Which expansion joint manufacturer Hebei good / high quality expansion joints offer

Cangzhou Vietnam Pipeline Equipment Sales Co., sales of various types of metal and nonmetal compensation expansion joints expansion joints and other compensation - the overview compensator habits also called expansion joints, or expansion joints. Constituting the main body of the work by the bellows (an elastic element) and the end of the tube, brackets, flanges, conduits and the like accessories. Is a form of compensation components. Main body of the bellows with its work effectively stretching deformation to absorb axial pipe, conduit, container, etc. Dimensional changes caused by thermal expansion and contraction and other reasons arising from, or compensation lines, conduits, containers, etc., lateral and angular displacement. Can also be used for noise damping. Widely used in modern industry. On heating, the heating pipes in order to prevent warming, temperature stress due to thermal elongation or deformation or damage caused by the pipeline, you need to set compensation on the pipeline in order to compensate for the heat pipe elongation, thereby reducing stress and wall acts on the valve member or scaffold structure forces. Compensator - compensator compensator selection technique uses a rectangular cross section, rounded waveform, the pipeline expansion joint to withstand a single two-dimensional direction displacement. Toggle duct composed by the two expansion joint can withstand three-dimensional direction of displacement. Rounded rectangular metal bellows expansion joints have full-height, half-height, according to the flue size, stress and strain can require users to use multi-wave excerpt. 1, the user according to the displacement of piping hot selected after proper compensation, at least have to provide the flow of media within the tube, the design pressure of the smoke duct, the maximum temperature of the run-time, the smoke duct cross-sectional dimensions (length wide, the selected waveform) (full-height 216mm, half-height 108mm) and wave number (single corrugated single wave number no more than 6 waves) in order to compensate for the structural design and manufacturing. 2, the maximum amount allowed for each wave of expansion: Full-△ α = ± 24mm Half-△ α = ± 12mm. 3, block gray board: less dust on duct pipe can not use, for dusty flue gear gray board should adopt. 4, in order to reduce the number of sections wave bellows should be considered cold drawing 50 percent. 5, compensation applies to cross-sectional area less than 4.6 square meters and smoke duct dimensions less than 1.5m but there is one side more than 0.6mm occasions. Standard full-height bellows for all the smoke duct. Compensation - compensation Selection
