What are the common pitfalls to watch out for when purchasing PE pipes?
As the use and development of PE pipes continue to gain momentum in the pipe market, they are increasingly meeting the needs of more people. So, how can we choose high-quality PE pipes that are also affordable in today’s market? Meanwhile, as public awareness and understanding of PE pipes grow, many people have become better equipped to make informed choices. However, there are still some issues that require attention. Let’s take a brief look at the following common misconceptions!

Misconception 1: Some people think that... PE pipe The thicker the wall, the better.
Correct explanation: The nominal pressure refers to the working pressure at which a pipe can transport water at a secondary temperature (20℃). Common nominal pressures for PE pipes typically include 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa, and 1.6 MPa. However, the specific nominal pressure to be selected should be determined based on the requirements of the construction project. The higher the nominal pressure, the thicker the pipe wall will be, and consequently, the higher the pipe’s price will be. If one excessively pursues a high nominal pressure by increasing the wall thickness beyond what is necessary, the cost of the pipe will inevitably rise, leading to unnecessary waste of resources and costs. In fact, choosing an appropriately thick wall is always the best approach.

Misconception No. 2: Recycled materials PE pipe It's no different from PE pipe.
Correct interpretation: In the pipe market, there are often rumors circulating about methods for assessing the quality of PE pipes based on their appearance. While some of these methods can indeed be somewhat helpful, when purchasing PE pipes, it’s crucial to consult with a supplier and determine whether the material is recycled or virgin. This is because recycled materials—also known as regranulated plastics—have certain properties that differ from those of virgin materials. Of course, in applications where the requirements are not particularly stringent, recycled materials can still be used. However, if strict quality standards are involved, recycled materials may not be suitable to a significant extent. Typically, excessive use of recycled composite materials can lead to issues such as uneven pipe coloration, surface irregularities, bubbles, and an insufficiently smooth pipe wall. Therefore, when selecting pipes, it’s best to avoid those made from such recycled materials.

Misconception 3: National standard = Brand
Correct interpretation: “National standard” refers to: the production of PE pipe materials It must comply with the GB/T 13663.2-2018 standard for PE pipe production, which explicitly specifies the required technical indicators for manufacturing PE pipes. All pipes that meet the national standards will have these specifications. We can use this standard as a basis to determine whether a pipe conforms to the national standards—rather than falling into the common misconception that “brand equals national standard.” Therefore, in the PE pipe market, only “national standards” represent the ultimate brand.
