Polyethylene pipe dimensions

Polyethylene pipe dimensions mainly include outer diameter and wall thickness. The specific specifications and standards are as follows: ‌

1. ‌Outer diameter and wall thickness standards‌: The outer diameter and wall thickness of polyethylene pipes have certain limit deviation standards.

2. ‌Common specifications‌: Common specifications of polyethylene pipes include dn10, 25, 32, 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 225, 250, etc. The standard length is usually 4000mm or 6000mm.

3. Specifications of double-wall corrugated pipes: Polyethylene double-wall corrugated pipes are divided into S1 type (ring stiffness ≥ 4KN/㎡) and S2 type (ring stiffness ≥ 8KN/㎡), with specifications of Φ110, Φ160, Φ200, Φ225, Φ300, Φ400, Φ500, Φ600, Φ700, Φ800, etc.

4. Specifications of heat-resistant polyethylene: There is no fixed standard for the specifications of heat-resistant polyethylene (PE-X), but it is determined according to specific usage requirements and application scenarios, such as hot and cold water pipes, heating system pipes, solar energy pipeline systems, and industrial fluid delivery systems, etc., and the pipe diameter and wall thickness will be different.

Material grade: Polyethylene pipes are divided into five grades internationally: PE32, PE40, PE63, PE80, and PE100, of which PE80 and PE100 are mainly used for gas pipes and water pipes.

Application of polyethylene pipes of different sizes

Polyethylene pipes provide a variety of size options to meet different needs due to their excellent performance and wide application fields. Polyethylene pipes (PE pipes) have a wide range of specifications and size options according to their use, pressure level and specific application scenarios.

First, according to the use classification, polyethylene pipes can be divided into the following categories:

Water supply pipes: used for household and industrial water supply systems, with specifications from DN15 to DN600, and the length is generally 4 meters or 6 meters.

Sewage pipes: used for sewage treatment and discharge, with specifications from DN50 to DN1000, and the length is generally 4 meters or 6 meters.

Power pipes: used for the laying and protection of power cables, with specifications from DN15 to DN300, and the length is generally 4 meters or 6 meters.

Communication pipes: used for the laying and protection of communication lines, with specifications from DN15 to DN600, and the length is generally 4 meters or 6 meters1.

Secondly, according to the pressure level and specific application scenarios, the specifications and sizes of polyethylene pipes are as follows:

‌Small-diameter household water: The inner diameter ranges from 16mm to 63mm, which is suitable for household tap water pipes to meet daily water needs.

‌Medium-diameter industrial transportation: The inner diameter ranges from 75mm to 315mm, which is suitable for industrial transportation pipelines and can withstand higher pressures.

‌Large-diameter industrial and urban pipelines: The inner diameter ranges from 400mm to 1600mm, which is suitable for large-scale industrial and urban water supply and drainage systems.

Finally, the advantages and application scenarios of polyethylene pipes of different sizes in specific applications include:

‌Small-diameter pipes: Such as water supply pipes from DN15 to DN60mm, suitable for household and industrial water supply systems, requiring good pressure resistance and environmental protection performance.

‌Medium-diameter pipes: Such as sewage pipes and power pipes from DN75 to DN315mm, which require good corrosion resistance and wear resistance.

Large diameter pipes: such as industrial and urban pipes from DN400 to DN1600 mm, suitable for large-scale water supply and drainage systems, requiring higher strength and pressure resistance.

Advantages of polyethylene pipes

1. Polyethylene pipes have excellent corrosion resistance and can resist the erosion of various corrosive media such as acids, alkalis, and salts. This feature enables polyethylene pipes to maintain long-term stable operation when conveying media containing corrosive substances, reducing leakage and replacement frequency caused by corrosion, thereby reducing maintenance costs. In addition, polyethylene pipes have good chemical stability and can convey various corrosive media and organic matter. ‌

2. Polyethylene pipes are light in weight and easy to install. Compared with traditional steel pipes, polyethylene pipes have low density and light weight, which is easy to carry and install, reduces labor intensity, and improves construction efficiency. At the same time, polyethylene pipes have various and simple connection methods, such as hot melt connection, electric fusion connection, etc., which do not require complex welding processes, further simplifying the installation process. ‌

3. Polyethylene pipes also have high strength and excellent physical properties. Its material is uniform, the density distribution is particularly reasonable, it is not easy to have pipeline fluctuations and warping, it has high strength, and there will be no pipeline cracking, which ensures the safety and stability of the system. Especially in low temperature environments, polyethylene pipes can still maintain good flexibility and impact resistance, and are not prone to brittle cracking or breaking.‌
