Ductile iron Gibault Pipe Coupling

Ductile iron coupling for ductile iron pipe is designed only for ductile iron pipe complying with BS EN545 or ISO2531, it is cheaper than universal flange adaptor & coupling. It provides a quick, leak free and reliable method of joining plain ended pipes for the conveyance of water and sewage

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. Waterproof cannula only solves the leak between the casing and wall, also can solve between casing and tube seal.

Custom casting ductile iron coupling

The coupling and flange adaptor will function as mechanical pipe joints for us in pipelines to facilitate the removal of valves and fittings without disturbing the pipelines and accommodate limited ground movement, expansion, contraction and angular misalignment of the pipeline.
