Metal bellows

Double lever corrugated expansion joint

Horizontal large rod bellows expansion joint profile

he expansion joint is a flexible component composed of two corrugated pipes, tie rods and end plates connected by the middle pipe with the same geometric parameters and wave numbers。 It is mainly used to compensate the lateral displacement of a single-plane or multi-plane curved pipe section。 Suitable for "L" type and "Z" type piping。 Because the pull rod can withstand the pressure thrust force and other additional external forces, the expansion joint itself absorbs the internal pressure thrust and does not generate external force on the pipeline。 Therefore, intermediate expansion brackets or guide brackets can be used at both ends of the expansion joint to reduce the construction cost and improve the construction efficiency。 。


The transverse large rod corrugated expansion joint manufactured by our company is optimized by the high US EJMA standard, featuring good flexibility, corrosion resistance, high temperature resistance, wear resistance and long fatigue life, and can absorb the axial, lateral and angular displacement of the pipeline. . Has been for many domestic and foreign large-scale cement plants, steel mills, power plants, chemical plants and other key industries supporting enterprises, product quality is stable and reliable.


Horizontal large rod bellows expansion joint performance characteristics:


It is composed of two bellows connected by the middle pipe and structural members such as tie rods, end plates, spherical and taper washers. It mainly absorbs lateral displacements, and can also be used to compensate for axial, transverse, angular and synthetic forms of these three types. Displacement in any direction. It is recommended to install a double lever type expansion joint in the middle short pipe arm of a 90° Z-shaped pipe to compensate for axial displacement of the long pipeline at both ends.

The lateral displacement is the relative displacement in the vertical direction of one end of the bellows and the longitudinal axis of the other end. Single bellows can have lateral displacement, but the displacement is very small. A good solution is to take the double bellows as shown in figure 2。 As a result, the lateral displacement compensation amount increases and the force decreases。

Horizontal large rod bellows expansion joint application range: Mainly used in "L" type and "Z" type piping systems
