How to choose PE pipe


Release time:

Mar 29,2022

PE pipe is polyethylene pipe, widely used. Because of its high strength, high temperature resistance, corrosion resistance, and non-toxicity, it overcomes the shortcomings of galvanized pipes and cast iron pipes such as easy corrosion, scaling, breeding bacteria, and short service life. In addition, the strength of the hot melt or electric fusion interface of PE pipes is higher than that of the pipe body, The joint will not break due to soil movement or live load, and has excellent corrosion resistance: except for a few strong oxidants, it can resist the erosion of various chemical media without electrochemical corrosion, PE pipes can be safely used for more than 50 years under rated temperature and pressure, with long service life, light weight, simple welding process, convenient construction, and low comprehensive engineering cost.

怎样挑选PE管

Excellent corrosion resistance: Except for a few strong oxidants, it can resist the erosion of a variety of chemical media, no electrochemical corrosion, PE pipes can be safely used for more than 50 years under rated temperature and pressure, long service life, light weight, and welding technology Simple, convenient construction, low comprehensive engineering cost.

In addition to thisPE pipeThere are many construction technologies. In addition to traditional excavation methods, new non-excavation technologies such as pipe jacking, directional drilling, lining, and pipe splitting can also be used for construction. This is the only option for some places that do not allow excavation, so the application field is wider.

With the increasing demand for PE pipes, various PE pipes have appeared on the market. It is undeniable that the market is mixed, and many PE pipes do not meet quality standards. This will not only affect the use of consumers, but also affect the quality of the project, laying hidden dangers for people's production and life in the future. Therefore, it is very important to learn to identify the quality of PE pipe. Below, Xiaobian introduce three methods to distinguish the pros and cons of PE pipe!

1. Look at the appearance

PE pipe: the inner and outer surfaces of the pipe are smooth and free of defects such as bubbles, dents and impurities.

Poor quality PE pipe: the inner and outer surfaces of the pipe are not smooth, bright, pitted and obviously depressed.

2. Milling strip

High-quality polyethylene pipe: shiny and smooth, not easy to break after repeated folding.

Inferior PE pipe: dark color, easy to break when folded.

3. Welding port

QualifiedPE pipeThe welded joint shall have smooth and symmetrical flanging along the entire circumference of the pipe, and the depth of the flanging shall not be lower than the pipe surface; the misalignment at any position on both sides of the weld near the outer circumference of the flanging shall not exceed 10% of the thickness of the pipe wall.
