Is the PE pipe specification the outer diameter?

When purchasing and using PE pipes, many users will have questions about their specifications. One of the common questions is: Is the PE pipe specification an outer diameter? Today, we will discuss this issue in detail, and combine the PE pipe products of AD Pipe to clearly interpret the specifications of PE pipes for everyone.

First of all, it is necessary to make it clear that the specifications of PE pipes are usually based on their outer diameter as the main identification parameter. The outer diameter mentioned here is precisely the nominal outer diameter, expressed by the symbol "de", and the unit is millimeters (mm). For example, we often say that the PE pipes such as de20, de32, de50, de110, etc., the numbers in them represent the nominal outer diameter of the PE pipe. This way of using the outer diameter as the specification reference is the standard commonly used in the PE pipe industry. This is mainly because the PE pipe is mostly connected by hot melt or electrofusion, and the consistency of the outer diameter is crucial to ensure the quality of the connection.

AD Pipe As a professional pipe manufacturer, the PE pipes produced strictly follow this industry specification. On the product identification of AD PE pipes, in addition to clearly marking the nominal outer diameter (de), important parameters such as the wall thickness and pressure grade (such as SDR series or PN value) of the pipe are usually included, so that users can make accurate selection according to specific engineering needs. For example, a fully labeled AD PE pipe may be displayed as "PE100 de110 SDR17 PN1.6MPa", where de110 indicates the nominal outer diameter of the pipe is 110mm, SDR17 reflects the ratio of outer diameter to wall thickness of the pipe, and PN1.6MPa represents its nominal pressure.

Of course, it is not enough to just know the outer diameter. The wall thickness of a PE pipe is also a key factor in determining its pressure bearing capacity and range of use. Under the same outer diameter, different wall thicknesses of PE pipes will correspond to different pressure levels. AD Pipeline will provide a variety of PE pipe products with wall thickness and pressure levels according to different application scenarios, such as municipal water supply, rural drinking water, sewage drainage, gas transportation, etc., to ensure that each product can meet the corresponding engineering safety and performance requirements.

In summary, the specifications of PE pipes are indeed mainly expressed by their outer diameter (nominal outer diameter), which is the unified standard of the industry, which facilitates the communication and operation of design, construction and purchase links. AD Pipe always adheres to high standards and strict requirements, and strives for clarity and accuracy in the production and identification of PE pipes to provide reliable products and professional services for the majority of users.
