Municipal Pipe
Municipal pipe are usually buried underground (partly overhead) and need to be uniformly designed and laid out according to urban planning. They must have characteristics such as systematicity, concealment, and durability. Their construction quality directly affects the efficiency of urban operations and the quality of life of residents.

Municipal Pipe Supply
‌Municipal pipe refer to pipeline systems used to transport and discharge various fluids (such as water, sewage, rainwater, gas, etc.) in urban infrastructure construction. Pipeline networks constitute the lifeline of modern cities, supporting the normal operation of cities and the living needs of residents. The design and construction of municipal pipelines must follow strict standards and specifications to ensure their safety, reliability and durability.
Municipal Pipe Main Types
Municipal Pipe Material Selection
There are various materials for municipal pipelines, the most common ones are polyethylene (PE), polypropylene (PP), etc. Different types of pipeline materials are suitable for different application scenarios. For example, PE and PP pipes are becoming more and more popular in modern municipal engineering due to their excellent corrosion resistance and easy installation; while traditional materials such as cast iron and steel pipes are more often used in occasions with higher requirements for strength and durability.
Key points for municipal pipe construction and maintenance
Construction points
1.Trench excavation: Control the flatness of the base according to the characteristics of the pipe. Soft soil foundation requires laying a sand cushion layer (thickness ≥ 150mm)
2.Pipeline connection: PE pipes are connected by hot melt or electric fusion, and steel pipes are connected by welding or flange to ensure the quality of the interface.
3.Anti-corrosion treatment: The outer anti-corrosion layer of the steel pipe must meet the design standards (such as 3PE coating thickness ≥ 2.9mm).
Maintenance Management
1.Regular inspection: Use CCTV inspection, ultrasonic thickness measurement and other technologies to evaluate the internal condition of the pipeline.
2.Desilting and dredging: Stormwater pipes should be desilted at least once a year, and the desilting cycle of sewage pipes should be determined based on flow rate and water quality.
3.Emergency response: Establish a pipeline network geographic information system (GIS) to quickly locate fault points; reserve emergency supplies (such as plugging materials and pumping equipment).
