DISMANTLING JOINT COUPLING

The range of flanged dismantling joints has been prouced to give additional adjustment length and to help future pipe work modifications.

Ductile iron metal expansion joint is applicable for pipe through the wall of the vibration or structure requirement is tight waterproof, general manufacturing enterprise produce the waterproof casing according to the construction science research institute of design S312, 02 S404 standard atlases.

In case the wall where the flexible metal waterproofing cannula needs to pass through is not concrete, it should be switched to concrete walls, and the casing must be a set in the wall; Flexible waterproofing cannula is widely used in construction, chemical, steel, water, sewage treatment etc.

Generally, casing should be used when doing the pool, it is the channel pipeline leads to the pool. But ordinary casing is difficult to seal, thus there will be leakage between casing and pipeline, between the casing and the wall is easy to leak.
