Rigid waterproofing applicable for pipe wear casing wall place from pipeline vibration and adjustable structure (built and things. For seismic fortification demand regions, such as the rigid waterproofing casing, should be in enter the pool wall or building exterior wall of pipeline on flexible connection nearby setting. Type A used in steel tube, B, C type used in ductile iron pipes and pipe.

Rigid waterproofing wing ring applies to pipe wall place from wear pipeline vibration and adjustable structure (built), applicable to build things pipe wall place in the limited space or piping installation before structure (built) things or pipeline built the renewal and transformation. For seismic fortification demand regions, such as the rigid waterproofing, should be in fin into the wall or building exterior wall of pipeline on flexible connection nearby setting.

Waterproof casing selection or processing, should satisfy pipeline design conditions and installation requirements, when necessary, the casing wall thickness of waterproof wear, axial thrust should be confirmed by the structural engineer.

Waterproof casing the installation position of should try to avoid the settlement joints, is adjustable seam or two more close structure (built and things. Special need, must be completed by structural engineer to choose.

When the material of the wall tube wear and diameter are beyond the scope of the atlas, etc, should pay attention to the structure, waterproof casing size and aperture used in packing etc make necessary changes and corrections.

Flexible waterproofing casing suitable for seismic requirements of the region, pipe wear wall place under vibration and pipe deformation, or have strict expansion of waterproof demand structure (built and content. Type A general for pool or wear interior wall, type B used to wear structure (built and things exterior walls. Ⅰ type sealing ring is generally applied to waterproof demand, Ⅱ type applies to a strict waterproof demand. Applicable temperature range:-20 ℃ ~ + 80 ℃. When wear wall tube and pump or pressurized pipe connection of pass in and out of equipment, appropriate in the joints flexible connection Settings.
