Waterproof casing mainly S312 series and 02 s404 series waterproof casing, add my company in the engineering of waterproof casing can facilitate engineering pipeline, the convenient and quick, and prevent the building of adverse impact on metal pipeline, metal pipeline no micro cracks appear. Waterproof casing falls into two types: the rigid waterproof and flexible waterproof casing pipe, rigid waterproofing casing are applicable for pipe through the wall of general requirement general waterproof building, flexible waterproof casing is mainly suitable for pipe needs through a vibration of the pipe wall in the process of use, can effectively slow down the pipeline vibration to prevent wall loss and the influence of cracks. Waterproof casing because of its convenient use and so widely used in pipeline settlement area, equipped with waterproof casing to prevent wall body and ground for pressure pipeline, ensure smooth pipes.
In the construction site, the field environment is very complex is different to the requirement of waterproof casing; especially the thickness of the casing is also need to pay attention to. So at the time of the structures through the pipe, need to wear casing wall has long have short, today is mainly about the scope of flexible waterproof casing lengthened.
Long flexible waterproof casing is on the basis of the GB standard waterproof casing the overall performance down to the length of the longer, the length is determined according to the thickness of the wall, in determining the waterproof casing length of time just need to make sure that the wall thickness. In practice, to add wing ring in the middle of flexible waterproof casing, lengthened the wing ring is on the basis of others add, its purpose is to enhance the stretched flexible waterproof casing pressure resistance and protect pipeline.
Generally in install and use, with the national standard of flexible waterproof casing installation method, its action, the only difference is on the basis of original increased its length. Due to the growth of the length of flexible waterproof casing, lengthened the corresponding price will be increased.
