Modern people are paying more and more attention to whether the building materials used for decoration are environmentally friendly and healthy. In many cases, whether a product is environmentally friendly has become a deciding factor for consumers to purchase. In terms of pipelines, PE pipes have solved the sanitation and construction problems of traditional water pipes, greatly improved their practicality, and also have great advantages in terms of quality, price and environmental protection. They have gradually replaced traditional pipes and become more and more trusted by people. . In this issue, I will share with you the content about which PE pipe brand has the best quality, and which PE pipe or PPR pipe is better.
1. Which brand of PE pipe has good quality
1. Lesso, China Lesso has established an internationally leading and domestic research institute and a CNAS nationally recognized laboratory. Currently, China Lesso has nearly 1,000 patents owned and pending.
2. Jinde, established in 1999, is a large enterprise group approved and registered by the State Administration for Industry and Commerce.
3. Ruihe, China A manufacturer of high-end plastic pipes, it is the base of the industry-university-research alliance of East China University of Science and Technology. Is, Shanghai, Shanghai trademark, China's top 500 quality companies.
4. Melgu, taking the road of brand, technology, talent and internationalization, strives to build "Merge" into the world's outstanding plastic pipe brand.
5. Rifeng has a very strict quality assurance system. Rifeng products have passed the authority of more than 50 countries including the United States, Germany, and the United Kingdom, and have gained global recognition.
6. Peart has more than ten internationally advanced automatic pipe production lines, and has established complete testing equipment and quality assurance systems.
7. Jinniu, the company has been committed to the R&D and production of pipeline technology products and green and environmentally friendly products. It is a private high-tech enterprise dedicated to the R&D, production and sales of plastic pipes.
8. Zhongcai is one of the key chemical building materials manufacturers under the Zhongcai Group.
9. Weixing is a domestic listed company that mainly produces PPR water pipe products. Its PPR water pipes are moderately priced and have many sales sites.
10. Zhongjie, the company is a private high-tech enterprise specializing in the R&D and production of pipelines and the development of complete residential technologies. It develops and produces nineteen series of products in five categories, which can meet a variety of needs.
2. Which one is better, PE pipe or PPR pipe?
1. Raw materials
The raw materials of the two are different. The raw material of PE pipe is polyethylene. A kind of thermoplastic resin, it is odorless and smellless, has good chemical stability, is both heat-resistant and low-temperature resistant, and the PE pipe is very light and easy to construct. The raw material of PPR pipe is polypropylene, which is also heat-resistant, heat-insulating and corrosion-resistant. It is often used in hot and cold water pipes.
2. Cold resistance performance
PE pipe has more advantages in cold resistance performance. Both PPR pipes and PE pipes are widely used in drainage and water supply. The temperature requirements are also very important. The water temperature of PPR pipes can reach 70 degrees Celsius and minus 10 degrees Celsius. The water temperature of PE pipes can be 70 degrees Celsius, and the water temperature can be minus 30 degrees Celsius. Therefore, PE pipes are more suitable for cold environments and outdoor pipes, and are not easy to freeze and crack when the weather is cold.
3. Operation
Relatively speaking, PPR pipe is more convenient to operate. Both PPR pipes and PE pipes can be welded by hot melt welding. The acceptance temperatures of the two are 230°C for PE pipes and 286°C for PPR pipes. The flanging of PE pipes will be irregular, while the flanging of PPR pipes will be very round.
4. In terms of flexibility
In terms of flexibility, PE pipes have better elasticity than PPR pipes, but are relatively less rigid. PE pipes can withstand external pressure and are more suitable for use in sites with complex environments. The uses of PE pipes and PPR pipes are different, depending on the use environment. PE pipes are more suitable for use in urban water supply, chemical industry, etc., and are also suitable for farmland irrigation.
The above is the relevant knowledge shared by the editor about which brand of PE pipes has good quality, and which brand of PE pipes and PPR pipes is better. I hope it will be helpful to you. If you want to know more about PE pipes, please continue to pay attention.
