Pressure Balance Bellow
VIEW DETAILS
The buried type rubber expansion joints are designed for underground installation and absorb the movement of piping lines. It is used for raw water supply pipe lines, water treatment plant and drainage system line, etc.It absorbs movements in angular and lateral direction and provides a solution for broken piping lines, leakage or bending caused by earthquake, temperature difference, geology tenderness and exterior impact, etc.
Buried Type Expansion Joint
VIEW DETAILS
Pressure balanced expansion joint is used most frequently in applications similar to those shown for the single expansion joint, but where pressure loading up on piping or equipment is considered excessive or objectionable. The major advantage of the pressure balanced design is its ability to absorb externally imposed axial movement without imposing pressure loading on the system.Where large amounts of lateral deflection are involved, a pressure balanced universal expansion joint must be used. Two bellows are used in the flow end of the expansion joint and a single bellows in the balancing end. Normally, the balancing bellows will be subjected only to axial movement if the tie rods are properly designed to rotate or pivot at their attachment points.Features:· Absorbs axial and lateral movements· Eliminates main anchors· Pressure forces remain in balance· No volume change· Balance pressure thrust remains constantTypes of Movement:· Axial compression or extension· Lateral movements· Angular rotation

Molded type expansion joints incorporate the movement and vibration dampening capability of a spool joint into a compact and robust device.Molded type expansion joints are available in several sizes and variations. The distinguishing features of the spherical joints are the shape of the body, floating flanges and the beaded seal. The more common configurations include the single sphere, double sphere and double sphere union. The double sphere is for applications requiring greater movement than a single sphere, while double sphere unions are installed in smaller-sized threaded pipe applications.
Molded Expansion Joint
VIEW DETAILS
Expansion bellows can be designed with reinforcing or equalizing rings which are located around the outside of the convolutions, preventing bellows being forced out from high pressure. The principal purpose of these devices is to reinforce the bellows under internal high pressure, so that bellows does not squirm and equalize movement among all the convolutions.Equalizing and reinforcing rings are made of carbon steel, stainless steel or other suitable alloys.Reinforcing rings are usually Tee shaped in cross section and equalizing rings are normally fabricated from tubing or solid round bars of suitable material.Bellows with reinforcing or equalizing rings can be made for any type of expansion joint (axial, lateral or angular etc.). The disadvantage of these bellows is the increased stiffness and limited movement of the bellows.
High Pressure Type Metallic Expansion Joint
VIEW DETAILS
PTFE lined are extremely low co-efficient of friction and resistance to practically all corrosive fluids and forms of chemical attack.PTFE lined are widely used in chemical plants and other piping applications where acids and highly corrosive chemicals are being handled.PTFE bellows come into their own for corrosive, high purity or hot applications. These have been independently tested by the internationally recognized safety and quality group for both traditional short term bench mark performance testing and innovative long term pressure increase testing.PTFE bellows and PTFE expansion joint combine the high corrosion resistance of PTFE and its flexion capability.Based on these two properties of PTFE, products are suitable for use with all chemical products and compensate for repeated thermal expansion in pipelines. They are also widely used to protect equipment against vibration and piping loads.
PTFE Line Metallic Expansion Joint
VIEW DETAILS
A single expansion joint is designed to permit angular rotation in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring.Unlike the hinged joint, which can absorb angular rotation in a single plane only, the gimbal joint can absorb angular rotation in any plane. The ability of the gimbal expansion joint to absorb angular rotation in any plane is most often applied by using two gimbal joints which act together to absorb movement. Gimbals, like hinges, are designed to transmit the pressure thrust and are used in pairs, or in conjunction with a hinged joint. A gimbal ring is either round or square. For round gimbals the torsional moment shall be considered and for square gimbals the instability due to the bending shall be considered.Features:· Absorbs angular rotation and low forces on piping system· Withstand pressure thrust load and no main anchors required· Transmits shear loads and prevents torsion on bellowsTypes of Movement:· Angular rotation in any plane
Single Gimbal Type Expansion Joint Bellow
VIEW DETAILS
Double hinged expansion joint consists of two single hinged expansion joints connected with intermediate pipe with double hinge restraints to absorb pressure thrust, axial force due to the effect of pressure. Therefore, any expansion of the center pipe within the limits of the hinge bar will simply compress the bellows, and will not exert movement on the adjoining pipe. Application of this expansion joint is for compensating large lateral movement.Features:· Angular motion in one plane· Eliminates pressure thrust load· Prevents torsion on bellows· Low forces on piping systemTypes of Movement:· Angular rotation in a single plane
Double Hinged Type Expansion Joint
VIEW DETAILS
A single hinged expansion joint is designed to permit angular rotation in one plane, by the use of a pair of pins through hinge plates attached to the expansion joint ends.Hinged joints are used in sets of two or three, to absorb pipe movement in one or more directions in a single plane piping system.Expansion joint hinges are designed to transmit the full pressure thrust of the expansion joint. A hinged system permits large movements to be absorbed with minimal anchor forces.These units do not allow axial movement however, some types of hinge systems can be provided with holes for the hinge pin that are slotted to allow limited axial displacement. These slotted hinge types cannot resist the pressure thrust forces and therefore proper anchorage must be provided.Features:· Angular motion in one plane· Withstand pressure thrust load· Prevents torsion on bellows· Low forces on piping systemTypes of Movement:· Angular rotation in a single plane· Allow limited axial displacement with slotted hole
Single Hinged Type Expansion Joint
VIEW DETAILS
Universal tied expansion joints contain two bellows separated by a pipe spool with tie rods designed to withstand the pressure thrust force. These expansion joints are generally designed to accommodate lateral movement only. A universal expansion joint can be designed to have a very low lateral spring force to minimize forces on adjacent equipment. Large offset movements are possible in a universal assembly by increasing the distance between the two bellows. A two tie rod design can also accept angular deflection in a single plane.Features:· Absorbs large amounts of lateral movement· Unit length does not change with thermal expansion· Withstand the pressure thrust forceTypes of Movement:· Large lateral deflection· Angular rotation
Universal Tied Type Expansion Joint
VIEW DETAILS
This expansion joint has two bellows sections connected by a center pipe section. This design allows for large amounts of lateral deflection. The universal can also allow for axial and angular movements in addition to the lateral movement. This expansion joint does not come with the hardware to resist pressure thrust. Like the single unrestrained expansion joint the universal expansion joint must be properly anchored and supported.Universal unrestrained expansion joint is appropriate for any application where pressure thrust can be handled by external anchorage. The universal unrestrained expansion joint is appropriate for large lateral offset requirements wherever a low lateral offset spring rates is required.Features:· Simple design and relatively low cost· Suitable for a low lateral spring rate and high lateral movement· Use of tie rods can resist pressure thrust.· Requires main and directional anchors and guideTypes of Movement:· Axial movement· Large lateral deflection· Angular rotation
