The need for a durable and cost-efficient pipe rehabilitation solution has never been more paramount. The engineers at IPEX recognized this need and have responded with NovaForm™ PVC Liner, a product that brings the lasting benefits of factory-made PVC pipe to the North American trenchless pipe rehabilitation industry.
NovaForm™ PVC Liner is used in sewer and culvert rehabilitation. Extruded and
coiled onto reels, the product is heated and conditioned at the job site, then
pulled into an existing sewer or culvert by mechanical means. The NovaForm
Liner is plugged and expanded by introducing steam and then air, allowing it to
form snuggly against the host pipe. As air is introduced, the pipe cools and
hardens producing a fully functional pipe.
Size Range 6" – 30" (150mm – 750mm)
ASTM F19 47
This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, marking and packaging.
The pipe shall be made from PVC compound meeting all the requirements for cell classification 12334 as defined in specification D1784 and with minimum flexural modulus properties, tested as per ASTM Method D790, of 320,000psi (2,200MPa).
There shall be no evidence of splitting, cracking or breaking when the rounded pipe is tested according to section 11.3 of ASTM F1504.
Pipe Impact Strength
The impact strength of rounded pipe shall not be less than the values in Table 1 when tested in accordance with test method D2444 as referenced in ASTM F1504.

The extrusion quality of the pipe shall be evaluated by the following test methods:
Acetone Immersion: The pipe shall not flake or disintegrate when tested in accordance with test method D2152 as referenced in ASTM F1504.
Heat Reversion: The extrusion quality of the pipe shall be estimated by heat reversion method in accordance with practice F1057 as referenced in ASTM F1504.
Flexural Properties: The flexural strength and modulus of the pipe shall be tested in accordance with test method D790 as referenced in ASTM F1504.
Rounded Pipe Diameter: The average outside diameter of the formed pipe shall meet requirements in Table 3, +/- 1.0% when tested in accordance with test method D2122 as referenced in ASTM F1504.
Rounded Pipe Wall Thickness: The wall thickness of the formed pipe shall not be less than the values specified in Table 3 when tested in accordance with test method D2122 as referenced in ASTM F1504.

24 (600) 0.34 (8.7)
30 (750) 0.43 (10.8)
Workmanship, Finish, and Appearance
The rounded and folded pipes shall be homogeneous throughout and free from visible cracks, holes, foreign inclusions, or other defects. The pipe shall be as uniform as commercially possible in colour, opacity, density and other physical properties.
Pipe shall be clearly marked as follows at intervals of 5ft. (1.5m) or less:
- Manufacturer’s name or trademark and code
- Nominal outside diameter
- The PVC cell classification, for example “12334”
- The legend “DR XX FOLDED PVC PIPE”
- The designation “Specification ASTM F1504”
- Length marker and liner distance label, for example “100FT” (“30.5M”)
The full length of the PVC pipe is coiled onto a reel in a continuous length for storage and shipment. The minimum diameter of the reel drum or core shall be 48in (1,219mm).
When the product is marked with ASTM F1504 designation, the manufacturer affirms that the product was manufactured, inspected, sampled and tested in accordance with the specification and has been found to meet the requirement of it.
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.
