"Double-wall corrugated pipe DN225: How much is 1 meter? The relationship between weight and wall thickness"

In municipal drainage, road construction and other engineering fields, double-wall corrugated pipes are very popular because of their excellent performance and economical cost. Among them, DN225 is a relatively common specification, and many engineers and purchasers are very concerned about a practical question: how much does such a pipe weigh one meter? The answer to this question is not fixed, because it is closely related to a key parameter - wall thickness.

The structural characteristics of double-wall corrugated pipes determine that their weight is mainly determined by material density and physical size. At present, double-wall corrugated pipes on the market are mostly made of high-density polyethylene (HDPE) as raw materials, and their density is about 0.95g/cm ³. For pipes with DN225 (nominal outer diameter 225mm), the weight will vary significantly due to the different wall thicknesses required by their ring stiffness grades (e.g. SN4, SN8). The higher the ring stiffness, the thicker the wall thickness required, and the greater the corresponding weight per meter.

Generally, DN225 double-wall corrugated pipes that meet national standards (e.g. GB/T 19472.2-2017) have a weight range of about 5 kg to 8 kg per meter. For example, a pipe with ring stiffness SN4 has a relatively low minimum wall thickness requirement, and the weight per meter may be close to 5-6 kg; while in order to achieve higher SN8 ring stiffness, the manufacturer needs to increase the wall thickness to enhance the pressure resistance of the pipe, and its weight per meter will be correspondingly increased to 7-8 kg or even higher.

Therefore, there is no single standard answer to simply ask "How much is DN225 double-wall corrugated pipe 1 meter?". The most accurate approach is to consult the technical specification sheet of the specific product, which will clearly indicate the nominal weight of the product under the specific ring stiffness. During the engineering selection and procurement process, it is crucial to understand this proportional relationship between weight and wall thickness and ring stiffness. It not only helps you to accurately calculate logistics and installation costs, but also is key to ensuring that the piping system can meet the requirements of engineering mechanics. Next time you are choosing, be sure to specify the ring stiffness grade you need, so as to lock in the weight and wall thickness parameters that best meet the needs of the project.
