As an important part of urban infrastructure building, deep-sea sewage projects place extremely high requirements on the performance of pipeline materials - not only to withstand deep-sea high-pressure environments, but also to resist multiple challenges such as seawater corrosion and geological friction. Among many pipeline materials, HDPE carat pipe has become the "best choice" in the field of deep-sea sewage with its unique material advantages and structural design, providing a solid guarantee for the safety and long-term stable operation of the project.

From the perspective of the material itself, HDPE carat pipe is made of high-density polyethylene as the main raw material. This material has excellent chemical stability, which can effectively resist the erosion of acid and alkali substances in seawater and sewage, and avoid leakage or rupture of pipelines due to corrosion. At the same time, the molecular structure of high-density polyethylene is tight, the mechanical strength is high, and it is not easy to deform in the deep-sea high-pressure environment. It can withstand large external pressure and ensure that the pipeline system remains intact in complex working conditions.

In terms of structural design, HDPE carat pipe adopts a unique winding molding process to form a hollow wall structure. This structure not only reduces the weight of the pipeline itself, but also facilitates transportation and installation. It also improves the ring stiffness of the pipeline through reasonable mechanical design. Ring stiffness is a key indicator to measure the ability of the pipeline to resist external pressure deformation. HDPE carat pipe can adjust the ring stiffness grade according to the engineering needs, easily cope with the soil pressure and water impact at the bottom of the deep sea, effectively avoid the collapse or deformation of the pipeline, and ensure the smooth flow of the sewage channel.

In addition, the construction performance of HDPE carat pipe is also very outstanding. Its light weight, good flexibility, in the deep sea complex terrain (such as rock, sediment layer), can reduce the difficulty and cost of construction by flexible laying method, shorten the project cycle. At the same time, the pipeline interface adopts electric fusion or hot melt connection technology, and the sealing performance is excellent, which further reduces the risk of leakage and ensures the safety and environmental protection of the sewage discharge process.

Long-term use practice shows that HDPE carat pipe shows excellent reliability and durability in deep sea sewage discharge engineering. Its service life can reach more than 50 years, which is much higher than traditional pipeline materials, and greatly reduces the later maintenance cost. Whether it is from the perspective of material corrosion resistance, structural strength, or construction convenience and long-term economy, HDPE carat pipe is an ideal choice for deep sea sewage discharge engineering, and contributes an important force to urban marine environmental governance and infrastructure building. The choice of HDPE carat pipe of AD Pipeline is to choose a safe, efficient and reliable deep sea sewage solution.
