Buried external pressure bellows

Buried compensator with external pressure compensator and free compensation Buried compensator double bit, to heat network is widely used in road construction. Buried compensator (stainless steel bellows) chosen for the same freedom to install and compensation Buried bellows compensation, related to external pressure bellows compensator parameters reference sample axial external pressure stainless steel bellows have all data. Features: bellows compensator at both ends of the outer tube, respectively, through tube connected Compensation Features: The compensator can absorb a large axial displacement. Buried external pressure bellows instructions: Buried external pressure bellows mainly applied axial compensation, but also has superior resistance to bending, so I do not consider the impact of the pipeline sinking. Freedom telescopic compensation Buried under external pressure bellows housing and the guide sleeve is protected, other properties and the same common bellows.
