Product Description

The lateral small bolt bellows expansion joint is a flexible component composed of two bellows with the same geometric parameters and wave numbers connected by a middle tube, as well as small bolts and end plates. Our company's lateral small bolt bellows expansion joints are designed with high optimization following the American EJMA standard, featuring good flexibility, corrosion resistance, high-temperature resistance, wear resistance, and long fatigue life. They can absorb the axial, lateral, and angular displacements of the pipeline. They have been supplied to numerous large-scale cement plants, steel mills, power plants, chemical factories, and key enterprises in various industries at home and abroad, with stable and reliable product quality.

Lateral displacement is the relative displacement between the ends of a bellows in the direction perpendicular to the longitudinal axis. Single-bellows can have lateral displacement, but the amount is very small. A good solution is to use a compound bellows as shown in Figure 2. This results in an increased lateral displacement compensation and reduced force.

The application range of horizontal small pull rod bellows expansion joints: Widely used in power plants, water treatment plants, sewage treatment equipment factories, chemical plants, cement plants, etc., examples of product applications:
