Universal bellows are generally applicable to a small amount of overhead and compensation pipes, but also for the well to facilitate the detection of buried pipeline valve installation using a bellows, universal bellows can not just bury installed. Buried corrugated compensator is buried pipe to absorb the thermal deformation of the most commonly used as a preservative compensation compensation for axial compensation, the compensation capacity, but also has superior resistance to bending, can be directly used for direct burial installation . Structural differences "Buried corrugated compensator is mainly applied axial compensation, but also has superior resistance to bending, so I do not consider the impact of the pipeline sinking. Buried under the bellows housing and the guide sleeve to protect Jane achieve free expansion compensation. Other properties identical with ordinary corrugated compensator. Axial pressure bellows consists of a bellows and two end takeover constitute chemical compensation, end then take over or direct connection with the pipe flange and pipe welding, or welding flanges. Rod bellows expansion joints on the main rigid support during transport or as a product to deform adjustment, it is not a load-bearing parts. Tetrafluoroethane compensation Features (1) the compensation of thermal expansion (2) non-metallic expansion joints can be multi-dimensional direction to provide greater compensation in less size range, the compensation due to piping installation error, the system error is inevitable, nonmetallic compensator can better eliminate installation errors. (3) no reverse thrust due to the main material for the fabric compensator, unable to pass, with non-metallic compensation simplifies design. (4) high-temperature corrosion-resistant fluorine plastics used silicone material with good heat and corrosion-resistant properties. Fortunately, the sealing performance under a variety of media effect, has a good seal. Plant compensator compensator _ _ Bo-Rubber (certified merchants) by Bo-Rubber Products Co., Ltd. Hengshui.
