What is the pressure limitation of the IPP DELTAFLEX® flange?
Most of our standard IPP DELTAFLEX® flanges have been designed to suit the ANSI B16.5 Class 150 pressure classification (275 psi operating pressure). However, many systems have been designed for higher pressures. The highest pressure to date has been Class 400 flanges, ( 990 psi operating pressure), 20″ and 34″ in size for tailings lines. We see a limitation by code set at 1000 psi operating pressure for ductile iron materials. Our largest steel pipe tailings line flange system is 48″ in diameter.
