The constant load hanger (referred to as constant support) operates on the principle of moment balance, maintaining equilibrium between load moment and spring moment within the allowed displacement range. The constant load hanger delivers a consistent supporting force during thermal expansion or contraction of pipes and equipment, preventing additional stress and ensuring long-term safe and stable operation.

Industrial Piping Systems: Supports for pipes and equipment requiring thermal displacement compensation and vibration isolation.

FAQ

Q1: How is the installation load determined for constant force disc spring supports? What should be checked after installation?

A1: The installation load is provided by the design unit based on pipeline operating conditions. The indicator plate is factory-set and locked at this load. After installation, pipeline cleaning and pressure testing must be completed before removing the upper and lower positioning blocks. Before operation, ensure all blocks are removed and the indicator plate moves freely from installation to working load. Verify that displacement under working load matches the design value.

Q2: Can the load be adjusted on site? What is the allowable adjustment range?

A2: Yes, minor on-site adjustments are allowed within ±10% of the installation load. Adjustments should be made with the pipeline in a cold state, ensuring the indicator aligns with the scale. Professional operation is recommended, and the locking mechanism should be checked after adjustment.
