» Pressurebalance Bellows ::..
This type of Bellow Expansion Joints is normally used where a change of direction occurs in a run of piping and pressure thrust to be absorbed.
   
  Top
 » Universal Gimbal Bellows ::..
This type of Expansion joints is used to thermal movement absorption in multi plane direction of piping.
   
  Top
 » Inline Pressure balanced Expansion Bellows ::..

A constant volume arrangement created by two balancing bellows whose difference in cross sectional area is twice that of the in-line bellows thus by eliminating pressure-thrust without change in direction.
