Flexible waterproof casing is still not available, so you can only remove the blisters of the flexible waterproof casing, and reduce the loss of the remaining flexible waterproof casing. The flexible waterproof casing and the vessel shell are connected to by flange. Just weld the flange ring first, and then stop the flame correction, and the effect of the flexible waterproof casing will be lost. In this way, there will be no more waste of scrapped flexible waterproof casings, and these scrapped flexible waterproof casings have been used reasonably to reduce the waste of resources.
Usually during use, you will find water leakage when using casings or pipes, especially when encountering complex areas. In this case, you can use a casing as a casing protection tube and install a casing in the next step to solve the water leakage problem. When installing flexible waterproof casing, the following points should be paid attention to: First, whether there is water leakage and seepage in the casing, and secondly, detailed inspection of the casing through the wall is required. Then, the casing can be used as a waterproof casing protection tube and the waterproof casing is fixed with a rubber ring. If the casing is damaged, repair or re-welding should be repaired; if there is no damage, re-welding should be re-welded.
Product application requirements: The waterproof casing must be used in an environment with low temperature and high humidity, otherwise it will affect the service life of the waterproof casing. The exterior dimensions of the waterproof casing should meet the requirements of the drawings and must not be over-wide or over-thick. There must be no cracks or pores on the outer wall, and the casing should have higher strength steel. Before installing the casing pipe fittings, dust and oil stains on the surface of the casing should be removed first, and there should be no rust spots or debris. The inner and outer surfaces of the pipe fittings should be smooth and bright. The pipe must be connected to the pipe through the wall. The pipe through the wall must be suitable for waterproofing. The pipe through the wall must be waterproofing, and protective measures must be taken for its waterproofing. The outer diameter of the sleeve is DN200 or above. If a pipe passes through the casing through the wall, the pipe should be removed upwards outside the pipe, and then the sleeve passes through the pipe) and then the rubber ring is installed on the casing. The pipe is intact. After the rubber ring is installed, check whether there are bubbles and cracks on the outer wall of the rubber ring. If there are no bubbles, you can use hand to knock them away. If there are no cracks, you can remove them with tools and then rinse them with clean water and then use a hammer to loosen them.
