上海淞江减震器集团有限公司介绍：耐磨/耐负压DN125橡胶膨胀节产品信息，淞江集团为众多矿场配套耐磨橡胶接头，经过试验证明，该款耐磨橡胶接头使用起来非常耐磨，我厂承诺质保1年。
橡胶接头一般由内胶层、织物增强层（增强层有多层刮胶锦纶帘子布）、中胶层、外胶层、端部加固金属环或钢丝圈，经高温、高压硫化成型后，与金属法兰或平行接头松套组合而成的复合橡胶管。此产品利用了橡胶的高弹性、高气性、耐介质性、耐候性和耐辐射性等优点，可降低管道的振动及噪声，并可对因温度变化引起的热胀冷缩起补偿作用。
导流筒作用在冲刷力较强的管道膨胀节时，可以起到耐磨作用，使波纹管免受介质冲刷，起到延长膨胀节使用寿命的作用可以在膨胀节里起到导流作用，另外，导流筒的导向作用，可避免膨胀节在吸收管道变形时造成的波纹管失稳现象，从而使膨胀节达到其正常的使用寿命和作用。
Shanghai Songjiang shock absorber Group Co., Ltd. introduces: wear / negative pressure resistant rubber expansion joint information, Songjiang group provides wear-resistant rubber joint for many mines. The test proves that the wear-resistant rubber joint is very wear-resistant, and our factory promises to guarantee the quality for one year.
The rubber joint is a compound rubber pipe which is composed of inner rubber layer, fabric reinforcing layer (the reinforcing layer has multi-layer scraping nylon cord fabric), middle rubber layer, outer rubber layer, end reinforcing metal ring or steel ring. After being vulcanized at high temperature and high pressure, it is combined with metal flange or parallel joint loose sleeve. This product takes advantage of the advantages of rubber such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. It can reduce the vibration and noise of the pipeline and compensate the thermal expansion and cold contraction caused by temperature change.
When the guide tube acts on the expansion joint of the pipeline with strong scouring force, it can play a role of abrasion resistance, prevent the bellows from being scoured by medium, prolong the service life of the expansion joint, and play a guiding role in the expansion joint. In addition, the guiding role of the guide tube can avoid the instability of the bellows caused by the expansion joint absorbing the deformation of the pipeline, so as to make the expansion joint reach its normal Service life and function.
