Customized size spring hanger mount vibration isolator for pipe connector
The variable hanger and constant spring hanger
There are two main kinds of spring hangers & supports, variable hanger and constant spring hanger. Both the variable spring hanger and constant spring hanger are widely used in the thermal power plants, nuclear power plant, petrochemical industry and other thermal-motive facilities.
Generally, the spring hangers are used to bear the load and limit the displacement & vibration of pipe system. By the difference of the spring hangers’ function, they are distinguished as displacement limitation hanger and weight loading hanger.
Normally, the spring hanger is made of three main parts, pipe connection part, middle part (mainly is the functional part), and the part which used to connect with the bearing structure.
There are lots of spring hangers and accessories based on their different functions, But main of them are variable spring hanger and constant spring hanger.
Working theory
It uses the spring to load the weight of pipe system directly. So the output load of the variable spring hanger in direct proportion to the deformation of itself.
Specification
The variable spring hanger is one kind of the weight loading hanger, and it can bear the weight and dissipate some vibration of the pipes while they have displacement in vertical direction. But the variable spring hanger will cause some additional force to the pipe system.

Constant Spring Hanger
The constant spring hanger
Working Theory
The design of constant spring hanger based on moment balance theory. It based on its smart geometric design and can keep the load moment always balanced with spring moment and keep constant support force during working situation. It can also dissipate and reduce the vibration of pipe system and will not cause any additional force to pipe system.
Specification
The constant spring hangers are used to reduce the force which caused by displacement, such s boiler body, different kinds of pipe system of power plant, and other facilities of petrochemical industry which need be supported. While if the facilities’ thermal displacement is more than 12mm and the constant spring hanger will be a better choice to avoid any dangerous bending stress and its bad transferring.
