- Tight joints and lower treatment costs
- Superior flow characteristics
- Stress crack resistance
IPEX Ultra-Rib is a gravity flow PVC sewer pipe with concentric reinforcing ribs that encircle the pipe to provide superior ring stiffness and performance. It is an extruded, seamless pipe made from high grade PVC compound. Its optimized profile design offers strength and reliability, as well as economy and superior flow rates.

IPEX Ultra-Rib PVC Pipe is available in sizes 200mm, 250mm, 300mm, 375mm, 450mm, 525mm and 600mm (8" - 24").
Ultra-Rib PVC Pipe shall be made of PVC compound having a cell classification of 12454B as defined in ASTM D1784.
The pipe shall be extruded with a smooth interior and with solid reinforcing ribs on the exterior at right angles to the pipe. The space between any two ribs serves as a gasket race. Ultra-Rib PVC pipe and fittings shall be certified to CSA B182.4 “Profile (Ribbed) PVC Sewer Pipe and Fittings”, and shall meet the requirements of ASTM F794 “Standard Specification for Poly (Vinyl Chloride) (PVC) Ribbed Gravity Sanitary Pipe and Fittings Based on Controlled Inside Diameter”.
Pipe stiffness must be 320 kPa (46 lbs/in of sample length per inch of deflection) at 5% vertical deflection when tested according to ASTM D2412.
Gaskets for use with Ultra-Rib pipe are manufactured from EPDM and are designed specifically for use with Ultra-Rib pipe. This unique design is also available in Nitrile. Sealing gaskets shall meet the requirements of CSA B182.4 and ASTM F477, with the additional requirement that joints shall be able to withstand 345 kPa (50 psi) hydrostatic pressure. The joint will not leak at 10.8 psi or 25' (74 kPa) or 7.5m of head with –74 kPa (22") Hg vacuum with spigot under 5% ring deflection and joint at full axial deflection.
In the Township of Strathroy-Caradoc near London, Ontario, IPEX Ultra-Rib® was the product of choice in construction to support a boom in the township’s commercial and residential growth. Several years after installation, video inspection revealed that the system was still performing exactly as designed.
In the early 1980s, decision makers in charge of the City of Vaudreuil-Dorion infrastructures had a sense of vision and made a responsible choice for the lasting benefit of the tax payers. A vision that would ensure durable infrastructures for over 30 years. The technical services, in cooperation with the public works department, decided a major shift for products to be used in potable water distribution applications. Since then PVC has become ``The Material of Choice`` made by the City to meet the overall needs, taking into account the existing soil conditions throughout the territory.
