DN500 SN12.5 carat pipe, buried sewage pipe

In the construction of municipal sewage pipe network, DN500 caliber carat pipe with SN12.5 ring stiffness is becoming a common configuration for deep buried sewage scenes. Carat pipe is a high-density polyethylene winding structure wall pipe, and its unique I-shaped winding rib design gives the pipe excellent resistance to external pressure. The ring stiffness of SN12.5 means that the pipeline can withstand a radial pressure of 12.5 kN per square meter, which is enough to deal with most motor vehicle lanes and deep soil discharge conditions, effectively preventing the deformation and collapse of the pipe wall.

The inner diameter of DN500 takes into account the large flow transportation and construction convenience. The inner wall is smooth, the Manning coefficient is low, and it is not easy to silt and scale, ensuring smooth sewage discharge. The material itself is resistant to acid and alkali, electrochemical corrosion, and has natural resistance to corrosive media in domestic sewage and general industrial wastewater. No additional anti-corrosion coating is required. The pipeline adopts socket-type electrofusion connection or throttling sealing connection. The interface strength is the same as that of the pipe body, forming a fully enclosed anti-seepage system to prevent sewage leakage and groundwater infiltration, which meets environmental protection requirements.

In the construction process, the pipe is lighter in weight than the traditional reinforced concrete pipe, and the lower pipe is flexible in hoisting, which can greatly shorten the trench exposure time and reduce the construction risk. Its flexible structure can also adapt to a certain degree of soil settlement and keep the pipe network intact for a long time. The selection of DN500 SN12.5 carat pipe is a practical choice from the perspective of engineering durability, sealing reliability and comprehensive cost, providing a stable conveying vein for the buried sewage system.
