We all know that we have to install drains when we decorate the kitchen, toilet and bathroom, and this is very important. So, what should we pay attention to in the drainage pipe construction scheme? What kinds of drainage pipe materials? Next, let’s follow Xiaobian to understand it!
First, what should we pay attention to in the drainage pipe construction scheme
1, First of all, we should follow the overall plan, the design of roads and buildings and the topographic elevation, sewage rain and other water to some factors, according to the pipeline is short, the buried depth is small, as far as possible the principle of self-flow discharge. Drainage pipes can be laid parallel to the road and around the building to minimize cross between each other and other pipes.
2, the pipeline must also be arranged on the outside of the road under the sidewalk or grass. In the design of drainage pipes, some horizontal distance and vertical clear distance between each other and other pipelines, it is necessary to carry out buried depth and construction maintenance according to the two pipelines so that they will not be affected by each other, and the size of the attached structures on the pipeline and local regulations also have certain factors.
3, when the drainage pipe turning place and handover place, the water flow Angle is generally not less than 90 degrees. And when the diameter of the pipe is less than 300, and the drop head is greater than 0.3 meters, the Angle is not restricted directly.
Second, what kinds of drainage pipe materials are
1, pp pipe it is a special drainage pipe, it is characterized by high hardness, heat resistance and no aging, and the density is also very small.
2, Pvc pipe is a kind of polymer material, which belongs to a special material in the drainage pipe.
3, it is known that plastic pipe is mainly made of and into resin, and then add some various auxiliary agents, materials and some reinforcement materials, etc., directly in the technical process of processing into molded solid pipe.
4, stainless steel pipe, this pipe is mainly used to transport fluids, such as oil, natural gas, etc., and stainless steel pipe it is also very strict in the production process.
5, PB pipe its freezing resistance and heat resistance is very good, can have low temperature impact resistance at -20℃, even in the cold pipe will not freeze crack, after thawing, the pipe can be directly restored, and its service life can reach more than 50 years.
