Product Profile of Industrial Grade Expansion Joints

Industrial Grade Expansion Joints consist of two bellows elements joined together by a common spool piece so it is also called as double bellows expansion joint or universal bellows. The Joints are capable of absorbing axial movement, lateral deflection and angular rotation or any combination of these. The Joints have the feature that the amount of lateral deflection that can be absorbed by a double bellows expansion joint is directly proportional to the length of the spool piece between the two bellows elements. The Industrial Grade Expansion Joints exerts a thrust force on the anchors adjacent equipments as a result of pressure.

Key Features of Industrial Grade Expansion Joints

• Consist of two bellows elements joined together by a common spool piece so it is also called as double bellows expansion joint or universal bellows.
• Capable of absorbing axial movement, lateral deflection and angular rotation or any combination of these.
• The amount of lateral deflection that can be absorbed by a double bellows expansion joint is directly proportional to the length of the spool piece between the two bellows elements.
• Exerts a thrust force on the anchors adjacent equipments as a result of pressure.
• This force is equal to the mean effective area of the bellows times the internal pressure.
• There are no tie rods in this expansion joints to absorb the pressure thrust it must be entirely absorbed by the anchors.
• Due to lack of tie rods and the nature of these joints to impose the thrust loads on the anchors, double bellows expansion joints are mainly restricted to low or moderate operation.
• Designed to withstand the full thrust forces.
• Absorbs large axial movements, lateral deflection and angular rotations, or any combinations of these
• No change in flow direction required for installation
