Diet, also known as the expansion joint compensator or expansion joints. Constituting the body of work by the bellows (an elastic element) and the end of the tube, brackets, flanges, pipe and other accessories. Expansion joint is a flexible structure to compensate for additional stress due to the large expansion joints quality mechanical vibrations caused by the temperature difference between the first, and set in the container housing or piping. Axis with its body of work stretching deformation of the bellows effective professional wholesale large expansion joints to absorb pipelines, conduits, containers, etc. produced by the thermal expansion and contraction and other reasons dimensional changes large expansion joints, or compensate for pipelines, conduits, containers, etc. to, lateral and angular displacement. Can also be used for noise damping, on heating, in order to prevent heating pipe heating, the temperature stress due to thermal elongation or deformation or damage caused by the pipeline, we need to set compensation in the pipeline, with thermal compensation pipe elongation, thereby reducing stress and the role of the wall of the force on the valve member or scaffold structure. Metal expansion joint has been widely used in various industries of the national economy of industrial equipment and piping, typical operating conditions for pressure from vacuum to 6.4MPa, temperature from -196 ℃ to 900 ℃. It must be recognized bellows expansion joints belong highly technical products to ensure general piping elements of different large-scale expansion joints Shandong supplier, it is necessary to withstand the pipeline pressure (internal pressure, external pressure) when there is sufficient strength, while having sufficient flexible, to absorb thermal displacement and mechanical displacement expected to occur during use, so the wall thickness of the bellows is relatively thin material, typically 0.2-4.0mm. Work stress levels usually exceed qufu limit of the material, and therefore should pay attention especially large specialized wholesale expansion joint in all aspects of the product design, manufacture, inspection, warehousing, transportation, and testing in accordance with, Hopen hose ( online consultation), a large expansion joint is provided by Ning County Hopen stainless steel metal hose Limited. Ning County Hopen stainless steel metal hose Limited (www.haopengguanye.com) (www.haopengguanye.com) is Dezhou, hoses leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs.
