Directly buried bellows compensator, also known as buried compensator, is mainly applicable to the axial compensation of directly buried pipelines, and has the ability of bending, so the influence of pipeline sinking is not considered. Need to pay attention to when using the buried corrugated pipe compensator requires only a ripple compensator is arranged between the two fixed bearing, calculation and single corrugated compensator of the compensator on bearing force calculation of bearing force is the same as that of the direct buried corrugated pipe compensator to achieve free compensation and simple installation in the pipeline, and thus by the engineering design and the installation of users welcome.
The bellows with high fatigue limit of 1Cr18Ni9Ti stainless steel (steel plate thickness 0.2~10mm), suitable for installation of pipe diameter for weak corrosive medium DN100~600mm in the temperature below 350 DEG C, working pressure 0.25~25MPa, nominal. But the most used is PN0.2, 0.5, 1.0MPa three levels, pipe diameter DN50~500mm pipeline engineering. In order to reduce the flow resistance, reduce erosion phenomenon under high velocity flow, or to reduce the resonance due to ripple occurs, when the nominal diameter is larger than 150mm, DN and steam (gas) flow or liquid flow rate of V v=8m/s is greater than or equal to 3m/s, should be used with an inner sleeve compensator.
