Delta Ducon PERMA/flo pipe & fittings are designed to withstand the wearing action of abrasive materials when transported either hydraulically or pneumatically.
PERMA/flo Pipe & Fittings are cast of proprietary iron alloys that produce hardness ranges up to 550 BHN (Brinell Hardness Number). PERMA/flo out preforms other industry options such as 316 SS (140 BHN) and cast grey iron (180 BHN).
PERMA/flo Pipe & Fittings are joined together with the use of compression couplings. Couplings allow for minor thermal expansion and alignment, providing up to 4 degree deflection. Flange adaptors are available when flanged connections are needed.
PERMA/flo fitting are available in an extra thick Integral Wear Back (IWB) design and a Removable Wear Back (RWB) design.
