Ductile Iron Pipes - Boltless Restrained Joint (Electrolock Joint)

Features

  • Can withstand very high pressure
  • Needs factory manufactured long socket pipes with two chambers – one for sealing and the other for restraining axial movement
  • The water sealing is done by Push-on gasket and restraining is done by Weld Bead and Locking Bar
  • Normal Push-on joint gasket is to be used for sealing
  • After assembly, the locking bars in parts are inserted in the Locking Chamber. The weld bead on the spigot gets locked with the locking bar against separation force
  • Can be used for trenchless applications where all pipes with such joints are used in the trenchless portion
  • Easy to assemble and disassemble when required
