Anonymous users2024-01-24The influence of the use environment on the life of PVC pipes The service life of PVC pipes can theoretically reach 50 years, but it is affected by many factors, according to the data: the ambient temperature of PVC pipes is generally 0 70, and the optimal ambient temperature is 5 60. Therefore, when PVC pipes are constructed, they should be buried in the ground as much as possible, or the piping should be installed indoors, and avoid heat sources, and if they really need to be installed outdoors, insulation materials (such as asbestos, glass fiber, foam, etc.) should be used to keep warm to prevent the pipe from freezing and cracking in winter.
According to the construction experience, the depth of the pipe (mainly refers to the main pipe above 63mm) should be buried at least above, at the same time, the pipe should not be in contact with hard substances such as stones when backfilling, and the sand needs to be covered with 10 30cm below and above the bottom of the PVC pipe and on both sides, so that it can avoid the frozen soil layer, and can not damage the pipe body when the pipe is subjected to external pressure. To solve the problem of thermal expansion and cold contraction, as long as part or all of the pipeline is used during construction, looper can be used.

Regulations on the sewer pipe of the toilet sewage pipe Generally, the middle wall of the sewage pipe mouth is 400-450mm on one side and 600-650mm on the other side (at the water tank or flush valve). Depending on the size of the bathroom, the size can be adjusted. The size of the sewer hole of the squatting pit from the wall depends on whether the water comes out of the front or the back. >>>More
The PVC pipe joint is also a place that is easy to seep water, and the re-melt pipe will be short, and it needs to be replaced again if it cannot be satisfied.
Hehe, it's definitely okay, it's just overkill, because the requirements and price of the water supply pipe itself are higher than the drainage pipe, and the price is much higher than the drainage pipe.
In most cases, you need to replace pipe fittings and local pipes, you still don't know very clearly, because whether the leakage location is convenient for maintenance and whether the pipe fittings can be replaced are influencing factors, to give you an idea, it is a last resort, in the case of indeed unable to achieve normal maintenance conditions, you can carefully deal with the surface of the leaking pipe, both sides of the interface should be treated, you need to throttle for a short time, do not have water at the interface, after the treatment is clean, use a piece of PVC pipe sheet of the same material as the pipe, Use a special glue to glue to the interface and fix it with something. PVC has a special adhesive glue, which is made of the same material as the pipe, as long as you clean the surface of the pipe and apply the glue evenly, you will be able to stop the water leakage. >>>More
Buy a small section of PVC pipe that is slightly thicker than the sewer pipe, just enough to cover the sewer pipe, follow the pipe opening so that it can be broken and set on the sewer pipe, wipe it evenly with PVC special glue in this pipe, and at the same time smear the PVC special glue on the leakage of the sewer pipe, put the pvc pipe in the sewer leakage, and tie it with a rope, and wait for the glue to dry and untie the rope.
