Restrained Flexible Weld Bead Joint  (RFWB) 'Ve' Type


Suitable for unstable ground conditions like marshy ground, subsidence areas, seismic zones, Hilly terrains, limited accessibility areas (insert sectional diagram of joint and let text go around it)

Available in sizes ranging DN 80 to DN 1000 mm, the RFWB joint adopted by Electrosteel for restraining involves a weld bead at the spigot end, glands, locking ring and bolts & nuts. The nature of the joint is such that it retains the flexibility associated with the normal push fit joint system. The gland and locking ring, connected to the socket collar by bolts & nuts, create the restraining force against the weld bead of the spigot.
