In municipal engineering, community construction, farmland irrigation and other scenarios, the choice of underground drainage pipe directly affects the stability and service life of the drainage system. HDPE carat pipe, as a new type of buried drainage pipe, has become the first choice for many projects by virtue of its unique performance advantages. Let's take a look at several major benefits of using HDPE carat pipe for underground drainage pipe.

First of all, it is light in weight, and it is more labor-saving to transport and install. HDPE carat pipe is made of high-density polyethylene, with a density of only about 0.94g/cm 3, and its weight is about 1/8 of that of traditional concrete pipe. This means that it can be easily transported manually without the need for large lifting equipment during transportation. During the installation process, the single section pipe is light in weight, reducing the dependence on excavators, cranes and other machinery, reducing the construction difficulty and equipment costs, and shortening the construction period.

is followed by high ring stiffness and strong compressive performance. HDPE carat pipe forms a reinforced structure similar to "honeycomb" through special structural wall design. Its ring stiffness can reach 8kN/m2, 12.5kN/m2 and other grades. It can effectively resist the extrusion caused by underground soil pressure, vehicle load and ground subsidence, avoid pipeline deformation or rupture, ensure the long-term stable operation of the drainage system, and reduce the problem of water leakage caused by pipeline damage.

is corrosion resistance and adapts to complex environments. Traditional concrete pipes or ordinary PVC pipes are susceptible to the erosion of acid and alkali substances in the soil, microorganisms and industrial wastewater after long-term burial, resulting in cracks, leakage, etc. The HDPE carat pipe has excellent chemical stability, acid and alkali resistance, salt spray resistance, and microbial corrosion resistance. It does not need additional anti-corrosion treatment after being buried in the ground. It is especially suitable for chemical industry areas, coastal high wetland areas, farmland and other environments that require high corrosion resistance of pipelines. It greatly extends the service life of pipelines.

At the same time, the construction is convenient and the interface treatment is simple. The interface of HDPE carat pipe adopts the rubber ring sealing connection method. During construction, only the pipeline interface needs to be aligned and the rubber ring can be compacted with special tools. There is no need for complex processes such as welding and pouring. This interface method not only has fast installation speed, single-stage construction efficiency is increased by more than 30% compared with traditional pipelines, but also ensures the tightness of the interface, reduces the risk of leakage, and also reduces the operation difficulty of construction personnel.

The last is long life and low maintenance cost. HDPE carat pipe has excellent material anti-aging performance. In buried environment, its molecular structure is stable and can maintain a service life of more than 50 years. In contrast, traditional pipes may need to be replaced in 10-20 years, while the long-term use of HDPE carat pipe can reduce the frequency of pipe replacement, reduce the later maintenance cost, and be more economical in the long run.

To sum up, HDPE carat pipe shows significant advantages in weight, strength, corrosion resistance, construction and life. It is an ideal choice for underground drainage pipes, which can provide strong protection for the stable operation and long-term use of drainage systems.
