Nothing can be perfect, even if it is an excellent PE pipe manufacturer, the products it produces cannot be perfect, it can only be said that it meets the production standard 100%. Each industry has relevant production implementation standards, which filter out a large number of manufacturers without strength, and also ensure the quality of products in the market.
Although PE-RT pipes have been highly recognized by the market, this does not mean that the pipe has no shortcomings, just like PE-X pipes cannot be hot-melted, the raw materials are easy to adulterate, and the quality is difficult to control. PE-RT pipes The most deadly "short board".
The raw materials used to process PE-RT pipes must be high-temperature-resistant special PE raw materials, not ordinary PE. This kind of special material can only be formed by copolymerization of ethylene and octene at the beginning. Later, due to technological progress, this special material can be formed by copolymerization of ethylene and octene, or ethylene and hexene, ethylene and butene. . The complex raw material structure of PE-RT pipe not only ensures the extraordinary performance and quality of the pipe, but also objectively provides opportunities for those speculative drillers.
Some PE-RT pipe manufacturers take advantage of the above-mentioned characteristics of the pipe, and reduce production costs by adding linear low-density polyethylene to special materials during the processing of PE-RT pipes. There are also some manufacturers who directly use non-special materials for the production of PE-RT pipes. What's more, some companies actually use the raw materials used to process plastic films to process PE-RT pipes. These irregular processing behaviors make the quality of PE-RT pipes currently circulating in my country's HVAC market uneven and difficult to guarantee.
As the two most commonly used floor heating pipes in the floor heating pipe market, PE-X pipes and PE-RT pipes have their own advantages and disadvantages. In the eyes of industry insiders, no matter which kind of pipe is overly praised, it is unscientific.
