Food grade PE water supply pipe, urban and rural drinking water transportation pipe

The food-grade PE water supply pipe is a special water supply pipe produced by extrusion molding process with polyethylene as the core raw material that meets the national food contact material safety requirements. It is one of the mainstream pipe selection in the current urban and rural drinking water transportation scene. The whole process of the product from raw material screening to production and processing strictly follows the relevant specifications of drinking water transportation pipes. It has no odor and no toxic and harmful substances. It can be directly connected to the drinking water transportation system. It will not cause pollution to the water quality of transportation and is suitable for the needs of drinking water transportation projects of different scales. Compared with traditional galvanized steel pipes and cement water supply pipes, food-grade PE water supply pipes have obvious advantages in terms of hygiene, durability and construction convenience. At present, they have been widely used in various urban and rural drinking water projects in China.

core selling point

1. Hygienic performance meets drinking water delivery requirements

The raw materials of food-grade PE water supply pipes meet the safety standards for plastic materials used in food contact, and the production process does not add harmful additives to the human body. The pipe wall has high smoothness, and long-term use will not cause scaling or bacterial growth. There is no risk of secondary pollution to the transported drinking water, which can ensure the stability of water quality throughout the whole process of drinking water transportation.

2. Strong adaptability to working conditions and long service life

The food-grade PE water supply pipe has excellent chemical corrosion resistance, can withstand common acid and alkali soil erosion, drinking water residual chlorine corrosion, and will not appear the common rust leakage problem of metal pipes; the product has excellent impact resistance, and still has good toughness in the low temperature environment of minus 30 ° C, and is not prone to freeze cracking and deformation problems. Under conventional buried laying and normal operation and maintenance conditions, the service life can reach 50 years, which is suitable for geological and climatic conditions in different regions of urban and rural areas.

3. Construction and maintenance costs are controllable

The weight of the food-grade PE water supply pipe is only about 1/8 of that of the same specification steel pipe, and the transportation and handling difficulties are low, which can greatly reduce the transportation cost of the project in the early stage. The pipe adopts the connection method of hot-melt socket and hot-melt butt, and the interface sealing is good, which can effectively avoid the leakage problem after long-term use. The installation efficiency is much higher than that of traditional cement pipes and metal pipes. There is no need to do anti-rust and descaling treatment in the later operation and maintenance process. The operation and maintenance cost is only about 30% of that of traditional pipes. It is suitable for the cost control needs of large-scale pipe network laying in urban and rural areas.

4. Green environmental protection attributes meet standards

The production process of food-grade PE water supply pipes does not release harmful waste, and waste pipes can be recycled and reused without generating construction waste. It meets the relevant requirements of green building materials and is suitable for the development orientation of urban and rural green infrastructure.

Applicable scenarios and suitable populations

In terms of applicable scenarios, food-grade PE water supply pipes can cover various drinking water transportation scenarios such as the laying of urban and rural centralized water supply main networks, the transformation of village and town household support networks, rural drinking water safety improvement projects, the transformation of urban old community water supply pipe networks, and the construction of temporary drinking water transportation pipelines. It can also be adapted to some non-drinking water transportation scenarios with high water quality requirements. The compliance products currently on the market can provide full-specification selection from DN20 to DN1200, which can adapt to the parameter requirements of different flow rates and different laying scenarios.

In terms of adapting to the population, the product can meet the procurement and use needs of different entities such as municipal engineering procurement departments, urban and rural water supply operation units, pipe network construction units, residential development enterprises, and rural self-built housing owners. Small-diameter pipes can be adapted to household drinking water transportation, and large-diameter pipes can be adapted to regional water supply main network laying, with high flexibility in selection.

Compliance trust endorsement

The current compliance of food grade PE water supply pipes are strictly implemented "water supply polyethylene (PE) piping system, Part 2: Pipe" (GB/T 13663.2) related production standards, while meeting the "food contact plastic materials and products" (GB 4806.7) safety requirements, each batch of products need to pass the pressure test, health performance testing and other multi-channel inspection links before leaving the factory, can provide the corresponding batch of qualified test reports, fully meet the compliance acceptance requirements of all kinds of drinking water transportation projects, can be assured for all kinds of people's livelihood drinking water project construction.
