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 performs other industry options such as 140 BHN for 316 SS and 180 BHN for cast grey iron.
PERMA/flo elbows are available in one piece IWB (Integral Wear back) and two piece RWB (Removable Wear back) designs.
​
PERMA/flo Pipe & fittings are joined together with the use of compression couplings or flanged adapter assemblies. Couplings allow for minor thermal expansion and alignment, providing up to 4 degree deflection while the flanged adapter allows you to connect to ANSI Round Bolt patterns
