How to see the grade of HDPE double-wall corrugated pipe

In municipal construction, drainage and sewage and many other engineering fields, HDPE double-wall corrugated pipes have been widely used due to their excellent performance. And choosing the right grade of pipe is essential to ensure the quality of the project and long-term stable operation. Many users will have questions when purchasing: What do you think of the grade of HDPE double-wall corrugated pipes? As a professional pipeline manufacturer, AD Pipe will explain it in detail for you here.

Generally speaking, the grade of HDPE double-wall corrugated pipes is mainly divided by its ring stiffness, which is a key indicator to measure the ability of pipes to withstand external pressure. We can generally see clear signs on the outer wall of the pipe, and the number followed by "SN" is an important parameter indicating the ring stiffness grade. For example, the common SN8, SN10, SN12.5, SN16, etc. The numbers here represent the ring stiffness level of the pipe, which is expressed in kilograms per square meter (kN/m ²). The larger the number, the higher the ring stiffness of the pipe, the greater the external pressure it can withstand.

HDPE double-wall corrugated pipe produced by AD Pipeline strictly follows relevant standards on the product identification, and clearly marks various important parameters including ring stiffness grade. When purchasing, users can quickly identify the grade by looking at the inkjet code information on the outer wall of the pipe. These inkjet codes not only include the SN grade, but also may include pipe specifications, production standards, production dates, and brand logos of AD Pipeline, ensuring the transparency and traceability of product information.

In addition to directly checking the SN logo, understanding the application scenarios corresponding to different grades can also help to make better judgments. Generally speaking, HDPE double-wall corrugated pipes with SN8 grade and above are more commonly used. SN8 grade pipes are suitable for general buried drainage and sewage projects, and are more suitable for areas with relatively small soil pressure and ground loads. When the environment in which the project is located requires higher bearing capacity of the pipe, such as large burial depth, complex soil conditions or may withstand heavier ground loads, SN10, SN12.5 or even SN16 grade products need to be selected. AD Pipeline will recommend suitable grades of HDPE double-wall corrugated pipes for customers according to the specific needs of different projects to ensure that the pipes perform best in practical applications.

In addition, through the technical parameter table of the product or consult the professional sales staff of AD Pipeline, you can also obtain accurate grade information. AD Pipeline always insists on providing support to customers with high-quality products and professional services, helping users to have a deep understanding of product characteristics, so as to make the most suitable choice.

In summary, it is not complicated to identify the grade of HDPE double-wall corrugated pipe, which is mainly determined by looking at the SN logo on the pipe. When purchasing, it is recommended that you choose a strong and reputable brand like AD Pipeline. Its products not only have clear and standardized grade labels, but also have more guaranteed product quality and performance. I hope that through the above introduction, you can have a clearer understanding of the grade identification of HDPE double-wall corrugated pipe, so as to choose the right pipe for your engineering construction.
