Which PE 90 degree elbow manufacturer has the best product quality? I believe that for those who don't understand the pipeline industry, they can only let it go. The seller is what he says, and he lacks opinions. But if you read this text, I believe it will be difficult for those pe tube manufacturers to fool you. The quality of PE pipe is good or bad, we need to master the following points.

1. The inner and outer surfaces of PE pipes
Do not choose PE pipes with rough internal and external surfaces. Most of the pipes with rough surfaces are unqualified. It is likely that there are problems with the production process and raw materials. Such PE 90 degree elbows cannot meet the standard in terms of strength and are difficult to weld. , or if it breaks, the second is that the water flow resistance is large, which affects the water delivery efficiency.
2. View the inspection report of PE pipe
The technical indicators in the inspection report directly indicate the various indicators of PE pipes. We need to compare the standards issued by the country to check whether they are qualified. Among them, the more important indicators are: hydrostatic strength, longitudinal retraction rate, nominal size, average outer diameter, ring diameter, etc. Stress, test pressure, appearance, etc.
3. Check the elongation at break of the PE pipe
The elongation at break is one of the manifestations of the good flexibility of PE 90 degree elbow. The elongation at break of the pipe is measured to ensure the adaptability of the PE pipe to the uneven settlement of the foundation and meet the requirements of seismic performance.
4. Check the long-term hydrostatic strength of PE pipes
The long-term hydrostatic strength of PE 90 degree elbow and the ability to resist slow crack growth will all decrease, and the distribution of carbon black will be uneven. These points will affect the service life of the product, and there are potential safety hazards. The quality of pipes is the common concern of PE pipe manufacturers and users. Try to avoid buying inferior PE pipes and bring unnecessary losses to yourself. When purchasing, try to choose manufacturers with good brands, long production time and complete qualifications, so that after-sales service There are also guarantees.
