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 Taiyuan compensator, unconstrained 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 the ability to self-oriented, complete elimination of 4D, 14D, L3 constraints Wuxi compensation, to overcome the installation error, small, safe and reliable, but also can eliminate the conventional axial compensator It is prone to bending and torsional buckling and other common diseases, and pipe insulation has brought great convenience. Spacing Unconstrained compensator to compensate for axial compensation pipeline, the compensation amount, with a strong self-steering and superior bending resistance Shanghai compensation, which can simplify the design of the pipe guide bracket, the guide bracket can be installed arbitrary regulation. Unconstrained compensator can be used in aerial, trench laying pipe, it can also be applied to have compensation Buried, without any constraint compensation should be located at manholes or darkroom. Special three-dimensional pulverized coal pipe bellows (MSW type) for more information: special three-dimensional pulverized coal pipe bellows (MSW type), also known as pipeline compensation, pipe expansion joints, bellows expansion joints. Pipeline compensation is designed for pulverized coal pipeline design of a special compensation, pipeline compensation bellows is 1Cr18Ni9Ti or SUS304 material manufacturing. Pipeline compensation multi-layer first hydroforming process, can compensate for axial, angular, lateral displacement synthesis and various orientations. Special three-dimensional pulverized coal pipe bellows (MSW type) with strong wear resistance, large amount of compensation, product performance, and long life, and other advantages. Therefore, this pulverized coal pipeline compensation praised by users. High speed friction and unreasonable product structure of coal is the main cause of premature failure pipeline compensation. Pipeline compensation draft tube with thick wear-resistant steel combined with different structural design, "Longsheng card" special three-dimensional pulverized coal pipe bellows more superior performance, as the bellows industry leader. Special three-dimensional pulverized coal pipe bellows (MSW) is used for coal, gas-solid flow of hot air. Pipeline compensation flow rate of 15∽30m / s, temperature 60 ℃, wind pressure ≤500mmH2O primary air, tertiary air, tertiary air duct in any direction displacement compensation Shanghai compensation, compensation, Bo Yan Pipe (view) from the salt Yamagata Bo Yan Pipe Co.
