1. Municipal Water Supply and Drainage: Producing urban municipal water supply pipes, such as HDPE and PPR pipes, to transport water from water sources to various areas of the city, and drainage pipes made of PVC and HDPE, for discharging urban sewage and rainwater.

2. Building Water Supply and Drainage: Producing water supply and drainage pipes for buildings, such as PVC drainage pipes, which are lightweight, durable, corrosion-resistant, and have high impact resistance. These can be used in building drainage, ventilation, and other systems. Also producing PPR and PE water supply pipes to provide a safe and reliable drinking water supply within buildings.

3. Agricultural Irrigation: Primarily used to manufacture plastic pipes for agricultural irrigation systems, such as drip irrigation pipes, sprinkler irrigation pipes, and irrigation water delivery pipes made of PE and PVC. These pipes are corrosion-resistant and weather-resistant, adaptable to various complex agricultural environments, and enable efficient use of water resources.
4. Wastewater Treatment: Production of pipes and related accessories for wastewater treatment plants, such as corrosion-resistant PVC and HDPE pipes, used in wastewater transportation and treatment processes, as well as plastic components in specialized wastewater treatment equipment, such as aerators and packing materials, helping to improve the efficiency and effectiveness of wastewater treatment.

5. Water Conservancy Projects: In water conservancy projects, plastic extruders can be used to produce HDPE large-diameter spiral wound pipes, geomembranes, and other products for seepage prevention and drainage projects in reservoirs, rivers, and dams, as well as small plastic components in water conservancy projects, such as drainage boards and filter screens.
