Axial external pressure compensator belongs to a compensation components. Using their body of work stretching deformation effective bellows to absorb axial pipelines, conduits, containers, etc. Dimensional changes caused by thermal expansion and contraction and other reasons arising from, or compensate for pipelines, conduits, containers, etc., lateral and angular displacement. It can also be used for noise damping. Widely used in modern industry. Axial external pressure compensator advanced design, reasonable structure, lightweight compensation, easy handling, resistant to high and low temperature, high pressure, corrosion resistance, fatigue resistance and other characteristics. In addition to external pressure axial compensator also has an absorption axial displacement, with a large amount of compensation, good insulation properties, the residual medium can be ruled out and so on. Axial external pressure compensator is widely used in petroleum, chemical, steel, metallurgy, machinery, transportation, transport, ship, dock, construction, rubber, paper, textile, electric power heating network, pharmaceutical, medical and other industries. Unconstrained bellows compensator within a single layer, double layer or multi-layer U-shaped wave, bellows and diversion units 1Cr18Ni9Ti austenitic stainless steel materials, other materials for the low-carbon steel or low alloy steel. Unconstrained compensator in the mounting bracket spacing is determined and fixed bearing calculation and the general thrust of axial compensator identical. In order to make the project a stable and reliable, non-binding compensator addition to the requirements close to the fixed bracket, but still requires that each mounting bracket features three guide bracket spacing. Unconstrained compensator completely eliminates L1≤4D, L≤14D and L3 requirements of conventional axial compensator guide bracket spacing to achieve a pipe rack spacing "unconstrained" final goal. Unconstrained compensator not only has a columnar stability, but also has a self-steering capability within the axial pressure bellows completely eliminate 4D, 14D, L3 constraints, to overcome the installation error straight pipe pressure balanced bellows (ZYP, small size, safe and reliable, but also can eliminate the conventional axial compensator prone to twist and instability and other common diseases, and pipe insulation has brought great convenience. Unconstrained compensator to compensate for axial pipe universal hinge bellows, large amount of compensation, with a strong self-steering and superior bending resistance, which can simplify pipe guide bracket is designed so that the installation guide bracket spacing can be adjusted. Unconstrained compensator can be applied pipes overhead, trench laying, can also be applied have compensated Buried, without any constraint compensation should be located at manholes or darkroom. compensator straight pipe pressure balanced bellows (ZYP, Bo Yan Pipe ( certified merchants) are provided by Yanshan County Bo Yan Pipe Co., Ltd., Yanshan Bo Yan Pipe Co., Ltd.
