The official website of Shanghai Songjiang Vibration Absorber Co., Ltd. presents: Bellows Compensator Installation Instructions “Simple and Practical” Information. Songjiang Group shares installation instructions for bellows compensators in both Chinese and English versions, providing convenience for users to further understand and learn about bellows compensators. Below is a detailed introduction.
Fixed Points
An expansion joint acts as a piston due to the forces generated by internal pressure. To prevent damage to the pipes, they must be properly anchored to handle these reaction forces (FR).
The formula for calculating the reaction force of an expansion joint is as follows: Fr = Q x P x 0.01 Fr = reaction force (in kN). Q = effective cross-sectional area (in cm2). P = actual pressure (in bar or kp/cm2).
Installation
Before installation, ensure that the product is used within the allowable temperature, pressure, and displacement ranges!
Expansion joints should be inspected regularly. It is recommended that expansion joints operate in compression rather than tension, and torsion and lateral displacement are not permitted.
Maintenance instructions: observe monthly whether the expansion joint is over-displaced and maintain the expansion joint within its normal length.
To ensure expansion capability, assembly bolts should be kept to a minimum (not exceeding 2 mm or 3 mm of thread depth) to avoid damaging the expansion joint body.
