1.Product Introduction<\/b><\/strong><\/span><\/h3>\n

PE buried sewage pipes are thermoplastic circular pipes manufactured primarily from polyethylene (PE) resin via an extrusion molding process. They are specifically designed for non-pressurized buried drainage and sewage applications. Produced in accordance with the national standard GB\/T 45355-2025, this piping system is suitable for long-term use in buried drainage and sewage engineering projects where the operating temperature does not exceed 45\u00b0C.<\/p>\n

PE piping systems offer significant advantages in terms of material properties, structural design, and jointing technologies, making them a vital choice for modern drainage and sewage projects in municipal, construction, and industrial sectors. Their non-pressurized design makes them particularly well-suited for gravity-flow drainage and sewage systems, where they effectively bear external loads based on the scientific principle of soil-pipe interaction.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

3.Connection Methods<\/b><\/strong><\/span><\/h3>\n
    \n \t
  • <\/b>Socket and Spigot with Rubber Seal Ring:<\/b><\/strong>Utilizes a rubber seal ring, offering excellent sealing performance, convenient installation, and ensuring a reliable, leak-proof joint. This method provides good deformation resistance and is particularly suitable for quick installation in municipal engineering projects.<\/li>\n \t
  • <\/b>Butt Fusion:<\/b><\/strong>Involves heating the pipe ends to a molten state and then joining them under pressure, creating an integrated pipeline system with high connection strength and excellent sealing.<\/li>\n \t
  • <\/b>Electrofusion:<\/b><\/strong>Uses electrofusion fittings containing an internal heating wire to fuse the pipe and fitting into a single unit. This method is suitable for complex spaces and repair scenarios.<\/li>\n \t
  • <\/b>Flanged Connection:<\/b><\/strong>Suitable for connecting to equipment such as valves and pump stations, facilitating easy disassembly and maintenance.<\/li>\n<\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
