Xiaogan municipal pipe network construction, how to choose all kinds of plastic pipes

The commonly used plastic pipes for municipal pipe network construction mainly include polyethylene, polyvinyl chloride, polypropylene and other categories. Such pipes generally have the common characteristics of good corrosion resistance, light weight, low fluid transportation resistance, and long service life. They are the mainstream materials for replacing traditional metal and cement pipes in the current municipal engineering field. They have been widely used in various municipal pipe network construction projects in Xiaogan. Plastic pipes of different materials have different properties, and they need to be scientifically selected according to the actual needs of the project in order to adapt to the long-term use requirements of municipal pipe networks.

There are four core selection points, all of which are executable selection criteria: The first is to match the functional attributes of the pipeline network. There are obvious differences in pipeline performance requirements for municipal pipeline networks with different functions: drinking water pipeline networks need to prioritize categories with hygienic performance that meet the national standards for drinking water transmission and distribution equipment and strong impermeability; sewage pipeline networks need to select categories with strong acid and alkali corrosion resistance and impact load resistance; power communication piping networks need to select categories with standard insulation performance and strong extrusion resistance. All products need to be screened strictly according to the functional requirements of the pipeline network design to avoid functional mismatch affecting the use effect. The second is to adapt to the local construction and operation and maintenance environment in Xiaogan. Xiaogan belongs to the subtropical monsoon climate. It has high temperature and humidity in summer, and the extreme maximum temperature can reach more than 38 ° C. In winter, it is low temperature and cold, and the extreme minimum temperature can reach minus 5 ° C. At the same time, the groundwater level in some urban areas and counties is high, and there are differences in soil pH in some areas. When selecting, it is necessary to give priority to choosing pipeline products with temperature resistance range suitable for local climate and anti-settlement performance suitable for local geological conditions to reduce the impact of environmental factors on the service life of pipelines. The third is to meet the engineering design parameter standards. The core parameters such as nominal pressure, ring stiffness, and diameter specifications of the selected pipeline must strictly match the design requirements of the municipal pipeline network. Before purchasing, the supplier can be required to provide the corresponding batch of formal quality inspection reports. Check whether the parameters meet the relevant national standards for municipal engineering materials one by one. It is strictly forbidden to use products with substandard parameters and unknown sources. The fourth is to take into account the full-cycle cost of the project. Under the premise of meeting the design standards, the installation convenience, rated service life, and post-maintenance costs of different types of pipelines can be compared, and products with simple installation procedures and low maintenance frequency are preferred to reasonably control the construction and long-term operation and maintenance costs of municipal pipeline network projects.

The above selection logic is applicable to various municipal pipe network construction scenarios such as municipal water supply and drainage pipe network, rain and sewage diversion pipe network, power communication pipe network, and low temperature heat pipe network within the scope of Xiaogan, and is suitable for municipal engineering construction units, procurement departments, construction units, supervision units, and other relevant entities. It can be used as a reference for pipeline selection, procurement verification, and entry acceptance.

All plastic pipes used in the construction of Xiaogan municipal pipe network must comply with the relevant specifications for municipal engineering construction materials issued by the state, Hubei Province, and Xiaogan City. When entering the site, quality sampling inspections must be completed according to the project management specifications. Only after confirming that they are qualified can they be put into use. To ensure the construction quality of municipal pipe network projects from the material selection end and meet the public service needs of the city for long-term operation.
