Features
- Consisting of two bellows are separated by an intermediate pipeline universal compensator.
Used for absorbing large lateral movements. - In general, after crossing points on the basis of buildings with different floor exercises and building collapses it is used to prevent damage to the existing pipeline.
- The expansion joint allows large lateral movement in all planes, this movement can be increased by increasing the length of the central pipe.
- Can take greater axial, lateral and angular movements than a single tied expansion joint.
- If the universal tied expansion joint is designed with only two tie rods, equally spaced @ 180 degree, the expansion joint will take both lateral and angular movements.
- To restrict the angular movement, four tie rods are provided at in interval of 90 degrees, around the circumference of the expansion joint.
- If more than two tie rods are used then this kind of expansion joint will only take lateral movement.
- Generally used in transition points of the buildings which has different base levels, in ground movements and to avoid pipeline damages after building collapses.
- Usually are provided with control rods to distribute the movement equally between the two bellows.
- Control rods are not designed to withstand pressure thrust.
- Can be manufactured in flanged type (FAF5410) and welding netype (FAF5420)
- Stock piled for quick delivery.
