Compensators are also traditionally referred to as expansion joints. They consist of bellows.(A type of elastic element)Consisting of the attached components, the bellows is the main working body. The attachments include end pipes, brackets, flanges, and conduits. It is a type of compensating element. The effective expansion and contraction deformation of the bellows working body is used to absorb size changes in pipes, conduits, and vessels due to thermal expansion and contraction, or to compensate for their axial, lateral, and angular displacements. It can also be used for noise reduction and vibration damping.
Bellows are widely used in modern industry. In heating systems, to prevent deformation or damage to heating pipes caused by thermal expansion or temperature stress, compensators need to be installed on the pipes to compensate for the thermal expansion, thereby reducing the stress on the pipe walls and the force exerted on valve or bracket structures.
Compensators feature rectangular cross-sections and circular bellows, with each individual expansion joint in the pipeline accommodating two-dimensional displacements. Elbows composed of two expansion joints can withstand three-dimensional displacements. Rectangular-circular metal bellows compensators are available in full-height and half-height options. Users can select multiple sections based on flue dimensions and stress-strain requirements.
1.After selecting the appropriate compensator based on the thermal displacement of the pipeline system, the user must at least provide the circulating medium in the pipeline, the design pressure of the flue gas pipeline, the temperature during operation, and the total dimensions of the cross-section of the flue gas pipeline.(Length and width)The selected waveform(Full Height216mmHalf-height108mm)With wave numbers(Single wave number does not exceed6Bo (留空，没有提供具体内容))To facilitate the design and manufacturing of the compensator structure.
2.Each wave allows for expansion amount:Full Height △ α= 24 mmHalf-height model △ α= 12 mm。
3.Dust shield:Dust-free ductwork or pipes must be used; for those with high dust content, dust baffles should be employed.
4.To reduce the number of nodes in the bellows, it should be considered that...50Cold Drawn.
5.The compensator is suitable for cross-sectional areas less than4.6Square meters, flue exterior dimension on one side less than1.5Millet but larger0.6Millimeter situations..Standard full height corrugated compensators are suitable for all flue and air ducts.
