs plastic equipment in materials including HDPE, polypropylene, and PVC, extending service life and reducing downtime costs.
Modification work - adding flanges, relocating outlets, increasing capacity - is handled in the same workshop using the same certified welding processes as new fabrication.
Workshop-Backed Fabrication, Not Trade Assistance
Perspex Online operates as part of P&M Plastics' professional fabrication facility, which means plastic welding jobs are completed with industrial-grade equipment, certified welders, and full quality oversight - not handed off to a subcontractor. This is a working fabrication workshop, capable of handling single-off repairs through to ongoing production of complex welded assemblies.
All structural welding is performed to Australian standards, with pressure testing available for tanks and vessels where specified.

Applications for Plastic Welding
Chemical Tanks
PVC fabricated tanks for aggressive chemical storage and dosing.
Plastic Tanks
HDPE fabricated tanks for water, chemical, and industrial storage.
Marine Tanks
HDPE tanks for bait, live wells, and onboard water storage.
Containment Systems
PVC bund lining and secondary containment for chemical storage.
Welded Assemblies
Hot-air and extrusion-welded PP fabrications for tanks and ducting.
Waste & Grey Water Tanks
Plastic materials are commonly used for wastewater storage tanks because they offer corrosion resistance, chemical compatibility, and long-term durability in wet environments. Unlike metal tanks,…
Vehicle-Mounted Plastic Tanks
Vehicle-mounted plastic tanks are used for storing water, waste, fuel, chemicals, and process fluids in utes, 4×4 vehicles, trucks, trailers, and service vehicles.
Truck Liners
HDPE and UHMWPE lining for truck trays, hoppers, and chutes.
