The Series 7200 Super Flange® is a restrained flange adapter designed to connect plain end pipe to a flange end component. May be installed on ductile iron, steel, PVC, PVCO and HDPE pipe.
File Type
Restrainer mechanism shall be integrated into the design of the restraint gland. As the mechanism is activated, multiple wedging action shall be imparted against the pipe increasing its resistance as internal pressure increases. After burial of the restraining mechanism, joint flexibility shall be maintained.
The actuating bolt shall be threaded into the gland and have a 1-1/4″ hex operating nut. The actuating bolt system shall have a torque-limiting head designed to break off at preset torque levels, thus insuring proper action of the restraining device. After removal of the torque-limiting head, a 5/8″ hex head shall remain to facilitate the removal and re-assembly of the gland. Glands, bolts and wedges shall be manufactured of high strength ductile iron in accordance with ASTM A536 Grade 65-45-12 requirements. Wedges shall be heat treated to a minimum hardness of 370 BHN.
All internal and external surfaces of flange adapter ring will have fusion bonded epoxy per requirements of ANSI/AWWA C116/A 21.16. Coatings and gaskets to meet ANSI/NSF-61. The restraint mechanism shall have a 2:1 safety factor for pressure rating as stated in the most recent catalog.
