Flexible Wall Penetration Sleeves are an option to create a hole penetration in a concrete wall. Flexible wall sleeves are widely used for pipeline passing the walls, ceilings or floors which suffering vibration or concrete structures such as tanks, manhole chambers, shafts, floor slabs and basements of strict watertight requirement.

Rigid Water proof Casing(A):

The Rigid water proof wall sleeve installation is suitable in the pipeline puts on the wall place, and can not withstand the pipeline vibration and the construction building which is expansion distorted. Regarding the area requiring earthquake fortification, should establish the flexible connection nearby in the pipeline entering the wall or on the building outer wall if the rigid waterproof casing is used. A is suitable for the steel pipe.

Rigid Water-proof Coupling(B):

Rigid water-proof applied to the building which will not withsatnd vibration and telescopic deformation in the pipe wall. In the area which required earthquake protection, if you use rigid waterproof coupling, you should set flexible connection on the pipeline of exterior wall or the sidewall of tank, Type B applies to ductile iron pipe.

Notes:

1. Please give clear indication of type,wall thickness and external diameter.

2. The big DN size can be adjusted in accordance with requirements of users.

3. The sizes of the data are select label ,so welcome the construction.
