What is PVC drainage pipe
Pvc, known as the main raw material for polyvinyl chloride, polyvinyl chloride, adding other ingredients, improve its heat resistance, toughness, ductility. The top surface of the paint, the main ingredient in the middle is polyvinyl chloride, the back is back coating adhesive. It is the world's favorite, it is very popular and is a widely used synthetic material. Its global use of the highest of the two types of synthetic materials. According to statistics, in 1995 alone, polyvinyl chloride produced five million tons in Europe, and its consumption was 5.3 million tons. In Germany, the average production and consumption of PVC is 1.4 million tons. PVC is a 4% growth rate in worldwide production and application, so pvc drainage pipes are also very popular, and pvc drainage pipe specifications are even more extensive.
The essence of pvc is a kind of vacuum film, which is used for the packaging of various types of panel surfaces. It is also called decorative film, film, used in building materials, packaging, pharmaceutical and other industries. The building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and other small applications. Hard pvc drainage pipe has a nominal diameter of 50 cm, but soft pvc drain pipe is generally rigid 50 mm, pvc drainage pipe specification: GB/t13020-1991, soft pvc drainage pipe specification: GB/t13527.1-1992, hard pvc Drain pipe nominal diameter (unit: mm) 2.5,3,4,5,6,... 355,400,450,500,560,630,710,800,900,1000, etc. product name.

In recent years, pvc production in Southeast Asia is particularly important, which should be attributed to the needs of infrastructure in Southeast Asian countries. In the production of three-dimensional surface film material, pvc is the most suitable material. pvc can be divided into soft and hard pvc. Hard pvc about 2/3 of the market, soft pvc accounted for 1/3. Soft pvc is usually used for floors, ceilings, and leather surfaces, but due to the soft pvc containing softeners that are brittle and difficult to preserve, the range of use is limited. Hard pvc does not contain softeners, so it is flexible, easy to mold, not brittle, non-toxic, pollution-free, long storage time, it has great application value. Therefore, it is very important to clarify the specifications of the PVC drainage pipes and master the correct methods of use.

Pvc drainage pipe installation specification
First, pvc drainage pipe general structure requirements
(1) The design of the pipe bend determines whether the structure of the push-butt pier and the pier is to be set at the tee and elbow. If the pier of the pipeline is to be set, the back of the pipe should be close to the thick soil. Do not install it. In loose soil, if there is no thick soil on the back of the pier, measures should be taken to ensure the stability of the pier. Between the support pier and the pipeline should be set rubber cushion layer, its role is to protect the pipeline to prevent the destruction of the pipeline.
(2) The radius of curvature of the pipe bend should be within 300 times the radius of the pvc pipe.
(3)Prepared holes or mounting sleeves shall be provided through the wall of the pipeline. Liners and casing shall be filled with linseeds for filling. Within the scope of the casing, the pipeline shall not have an interface.
(4) In the wells set on the pipeline, the bottom of the well should be treated with waterproofing, and the jointing of the wellbore wall should be wiped. Sealing measures should be taken at the joint between the wellbore wall and the pipeline. This is to prevent the infiltration of groundwater.
(5) Pipes may adopt rubber ring interface or adopt RR connection, bonding interface or TS connection, flange connection, etc. The pipe with outer diameter of 63-315mm can be used for rubber ring interface or RR connection; the outside diameter is less than 160mm. Pipes can be used for bonding interfaces or TS connections; flanged connections are generally used for connection of hard PVC pipes to cast iron pipes or other pipes.
Second, pvc drainage pipe installation specifications
(1) The general laying process of the pipeline is divided into five steps. The first step is to put the pipe into the trench, the second step is to interface, the third step is partial backfill, the fourth step is pressure test, and the last step is full backfill. When putting the pipe into the groove, it can only be done if the conditions are not allowed and the pipe diameter is not large. When the conditions are met, three pipes are connected on the groove, and then the groove is put into the groove smoothly.
(2) When laying water supply pipelines in trenches, if it is not specified in the design that other materials must be used, it should generally be laid on undisturbed original soil.
(3) After the pipeline is installed, the pads used for laying the pipeline should be dismantled in time.
