We are most eminent manufacturers & supplier of a comprehensive range of Expansion Bellow Joint that offers higher flexibility with zero leakage, the offered joints & bellows are manufactured at our manufacturing unit using steel wire & high strength fiber reinforcement in adherence with the set guidelines. In addition to this, the entire range of joints & bellows are passed through a series of practical tests for assuring quality.

  • Excellent strength
  • Durability
  • Superior quality

Other Details:

  • We have specialized ourselves in making of expansion joints towards following applications
  • Conveyor high temperature substances (like steam, gases etc)
  • Conveyor of high pressure or high vacuum substances
  • To absorb movements
  • To absorb vibrations (anti vibrations)
  • Noise absorption
  • Earthquake movements
  • Shock absorption
  • Very Hard 90-100°

Pressure Balanced Expansion Joints (bellows)

  • We have manufactured Expansion joints mainly for industrial piping systems to adapt movement or vibrations due to thermal and mechanical changes in the production line
  • And some of the process has wider changes in temperature hence metal components vary in size
  • Expansion joints with metal bellows are designed to absorb certain movements and minimize the conveying of forces to delicate components in the system
  • In some of the application pumps built pressure or gravity is used to move fluids through the piping system
  • Fluids under pressure follow the volume of their vessels
  • So we designed the unique concept of pressure balanced expansion joints to maintain a constant volume by having balancing bellows compensate for volume changes in the bellows (line bellows) which is moved by the pipe

Rubber Expansion Joint Bellows

  • Wrapping steel wire and fabric reinforced rubber masticated sheets
  • Rubber expansion joints are primarily manufactured by labour intensive wrapping of rubber masticated sheets and fabric reinforced rubber sheets around a bellow-shaped product mandrel tool
  • Along with rubber and fabric, reinforced rubber and/or also steel wires or metal rings are inserted for additional reinforcement
  • This can be made high pressure resistant
  • After the entire product is build up on the mandrel, it is enclosed with a winding of (nylon) peel ply to coerce all layers together before pressurization and vulcanization
  • Because of the labor-intensive production process, it takes longer

Molded Rubber Expansion Joints

  • Rubber expansion joints (some types only) can also be made with a molding process
  • They are of medium sized expansion joints with bead rings, which are manufactured in large quantities on a cylindrical mandrel, which is wrapped with partiality cut fabric ply
  • This part is finally placed in a mold and molded into shape and vulcanized
  • We manufacture for automobile sector for their bulk and faster needs
  • Our next project is to adopt new technology for robotic manufacturing of Automated winding of rubber expansion joints
