Universal hinged bellows should be applied to various complex pipe systems to compensate for the angular displacement of various spatial pipe systems, such as L-type pipelines, Z-type pipelines, U-type pipelines and so on.
　　Its performance is characterised by the main angular deflection to compensate the synthetic displacement of multi-plane bending pipe sections. As the balancing ring, pin and hinge plate can withstand pressure thrust and other additional external forces, the expansion joint itself absorbs the internal pressure thrust and does not generate external forces on the pipeline, so the setup of pipeline support can be simplified.  The products are widely used in power plants, chemical plants, iron and steel plants. 2014 August Phoenix Zhangjiagou chemical plant purchased DN1200 expansion joints from our company.The qualified supplier of Yingkou North Sugar Industry Co., Ltd. has annual sales of more than 800,000 yuan.
