Product Description

Constant Force Pipe Spring Support and Hanger

The Constant Force Spring Supports (Constant Supports) provide a constant supporting force through the total travel of the support. The simplified construction, together with the compression spring working in conjunction with a bell crank lever, achieves a mathematically perfect counter-balancing of spring and load moments about the main pivot point.

Constant Load Spring Supports are typically used when large vertical movements are present in critical piping to avoid the transfer of residual stresses to other process piping systems.

Key Advantages

✔ Five travel ranges from 0 to 400 mm / 0 to 15.75 in, load group C to load group 9.

✔ Torque-free load application by covering the load and symmetry axis.

✔ Favourable power-weight ratios for reduced installation loads.

✔ Modular system simplifies selection (load groups and travel ranges).

✔ Readily adaptable to installation situations due to standardised accessories.

✔ Secure connection of load chains due to load-compatible modular components.

Frequently Asked Questions

What is the main function of a Constant Force Spring Support?

The primary function is to provide a constant supporting force throughout the full range of vertical movement in a piping system, preventing the transfer of stresses to other components.

What standards do these hangers comply with?

Our spring supports and hangers are designed and manufactured in accordance with ASME standards and ISO/GB specifications.

In which industries are these spring supports commonly used?

They are widely applied in Oil, Gas, LNG facilities, Metallurgy, Refineries, and Power Plants where critical piping systems are present.

What is the available displacement range for the JN-PS02 model?

The displacement range is typically between 60mm and 400mm, though custom requirements can be accommodated.

What temperature range can these supports withstand?

They are designed to operate effectively in temperatures ranging from -20°C to +200°C.

What are the load variations for these hangers?

The constant rate is maintained within ≤3%, and the load difference is kept within ≤5% to ensure stability and safety.
