Tied Expansion Joints, Flanged

Universal Tied Expansion Joints, Flanged. Axial expansion: ±15-30, Lateral expansion: ±75-100 mm

• Two-way movements can be absorbed using the coupled expansion joints.
• Universally coupled equalizer connector consists of two spirals (bellows).
• The bellows are interconnected.
• There may also be intermediate pipe systems that can withstand the internal pressure due to the resulting traction.

Motion absorption

• This type of expansion joints are used to absorb lateral movements in all planes.
• Due to the special position of the two mounting bars at 180 degrees, the expansion joints can simultaneously absorb lateral and angular deformations.
• The size of the lateral deformation depends on the number of bellows connections on each side of the expansion joint.
• This amount can also be increased by changing the length of the intermediate pipe.
• The studs help to avoid possible twisting forces.

Advantages of Universal Attached Expansion Joints

• Absorption of lateral movements in all planes;
• Easily absorbs large expansion forces;
• Little space;
• Protects against axial inaccuracies, improves system security.
