Rigid waterproof casing should pay attention to the problem

Rigid waterproofing casing should pay attention to the problems, rigid waterproofing casing specifications than the span of the pipe diameter of one level, welding rigid waterproofing casing specifications, welding seams full, no cracks, sand eyes, no welding waterproofing casing. Installation of rigid waterproof casing specifications. The direction should be accurate, rigid waterproofing casing specifications are not skewed. Rigid waterproofing casing specifications inside the mouth to round, clear the weld scars, burrs. Water supply and drainage pre-buried engineering construction, should be based on engineering drawings, compared to the upper and lower engineering drawings, make fire hydrant pipe pre-buried holes and kitchen, bathroom pre-buried holes. Kitchen, bathroom wire and pipe installation, to prevent damage to the wire and pipe during installation. When the drainage riser crosses with the construction line of the external wall, holes or holes shall be reserved.
Rigid waterproof casing length to be shorter than on the casing, and installation to fix the casing to the wall, so be sure to pay attention to the installation method and the casing in the environment whether there is water, so as not to affect the casing. The casing is also fixed in many ways, not detailed here. The installation method of rigid waterproof casing is the simplest and most convenient. When threading in the pipeline, it is usually only necessary to bury the line in the casing. In order to prevent the pipeline deformation caused by the casing to fall or damage during threading will need to be welded to the casing. It can be welded with heat or electric welding. Then use a wrench to compact the casing and then put the casing into the wall, so that the effect is very good. After threading the waterproof casing needs to be painted around and must be sealed, after which it should be wrapped in plastic and placed in the shade. The next day you can thread the wall to use. This is done. Rigid waterproof casing installation method is very simple and convenient. And it can also avoid damage during use.
When installing, we should pay attention to the casing around the level, do not leave a gap, and to ensure that there is space around the casing, so as to prevent the casing from deformation after the force of the wall from detachment, so that it can not be well fixed. The production process of waterproof casing is very important. When making the casing to ensure that the quality and appearance of the casing is not a problem before welding, and then soak it in water for a period of time until there is no problem, and then proceed to welding work. Before welding, we need to check the sealing of the rigid waterproof casing and the quality of the situation, if there are problems we have to deal with in a timely manner. If there is a problem must be dealt with, and then in the welding rod to repair until the use again. If there is a problem that needs to be checked again, then we can re-weld. The casing must be coated with anti-rust oil before the pipe is installed again. The casing also ensures that it is effective and can be used for a longer period of time.
