Duraduct, formed in 1970 and acquired by the STM Group in 2001, has a range of tubes and pipes that complements STM's stainless tube mill portfolio by extending the range of diameters offered. It has manufacturing operations in Melbourne, Sydney, Brisbane and Perth and sales offices in all Australian states.
The Duraduct method of tube and pipe production is spiral weld and roll form (lockseam) in both stainless and mild steel.
The spiral weld tube and pipe is produced for high-pressure and structural applications in a diameter range up to 1,626mm. The lockseam tube is produced for low-pressure ducting and structural applications in a diameter range up to 2,438m.
Duraduct manufactures a complementary range of bends, tees and reducers in welded and lockseam to match both tubular systems and customer specials such as spool pieces. Stiffening rings are also fabricated in our engineering workshops.
As a complement to its spiral piping systems Duraduct offers a series of industry-specific products and services as follows.
The patented Dura-Seal mechanically fixed and leak-proof rubber self-sealing jointing system is used for the easy installation of ductwork.
Duraduct's lockseam insulated ducting system has an outer steel casing, internal fire-resistant fibreglass insulation and an acoustic perforated or plain metal-core liner.
The PolySteel™ is a composite pipe consisting of an outer spiral steel casing and an inner poly (HDPE) lining. This piping product has been designed for the transportation of abrasive and corrosive fluids under pressure.
Our lockseam tube is used for the ventilation (supply or exhaust) of mines, tunnels and shafts, both on a temporary basis during construction and as a permanent installation.
Duraduct lockseam tube is used for ventilation ducts, electrical conduit and cable channels in concrete floor and slab constructions.
Duraduct provides a lockseam tube for use in concrete column forms and other building construction applications.
Duraduct lockseam corrugated pipe is for use in the construction of culvert, storm water, sub-soil drainage and other irrigation applications.
We offer stainless and mild-steel fabricated fittings for gas and fluid transmission tube and pipes, as well as structural applications. These products are used in the mining/industrial waste, power generation, water and waste treatment, and building and construction industries.
Our carbon-steel spiral-formed ducting tube and fittings can be used for transmission (low pressure), structural, gas ducting, and structural hollow and chute applications. These products are used in the building and construction, mining, agriculture, industrial, and utilities markets.
Internal poly (HDPE)-lined spiral mild-steel pipe is used as a pressure pipe for the transmission of corrosive and abrasive fluids. These products are used in the mining, mineral processing, industrial and utilities markets.
Typical applications include for mining and power-generation slurry pipelines, minerals and waste in fluid-suspension pipelines, and chemical and corrosive product-transmission pipelines.
Duraduct can also provide on-site installation of tubular systems for its customers. This market offer brings the manufacturer and installer together as one and provides a more direct service to the customer and better assurance to the end-user that specifications and individual requirements are being met in service.
