Corrosion resistance and high strength, carat pipe is the first choice for municipal drainage

Carat tube core performance matches the needs of municipal drainage scenarios

The municipal drainage pipe network undertakes domestic sewage, industrial wastewater and surface runoff all year round. The pipes need to withstand acid and alkali corrosion, cope with geological settlement pressure, and avoid leakage and pollution of the surrounding soil. The carat pipe is made of high-density polyethylene as the core raw material and adopts the hot winding molding process. The pipe wall structure is stable, and the ring stiffness can be adjusted on demand. It can not only withstand acid and alkali medium corrosion of different concentrations, but also has a service life of more than 50 years. It can also withstand soil pressure and road load of different burial depths, effectively avoiding the pain points that traditional cement pipes are prone to cracking, leakage, and short service life. It is suitable for the use needs of various municipal drainage projects.

Selection Points of Carat Pipe in Municipal Drainage Engineering

When selecting the project, the corresponding ring stiffness grade should be matched according to the buried depth of the pipeline and the load above. If the buried depth exceeds 3 meters or the road section above is a motor vehicle lane, it is recommended to choose a product with a ring stiffness of ≥8kN/m2, and a product with a ring stiffness of 4kN/m2 can be selected for the green belt and non-motor vehicle lane areas with a shallow buried depth. At the same time, it is necessary to focus on the inspection of the interface sealing and raw material compliance of the product. Avoid the use of inferior products produced from recycled materials to prevent leakage and deformation in the later stage.

Key points of standardized construction of carat tubes

Before construction, it is necessary to clean up the sharp stones and debris in the trench, and do a good job of base leveling to avoid scratches on the pipe wall affecting the service life; before the interface connection, clean up the stains on the socket part to ensure that the sealing ring is placed in place, and after connection, do an air tightness test to confirm that there is no leakage; when backfilling, use a layered tamping method to avoid the displacement of the pipeline due to unilateral force. During construction in the rainy season, it is necessary to do a good job of trench drainage to prevent the pipeline from being dislocated due to buoyancy.

Compared with traditional drainage pipes, carat pipes have lower transportation and construction costs, less difficulty in later operation and maintenance, and obvious comprehensive cost-effective advantages. They have now become the mainstream choice for various types of new and reformed municipal drainage projects.
