Duraplus ABS is designed for industrial pressure pipe applications where the extremely high-impact resistance and ductility of the material offers some insurance against internal and external shock loadings and site abuse conditions. It’s unique combination of ABS properties – non-toxicity, purity, corrosion- and chemical-resistance, toughness, low-hydraulic resistance, and the ability to perform over a wide temperature range (-40ºF to +140ºF) ensures excellent in-service performance and system life.
Pipe and fittings shall be manufactured from a copolymeric material – Acrylonitrile Butadiene Styrene (ABS) – conforming to a 43232 cell classification in accordance with ASTM D3965.
Material for both pipe and fittings shall have a design stress of not lessthan 2,000 psi, and shall be designed with a 2 to 1 safety factor for a 50 year lifespan when operated under continuous pressure. The material shall have an izod impact resistance value of not less than 6 ft./lb. at 73ºF and 3 ft./lb. at -22ºF, when tested in accordance with ASTM D256, method ‘A’.
Pipes shall be manufactured by IPEX and designed on a Standard Dimension Ratio (SDR) basis to give various pressure ratings as described below:
Fittings shall be of the socket type, designed for solvent welding as supplied by IPEX.
Fittings shall be designed and manufactured so that they withstand the continuous pressures applicable to the maximum pressure native of the pipe.
All joints shall be made with Gray Duraplus ABS solvent cement as supplied by IPEX.
The solvent cement shall be designed to withstand continuous applied pressures up to 230 psi at 73ºF.
DESIGN AND INSTALLATION
The design and installation of ABS pressure systems shall be performed in accordance with the recommendations detailed in the Handling and Installation section of this manual, local and national regulations where applicable.
To ensure the full integrity of the completed system, all components shall be supplied by IPEX.
