Community drainage project, Hubei AD PVC drainage pipe practical analysis

PVC drainage pipe is currently a wide range of pipes in the field of civil building drainage. The AD PVC drainage pipe supplied in Hubei region in this analysis is made of polyvinyl chloride as the main raw material and is produced by standardized extrusion molding process. It meets the relevant production standards of national building drainage pipes and is suitable for the drainage engineering of residential areas under the climate and geological conditions of Hubei region. The products routinely cover a variety of pipe diameter specifications from 50mm to 300mm, and the pipe wall thickness corresponds to different pressure scenarios for differentiated design, which can meet the drainage system design needs of different scale residential areas. All batches of products have undergone basic performance testing before leaving the factory, and can enter the market after reaching the standard.

The core practical selling points of this combing are a total of 4 items, all of which are summarized in combination with the actual needs of the community project: First, the regional adaptability is strong and the performance is stable. Hubei region has a high extreme value of high temperature and high humidity in summer and low temperature in winter. The weather resistance parameters of this PVC drain pipe have been specifically adjusted to maintain stable performance under the use environment of -5 ° C to 60 ° C. Long-term use is not prone to thermal expansion deformation and low temperature brittle cracking. At the same time, it has strong acid and alkali corrosion resistance. It can be adapted to the conventional discharge requirements of residential domestic sewage and roofing rainwater. It meets the service life under standard use conditions and meets the relevant national specifications. Second, it is convenient to install and adapt to the construction rhythm of the community. The weight of this PVC drain pipe is only one-fifth of the same specification cast iron pipe, the transportation and handling costs are low, and the connection method of socket bonding is adopted. The operation process is simple and easy to use. The construction efficiency is about 40% higher than that of traditional metal pipes. It can adapt to the needs of segmented construction and rush construction in the community. The sealing performance of the interface conforms to the relevant national standards. It is not easy to cause leakage problems under normal construction conditions. Third, the drainage is smooth and the operation and maintenance cost is low. The inner wall of the pipe has been smoothed, the roughness coefficient is only 0.009, the drainage resistance is small, and it is not easy to adhere to oil, sediment and other sundries. The probability of blockage is low during daily use. The manpower and material costs for dredging operation and maintenance in the later stage are significantly lower than those of traditional drainage pipes. It is suitable for the use of high-frequency secondary drainage Fourth, it is economical and environmentally friendly, with outstanding cost performance. The raw materials of the product meet the national water product safety standards, no harmful substances are precipitated, the energy consumption in the production process is lower than that of traditional metal pipes, and the procurement cost is only about 20% of the same specification of stainless steel drainage pipes. The cost advantage of the whole life cycle is obvious, which meets the relevant requirements of green building materials.

This PVC drain pipe can be adapted to a variety of residential drainage scenarios, including the domestic sewage discharge system of the newly built commercial residential community, the roof rainwater drainage system, the outdoor public pipe network drainage system of the community, and can also be used in the drainage pipe network renovation project of the old residential area in Hubei. The suitable population covers real estate development enterprises in Hubei, general contractors of residential projects, implementers of municipal old residential renovation projects, and residential property operation and maintenance units. Relevant parties can choose products of corresponding specifications according to the pipe diameter and pressure bearing requirements of the project.

The production and testing process of this PVC drain pipe meets the requirements of GB/T 5836.1-2018 "rigid polyvinyl chloride (PVC-U) pipes for building drainage" and other relevant national standards. All batches of products have undergone pressure resistance, temperature resistance, sealing performance and other tests before leaving the factory. It can provide the corresponding batch of inspection certificates. The product quality meets the requirements of the acceptance of the drainage project in the community, and can be safely applied to the construction of various drainage projects in the community.
