Product Description


  • FRP Pipe with Reliable Key Lock for High Working Pressure
    Pipes are manufactured by the filament winding process.In this process the continuous fiberglass strand roving are wound onto the outside of mandrel in a predetermined pattern under controlled tension . The roving are saturated with the resin /curing agent mixture and helical wound under a calculated winding angle .
  •  
    FRP Pipe with Reliable Key Lock for High Working Pressure
  • The key lock joint is an integral joint . The spigot end has two grooves in which O-ring seals are mounted and a locking strip groove.
  •  
  • Due to the fact that the joint is restrained by a loose item , the locking strip , they key lock joint allows for an angular deflection . This type of joint is foolproof and quick to install . O-ring should be made of EPDM rubber , locking belt strip should be made from suitable grade of Nylon or glass reinforced Nylon and is shall be molded .
