Tank Fittings, Flanges, Flanged Nozzles
The Pad Flange
The Pad Flange is the perfect answer to drain any cone bottom tank. Cone bottom tank stands usually allow a standard of 12" for piping clearance. This helps keep the overall height of the tank down, but also makes using large pipes very difficult. Our Pad Flange can be constructed in any applicable size and only projects 1" off of the lowest surface of your tank. The Pad Flange features corrosion resistant thread inserts, a Full raised face design, and a internal/external heavy duty seal. Specifically designed for cone bottom tanks, this fitting is a perfect accessory for any mixing application.
The “Raised Face WFN™ - the most advanced polyethylene fitting on the market
The all new Raised Face WFN™ incorporates the heavy duty 1” thick face, heavy wall pipe construction, and expert welding used on the Super Flanged Nozzle with a full contact raised face design. Now you can have all the chemical resistance and versatility of a polyethylene flange combined with the sealing power of a raised face. This flange has been shop tested for pull out exceeding 2,700 lbs, rated for 25 psi @ 10 ft lbs of torque, and shop tested to over 100 psi @ 10 ft lbs of torque.
This fitting comes in all of our standard sizes (2,3,4,6,8,10,12,16). It can be made black for further UV protection, and the face can be made thicker for further stability. It can be located almost anywhere on your HDLPE tank giving you more flexibility in piping.
The Raised Face WFN™ is the “drip stopping” solution you’ve been seeking.
