PPDI - ANSI B16.5 Class 150, ID Metric

ANSI B16.5 Polypropylene Encapsulated Ductile Iron Flange

Stu Piping manufactures and supplies the PPDI flange, drilled to ANSI B16.5 for use in North American and internationally ANSI-standardized piping systems. Built with a glass fibre reinforced polypropylene encapsulation over a ductile iron core, the PPDI flange delivers corrosion resistance and weight savings for PE, PP, and PVDF stub end applications.

Ideal Applications for the PPDI ANSI Flange

Aquaculture / fish farm piping systems
Water infrastructure and treatment
Mining piping systems
Gas piping applications
Marine piping installations
