The role of steel flexible waterproof casing and anti-corrosion requirements.

Suitable production standards and materials should be selected according to the natural environment of different applications. For the natural environment with high moisture-proof regulations, steel flexible waterproof casing should be selected.
When the natural environment is a strong corrosive area, carbon steel should be selected as the raw material. The processing of steel flexible waterproof casing is mainly in the form of spring clamps and shell clamps, which are cantilevered when used. 
During the processing of steel flexible waterproof casing, sometimes the steel flexible waterproof casing will slowly protrude from the pipe or even fall off completely, resulting in the scrapping of the part. This is usually caused by insufficient pressure on the sealant ring between the steel flexible waterproof casing and the outer diameter of the steel flexible waterproof casing.
 
Flexible waterproof casing anti-corrosion requirements
Why flexible waterproof casing diagram to do internal and external anti-corrosion. After the flexible waterproof casing legend is made into shape, generally have to do anticorrosive rust removal spraying treatment on the inner or outer wall, on the other hand, for aesthetic purposes, in order to prevent the service life of the flexible waterproof casing legend from rust and corrosion.
After the production of flexible waterproofing casing legend, should be the first to its surface tube rust removal treatment, you can manually remove rust, can also spray rust removal, if there are no special requirements, then the rustproof primer and top coat in the flexible waterproofing casing legend and the media or atmospheric contact surface spraying, if the metal surface in contact with drinking water contact should be painted non-toxic epoxy primer and top coat.
02S404 flexible waterproof casing design requirements, external corrosion according to the site design requirements, internal corrosion according to the media use requirements, according to the rigid flexible waterproof casing drawings and flexible waterproof casing drawings of anti-corrosion treatment.
Steel flexible waterproof casing is used in the wall of the moisture-proof pipe, as steel flexible waterproof casing is classified as buried, but after installation can not be moved and removed and replaced, and therefore strictly in accordance with the installation method to carry out engineering construction.
