Manufacturing Expansion joints (Bellows) from India

What is an expansion joint?

An Expansion Joint is used in the piping system to absorb thermal expansion or terminal movement, where the use of an expansion loop is impractical. Expansion joints are in different shapes and materials. Expansion joints are rubber, metallic, Teflon joints

Where are Bellows used?

Bellows are located between the section of bridges, paving slabs, railway tracks, and piping system. The Expansion joints are incorporated to endure the stress

Why expansion joints are used?

Expansion joints are used to absorb the thermal expansion. They also can be used to absorb contraction in the cryogenic line and reduce the vibration in the piping system. They are nessccary in the system to convey high-temperature substances such as steam or exhaust gases or to absorb movement and vibration.

How do you install expansion bellows in a pipe system?

Apply Lubricant
Insert expansion joints into position
Insert Bolts
Control Rods

Gimbal Expansion Joint

What is Gimbal Expansion Joint? Design to absorb the system thurst and torsional twist while allowing angulation in any plane. This is a single expansion joint designed to permit angular rotation in any plane by the use of two pairs of hinges affixed to common floating gimbal ring. Gimbal Expansion Joint Double Bellows Gimbal Expansion Joints with weld ends Gimbal Expansion Joints are used to absorb angular rotation in any plane direction, using two pairs of hinges attached to a common floating gimbal ring. This type of construction provides a close control over the movement imposed up on the bellows and also supports the dead weight of the pipe. The wind and shear loads are also taken care of by the gimbal structure. Gimbal bellows joints are designed to absorb the full pressure thrust load of the expansion joint and thus guard the adjacent equipment from damage due to thrust loading. Gimbal bellows joints are not limited to a single plane, they provide greater usability. Gimb...

Externally Pressurized Expansion Joint | Flexpert Bellows

Externally Pressurized Expansion Joint Externally Pressurized Expansion Joint is the perfect solution when the expansion joint must absorb large axial movement under High Pressure. Externally Pressurized Expansion Joints Absorbs large axial movements without squirm. Eliminates main anchors. Minimum guiding required for externally pressurized expansion joints Heavy duty construction for bellow protection. The Externally Pressurized Expansion Joints provide very low turbulence to f the flowing medium due to the fact that the internal surface of pipeline itself works as the liner for this expansion joint. As the thermal expansion in externally pressurized expansion joints occur the bellows element brining the internal guide rings closer reducing the gap between them and then medium can flow through this joints as if it were not there.
