脱硫烟气橡胶膨胀节，氟化橡胶膨胀节柔性接头
单球橡胶膨胀节又称单球橡胶接头，该产品是五金管道的一种柔性连接器。
单球橡胶膨胀节一般是由两端带橡胶凸缘的光滑波形补偿元件与金属法兰组成。金属法兰常采用活套式的，波形补偿元件的表面为橡胶，内层为数层强力纤维或钢带（丝）加强的夹层。在制作过程中，可用轮胎帘布作为加强层，加强纤维或钢带（丝）等加强夹层一直延伸到两端橡胶凸缘，凸缘内有硬钢丝骨架。波形内压波纹管内外表面必须光滑。
单球橡胶膨胀节有较大的位移补偿能力，可以进行轴向、横向和角向位移的补偿。有降低噪声、减小震动和一定的抗腐蚀能力。同时，通过不同橡胶品种的选配并用，改善风道橡胶补偿器的性能可使橡胶膨胀节适用于多种介质，故在工业生产中已得到广泛应用。但橡胶膨胀节不宜在高温条件下使用，许用范围较小，承载能力低，易受油脂浸胀和存在自然老化现象等。
上海淞江减震器集团是国内第一批制造管道减振设备的厂家，主要生产橡胶接头、可曲挠橡胶接头、阻尼弹簧减振器、橡胶隔震器、金属和非金属补偿器、管道伸缩器等管道减振给排水设备。技术创新是淞江集团多年来孜孜不倦的追求，也正是淞江产品深受市场一致好评的根本原因。

Desulfurization flue gas rubber expansion joints, fluorinated rubber expansion joints flexible joints
Single ball rubber expansion joint, also known as single ball rubber joint, the product is a flexible metal pipe connector.
The single ball rubber expansion joint is generally composed of a smooth wave shape compensating element with a rubber flange at both ends and a metal flange. Metal flanges are often used, the surface of the waveform compensation device for rubber, the inner layer of a number of strong fiber or steel strip (wire) to strengthen the sandwich. In the production process, the available tire cord fabric as reinforcing layer fiber or steel (wire) and strengthen the sandwich has been extended to both ends of the rubber flange, flange with hard steel wire frame. The inner and outer surface of corrugated inner pressure corrugated pipe must be smooth.
The single ball rubber expansion joint has large displacement compensation ability, and it can compensate the axial, transverse and angular displacement. To reduce noise, reduce vibration and a certain ability to resist corrosion. At the same time, through the selection and use of different rubber varieties, to improve the performance of the rubber expansion joint can be applied to a variety of media, so it has been widely used in industrial production. But the rubber expansion joints should not be used under high temperature conditions, with a smaller range, low bearing capacity, easy to be affected by oil immersion and natural aging phenomenon.
Shanghai Songjiang absorber group is the first batch of domestic manufacturing pipeline vibration equipment manufacturers, the main production can be flexible rubber joint, damping spring and damper, rubber isolator, metal and nonmetal compensator, pipeline expansion device reducing pipe water supply and drainage equipment. Technology innovation is Songjiang group for many years tireless pursuit, is Songjiang products by market comments from the root cause.
