Introduction to Horizontal Large Draw Rod Bellows Expansion Joint
The expansion joint consists of two corrugated bellows with the same geometric parameters and wave numbers connected by a middle pipe, as well as tie rods and end plates, forming a flexible component. It is primarily used to compensate for lateral displacement of single or multi-plane bending pipe sections. Suitable for "L" and "Z" type pipe systems. Due to the tie rods' ability to withstand pressure thrusts and other additional external forces, the expansion joint itself absorbs internal pressure thrusts without exerting external forces on the pipeline. Therefore, the pipeline ends of the expansion joint can utilize intermediate fixed supports or guide supports, reducing construction costs and improving efficiency.
Our horizontally mounted bellows expansion joints are designed to the high American EJMA standards, featuring excellent flexibility, corrosion and high-temperature resistance, wear and fatigue life, and the ability to absorb the axial, lateral, and angular displacements of pipelines. They have been supplied to numerous large cement plants, steel mills, power plants, and chemical factories in both domestic and international markets, ensuring stable and reliable product quality.
Performance Features of Horizontal Large Draw Rod Bellows Expansion Joint:
Two corrugated hoses connected by a middle tube, along with tie rods, end plates, and spherical-conical gaskets, form the assembly. Primarily designed to absorb lateral displacements, it can also compensate for axial, lateral, angular, and any combination of these displacements. It is recommended to install the compound tie rod type expansion joint in the middle short tube arm of a 90° Z-shaped pipeline to compensate for the axial displacement of the long pipeline ends.
Lateral displacement is the relative displacement of one end of the bellows to the other end, perpendicular to the longitudinal axis. Single-walled bellows can have lateral displacement, but the amount is very small. A good solution is to use a double-walled bellows as shown in Figure 2. The result is an increased lateral displacement compensation with reduced force.
