Why DUSASPUN
Reliable supply, built in
Program Certainty
Nine weeks from order confirmation to Australian port. That is a date, not a range. Send Empire your pipe schedule and the team will confirm against your program without the back-and-forth.
Engineered to Any Diameter
DUSASPUN can design and produce any internal or external diameter. Load class can be adjusted up to Class 10 to suit your project. The final design follows the approved drawing as submitted.
Certified Quality
Manufactured to AS/NZS 4058 under ISO 9001 certification (LRQA). Every rubber ring joint is tested for watertightness above 90kPa before it leaves the factory.
The Product
RRJ type
reinforced concrete pipe
DUSASPUN reinforced concrete pipe (RCP) is supplied by Empire Infrastructure for open trench and jacking installations across Australia and New Zealand. Each pipe uses a socketed L-Skid joint with rubber gasket, compliant with AS 1646 and tested for watertightness above 90kPa before despatch.
Steel reinforcement is manufactured to ASTM A.496-90a and AS 1303, cement to ASTM C150 Type I, and aggregates to ASTM C33/C33M. The standard range runs DN300 to DN1650 at a Class 2 proof load rating, with higher load classes available up to Class 10 and any non-standard diameter engineered on request.
DUSASPUN RCP is also available as reinforced concrete jacking pipe on the same nine week lead time window, for trenchless and microtunnelling drives across any diameter in the standard range.
