Tetrafluoride compensator is also called expansion joint or expansion joint. The utility model is composed of a bellows (an elastic element) constituting the main body of the bellows and accessories such as an end pipe, a bracket, a flange, a conduit, etc. The utility model belongs to a compensation element. Tetrafluoride compensator uses the effective expansion deformation of bellows of its main body to absorb the size changes of pipelines, conduits, containers caused by thermal expansion and contraction, or to compensate the axial, lateral and angular displacements of pipelines, conduits and containers.

The function of tetrafluoro compensator:

1. Tetrafluoride compensator mainly compensates the cold and hot deformation of absorption pipeline in the axial, transverse and angular directions.

2. Tetrafluoride compensator is mainly expansion, which is convenient for installation and disassembly of valve and pipeline.

3. Tetrafluoride compensator mainly absorbs the vibration of equipment and reduces the influence of equipment vibration on pipeline.

4. Tetrafluoride compensator mainly absorbs the deformation of pipeline caused by earthquake and subsidence.

Polytetrafluoroethylene bellows compensator (also known as expansion joint) is used to compensate the displacement and installation deviation of thermal expansion and contraction in pipeline system with strong corrosive medium, and reduce the vibration of pipeline system.

Tetrafluoro compensator has a strong reliability, based on many customers have their concerns about what aspects of reliability, the following company on its reliability to you to make an explanation.

The reliability of tetrafluoro compensator is composed of design, manufacture, installation and operation management. Reliability should also be considered from these aspects. For the choice of materials, we will make a detailed introduction:

Material selection for bellows used in heating network should take into account not only working medium, working temperature and external environment, but also the possibility of stress corrosion, the influence of water treatment agent and pipeline cleaning agent on materials. On this basis, the welding, shaping of bellows and the performance-price ratio of materials should be combined. The economical and practical material of corrugated pipe is selected.

Generally, the material of bellows should satisfy the following conditions:

(1) High elastic limit, tensile strength and fatigue strength to ensure the normal operation of bellows;

(2) Good plasticity makes it easy for bellows to be machined and formed, and sufficient hardness and strength can be obtained by subsequent treatment processes (cold work hardening, heat treatment, etc.).

(3) Good corrosion resistance to meet the working requirements of bellows in different environments;

(4) Good welding performance to meet the welding process requirements of bellows in the manufacturing process.
