Elastic compensation element expansion joints of a freely scalable, with reliable, good performance, compact structure, etc., large-scale expansion joint bellows expansion joints quality first, with reliable, good performance, compact structure, etc. for large-scale expansion joints Shandong cargo business, has been widely used in chemical, metallurgy, nuclear energy and other sectors. I continue to strengthen the development of new products, to science and technology, adhere to strict scientific management, adhere to the quality of corporate life, adhere to good after a large expansion joint lowest price, to win the majority of users. The quality of survival, integrity and development, people-oriented, technology innovation! Welcome to the new and old customers to come to inquire, negotiate! 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 joints to compensate for the additional stress caused by the temperature difference caused by mechanical vibration, and a flexible structure is provided on the container housing or piping. 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. 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.
