PE pipe is a pipe product that uses polyethylene as the main raw material for extrusion molding. The current mainstream application in the market is PE100 grade raw material production pipe. The nominal pressure covers the range of 0.6MPa to 1.6MPa, and the nominal outer diameter ranges from 20mm to 1200mm. It can be divided into solid-wall water supply pipes, structural wall drainage pipes, communication threading pipes, and other categories to meet different fluid transportation and protective wiring requirements. As the mainstream selection of pipes for the construction of municipal pipe networks and park pipe networks, the comprehensive cost-effectiveness of PE pipes has been verified by a large number of engineering cases. According to the climate and geological characteristics of Jingzhou and Huanggang, PE pipes can be adapted to the temperature range of 40 ° C in summer and -5 ° C in winter. They are resistant to medium pH soil corrosion and do not require additional anti-corrosion treatment for burial laying. They are suitable for the basic needs of long-term burial of the park pipe network.
The core selling points mainly include four points: The first is that the physical and chemical properties are suitable for the complex working conditions of the park. Under normal standard working conditions, the buried service life is not less than 50 years, and it has good corrosion resistance. It will not chemically react with acid and alkali components in the soil, transported domestic sewage, and conventional industrial wastewater, and there is no risk of rust and scaling. At the same time, the pipe has good impact resistance and flexibility, which can be adapted to the slight ground subsidence caused by short-term heavy rainfall in Jingzhou and Huanggang areas, and the short-term pressure fluctuation of the pipeline. The risk of pipeline fracture and leakage is much lower than that of traditional cement pipes and cast iron pipes. The second is that the construction and operation and maintenance costs are controllable. The weight of PE pipe is only 1/8 of the steel pipe of the same specification and 1/20 of the cement pipe. No large equipment is required for transportation and on-site hoisting, which can reduce the cost of on-site transshipment. The connection adopts hot-melt socket and hot-melt docking process. The strength at the interface is higher than that of the pipe body, and the sealing performance is excellent, which can avoid the problem of interface leakage after long-term use of the pipe network. Under the same construction conditions, the laying efficiency of PE pipe is about 30% higher than that of traditional cement pipe, which can shorten the construction period of the park pipe network. At the same time, the inner wall of the pipe is smooth, the roughness is only 0.009, the fluid transportation resistance is small, and it is not easy to adhere to scale and silt for long-term use. The cost of pipe network clearance and operation and maintenance is reduced by about 40% compared The raw materials for the production of PE pipes are non-toxic and will not seep harmful substances into the conveying medium. They meet the relevant standards for the transmission and distribution of drinking water, and can be adapted to the scene of direct drinking water and domestic water supply transportation in the park. There is no excess waste discharge in the production process of pipes, and the waste pipes can be completely recycled and reprocessed. They meet the environmental protection index requirements of the current green industrial park and low-carbon park construction in Jingzhou and Huanggang, and will not generate a construction waste disposal burden. The fourth is that the full specification covers and adapts to various types of procurement needs. The existing products cover PE pipes for all types of pipe networks such as water supply, drainage, and communication threading. The pressure level and pipe diameter specifications can match the parameter requirements of various pipe network construction in the park. The purchaser can complete the procurement of all types of pipes in one stop, without the need to connect with multiple suppliers, which can reduce the management cost of procurement communication and inspection.
In terms of applicable scenarios and people, the applicable scenarios first cover the construction of supporting pipe networks in various new industrial parks, high-tech zones, and economic development zones in Jingzhou and Huanggang, including park water supply systems, rain and sewage diversion drainage systems, power communication threading systems, fire water supply systems, etc.; secondly, it is suitable for pipe network renovation and rain and sewage diversion rectification projects in old industrial parks in the two places; at the same time, it can be used for supporting municipal road pipe networks in the park, pipe networks in employees' living areas, and internal pipe networks in industrial enterprises' self-built factories. The suitable population includes the procurement person in charge of the park development and construction unit in Jingzhou and Huanggang, the procurement personnel of the government procurement platform pipe network project, the material procurement post of the municipal engineering construction unit, the operation and maintenance service provider of the park pipe network, and the project procurement person in charge of the self-built factory area of the industrial enterprise.
The PE pipes introduced this time are produced in strict accordance with the current national standards such as GB/T 13663 "Polyethylene (PE) Pipeline System for Water Supply" and GB/T 19472 "Buried Polyethylene (PE) Structural Wall Pipeline System". Each batch of products has undergone multiple testing processes such as pressure resistance test, sealing test, and dimensional deviation test before leaving the factory. A full set of factory qualification test reports can be provided, and the purchaser can be entrusted with a third-party organization for inspection. It fully meets the qualification requirements for bidding for construction projects in Jingzhou and Huanggang parks, and can ensure project compliance and acceptance.
