Chemical Process Piping AlphaPlus PP and Kynar® 740 PVDF Piping Systems Simtech offers two outstanding, stress-relieved piping systems (AlphaPlus PP and Kynar® 740 PVDF) and fittings to handle a wide range of industrial pressure piping applications. Our unique inline annealing process results in a stress-relieved product that exhibits superior chemical resistance, reduces stress cracking, and provides greater impact resistance when compared to other PP and PVDF. AlphaPlus PP is compatible with a broader range of chemicals than other piping materials such as FRP and Corzan® CPVC, and handles temperature ranges from 35°F-200°F. Kynar® 740 PVDF has outstanding chemical resistance to highly aggressive inorganic chemicals, acids, hydrocarbons and halogens, handles temperature ranges from -40°F-280°F and is an ideal substitute for exotic alloys. Both systems outperform and offer significant cost savings when compared to Corzan® CPVC, FRP, lined steel, and exotic alloys.
