Everybody knowspvc reinforced pipeThe main ingredient used inside it is actually polyvinyl chloride, but in addition to this, many other ingredients are added to increase its characteristics, and even a coating is added to the upper layer, and the lower layer has a back coating. Adhesive. In winter, the temperature in various places will gradually decrease, especially if it is in the northern region, the temperature will reach below 0 degrees, but the brittleness of pvc reinforced pipe will obviously increase when the temperature is relatively low, and it is very easy to crack. So in winter, how can we correctly use pvc reinforced pipe to avoid it from cracking?
After the purchase of PVC reinforced pipe, in the way of transportation must be standardized management, can not appear the phenomenon of violence, for example, directly fall on the ground, or even on the ground rolling drag, this will be on the PVC reinforced pipe appearance caused some damage. Therefore, in the process of installation and unloading, it is necessary to transport it with care, and to properly store it after arriving at the construction site to avoid direct contact with some sharp objects. It is important that the construction personnel cannot directly step on the surface of the PVC reinforced pipe, otherwise the inner wall of the pipe will be cracked or even burst.
In the process of construction, the depth of frozen soil in the northern region must be taken into account when digging the pipe trench, because the PVC reinforced pipe must be deeply buried under the soil layer, which is generally below 1.5 meters and above 1.2 meters. The width is to take into account the PVC reinforcement, the outer diameter of the tube is generally more than its outer diameter, the diameter of about 300mm is better.
At the same time, in the process of digging through, the stones and bricks inside must be taken out. If there are hard objects, some softer sand must be added. During the installation process, the PVC reinforced pipe is allowed to bend at an angle of only two degrees, and cannot be bent strongly, otherwise it will be damaged. Strict inspection must be carried out before the pipe is put down to avoid damage. If it is damaged, it should be replaced in time, and it should not be thrown into the ditch at will before construction.
If you want to use glue to connect the pipes together, firstpvc reinforced pipeThe inner wall of the socket and the insertion part of the outer wall of the socket are wiped clean with dry cloth, and the two ends are coated with a proper amount of adhesive to bring them together when they volatilize.
