Double Flange Single Sphere(WRAS)
产品特性/Product Feature
■ 可以大大降低管道系统的震动和噪声，可根本上解决各类管路的接口位移，轴向伸缩及不同心度等问题。
■ 根据材料不同，可多个个品种，适应多种介质和环境。
■ 橡胶密封性好，重量轻，安装维修方便，使用寿命长，避免与锋利金属器械接触，以免刺破球体。
■ 如在空中使用可配弹性支架。
■ 如管路压力过高，应使用极限螺栓将两端法兰连一起。
■ 可应用于饮用水管道。
■ The ruber joint can greatly reduce pipeline system vibration and noise, can solve the problem of joint displacement, axial expansion, etc.
■ According to different materials, it can be made into many kinds, adapt to many mediums and different environment.
■ Good sealing rubber, light weight, easy installation, long service life, and avoid contacting with sharp metal device.
■ If use overhead, can match with elastic support.
■ If pipeline pressure is high, should use bolt connect the flange both ends.
■ It can be used for drinking water pipelines.
