Pressure Balanced & Universal Expansion Joints

Metal Expansion Joints

Metal Expansion Joint

Silverfox can custom design and supply various types of expansion joints based on

your needs and requirements of the system. Some commonly used expansion joints are:

Universal Expansion Joint

Universal expansion joints are used where axial movement is larger than can be absorbed by a single

expansion joint. The universal expansion joint assembly consists of two single expansion bellows

connected by intermediate pipe. Universal expansion joints can also be used used where large amount

of movement in any combination (axial, lateral and angular rotation) is required which cannot be absorbed by a

single expansion joint.

 

Piping Expansion Joints

Pressure Balanced Expansion Joint

Elbow Pressure Balanced expansion joints are designed to absorb axial and /or lateral deflection

while continuously restraining the pressure force. Balance (out of line) bellows creates an equal

and opposite force to the working (in line) bellows The typical arrangement as shown is to have a

balance side and a working side separated by an elbowed mid-section. Tie rods are used to

balance and restrain pressure forces.

Arch Type:

A full face integral flange design is available in both Single Arch and Multiple Arch Types expansion joints. These basic types can be manufactured to meet requirements of ASTM F1123-87. These types of expansion joints are available in several construction design series, based on the application pressure requirements.

Single Narrow Arch Type.

Construction is of fabric and rubber, reinforced with metal rings or wire. The full face flanges are integral with the body of the expansion joint and drilled to conform to the bolt pattern of the companion metal/FRP flanges of the pipeline. This type of rubber expansion joint face flange is of sufficient thickness to form a tight seal against the metal/FRP flanges without the use of gaskets. The shortest rubber expansion joint face to face dimensions are available with this type of rubber expansion joint construction.

Metal Expansion Joints – Types of End Conections

Posted by . In Metal Expansion Joints | Comments Off on Metal Expansion Joints – Types of End Conections

 

There are various end connections for Metal Expansion Joints to suit your application.These types of metal expansion joint end connections are:

Flanges – including special flanges, slip on or angle flanges to suit any standatd or non standard drill pattern.

Metal Bellows

Vanstone Ends – are modofied flanged ends with the added flexibility in resolving bolt-hole misalignment.

Metal Bellow Vanstone Ends

Weld Ends – allows any pipe or duct to be attached to a expansion joint for welding into a pipe system.
