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

In municipal drainage, underground pipe network construction and other projects, HDPE double-wall corrugated pipe is widely used. However, in the face of a wide variety of HDPE double-wall corrugated pipes on the market, how to accurately judge its grade has become the focus of engineering builders. HDPE double-wall corrugated pipe grade can be determined by looking at product identification, inspection reports, etc. Understanding these judgment methods will help to purchase high-quality pipes that meet engineering needs.

product identification is an important basis for quickly checking the grade of HDPE double-wall corrugated pipes. Generally speaking, HDPE double-wall corrugated pipes produced by regular manufacturers will clearly mark the relevant information of the product on the surface or outer packaging of the pipe, including the ring stiffness grade. The common ring stiffness grades of HDPE double-wall corrugated pipes are divided into SN4, SN8, etc. The "SN" here represents the ring stiffness, which is an important indicator to measure the pipe's ability to resist external pressure. The larger the number, the higher the ring stiffness, the stronger the pipe's ability to withstand external pressure. For example, the SN4 grade HDPE double-wall corrugated pipe has a ring stiffness of not less than 4kN/m2, which is suitable for some occasions with relatively low external pressure requirements, such as internal drainage pipes in residential areas; while the SN8 grade pipe ring stiffness is not less than 8kN/m2, which can withstand greater external pressure and is more suitable for use in busy traffic sections or urban drainage projects with large buried depths. When purchasing, construction personnel only need to carefully check the pipe label to initially understand whether its grade meets the engineering needs.

inspection report is the authoritative basis for determining the grade of HDPE double-wall corrugated pipe. Regular HDPE double-wall corrugated pipe manufacturers will conduct strict quality inspections of pipes before leaving the factory and issue corresponding inspection reports. The inspection report will record various performance indicators of the pipe in detail, including ring stiffness test results. By viewing the inspection report, engineering builders can obtain accurate and detailed pipe grade information to determine whether the product meets national standards and engineering design requirements. When checking the inspection report, pay attention to the validity and authenticity of the report, confirm whether the report is issued by a qualified testing agency, and whether the test date, product batch number and other information on the report are consistent with the purchased pipe.
