Spring support and hanger is a kind of supporting parts widely used in pipeline system and equipment.

Structure and composition

Spring assembly: This is the core part of the spring support hanger, usually composed of spiral spring or dish spring. Helical spring has linear elastic characteristics and can provide relatively stable elastic force within a certain load range. The dish spring has the characteristics of large carrying capacity and small deformation, which is suitable for some occasions that require high space or need to bear large loads.

Hanger body: used to connect spring components and pipes or equipment, generally made of metal materials, such as carbon steel, stainless steel, etc. It needs to have sufficient strength and stiffness to ensure reliable transfer of loads and supports.

Adjusting device: In order to adapt to different pipe installation height and load requirements, spring supports and hangers are usually equipped with adjusting devices. By rotating the adjusting nut or screw, the compression of the spring can be changed, so as to adjust the supporting force of the support hanger.

Fixed device: used to fix the spring support hanger on the building structure or other supports to ensure that the support hanger will not shift or shake during the working process. There are various forms of fixing devices, common welding type, bolt type and so on.

Function and effect

Load support: The main function is to bear the weight of the pipeline or equipment, transfer its load to the building structure or other supports, prevent the pipeline or equipment from sagging or deformation due to its own gravity, and ensure that the spatial position and direction of the pipeline system meet the design requirements.

Displacement compensation: In the pipeline system, due to thermal expansion and cold contraction, medium pressure changes and other factors, the pipeline will produce a certain displacement. The spring support hanger can automatically adjust the support force according to the displacement of the pipeline, allowing the pipeline to expand and move freely within a certain range, so as to effectively compensate the displacement of the pipeline, avoid the pipeline due to excessive binding force and excessive stress, and protect the integrity and safety of the pipeline system.

Damping buffer: It can absorb and attenuate the vibration and shock generated during the operation of the pipeline system, and reduce the harm of vibration and shock to the pipeline, equipment and building structure. Especially in some pipeline systems with fluid pulsation and mechanical vibration, the damping and buffering function of spring support hanger is particularly important.

Application scenario

Thermal pipe system: in the central heating and cooling system, the thermal pipe will produce thermal expansion and contraction with the change of medium temperature. The spring support hanger can effectively compensate the thermal displacement of the pipeline, ensure the safe and stable operation of the pipeline system, and improve the efficiency of heating and cooling.

Chemical pipeline system: Pipelines in chemical production usually transport a variety of corrosive, flammable and explosive media, and the pipeline system is complex, and the support and displacement compensation requirements of the pipeline are high. The spring support hanger can provide reliable support and displacement compensation according to the characteristics and operation requirements of the chemical pipeline to ensure the smooth progress of chemical production.

Power pipeline system: In power production enterprises such as thermal power plants and nuclear power plants, many pipeline systems such as steam pipelines and water pipelines need spring support and protection. It can ensure the safe operation of pipelines under harsh conditions such as high temperature and high pressure, and improve the reliability and safety of power production.

Air conditioning and ventilation system: In the air conditioning and ventilation system of large shopping malls, office buildings, hospitals and other buildings, the layout of pipelines is more complex, and the thermal expansion and contraction and vibration of pipelines need to be taken into account. The spring support hanger can provide good support and displacement compensation for the air conditioning ventilation pipe, reduce noise and improve the comfort of the indoor environment.
