Flexible Water Hammer Elimination Tank can be used for protecting the pipeline system and reduce the effect of water hammer, inner surge tank has been used. The inner tank is a water storage container, preventing pipeline collapse or burst, improving the reliability and safety of the entire pipeline system greatly. The inner tank prepared by QuanCles® UHMWPE Fabric Reinforced TPU Membrane, reinforced with ultra-high molecular weight polyethylene fiber fabric, has performance advantages over traditional rubber material inner tank, such as light weight, high strength, impact resistance, and its flexible and foldable property also enable the inner liner to adapt to the shape and size of different pipeline systems during installation, reducing installation difficulty and time costs.
