Tied Expansion Joints
- Use tie rods to restrain axial movement and absorb pressure thrust internally eliminating the need for anchors to handle pressure thrust forces.
- At LSI – MECH, we have in-house expertise to design and engineer tie rods that ensure reliable performance under thermal, pressure, and mechanical loads.
Tied Single Expansion Joints
- One bellows with tie rods
- Handles small lateral movement only
- Suitable for short pipe runs with minor misalignment
Tied Universal Expansion Joint
- Two bellows connected by a centre spool
- Absorbs large lateral, moderate axial, and angular movement
- Ideal for systems requiring multi-directional flexibility
These expansion joints are used in power generation, refineries, HVAC, and other industrial piping systems where pressure control and movement absorption are critical. For how this bellows work go to animation section
