Borealishas brought a major raw material innovation to the hot and cold water pressure pipe sector with the development of Beta-PPR™ RA7050. It delivers a clear improvement in the long term strength compared to current Polypropylene Random Copolymer (PP-R) materials, enabling PP-R to be even more competitive in the hot & coldwater house-installations.
PP-R materials were brought to the market more than 20 years ago and have been used predominantly for hot and cold water pipe systems. Due to its reliability, ease of installation, corrosion-resistance and other benefits, PP-R has made a major contribution to the growth of plastic pipes for heating and plumbing applications. However, over that time there has been no substantial advance in the performance of PP-R resins. The strength of the raw material, which is the basis for calculating the wall thicknesses of the pipe and determines the material consumption per unit length and the hydraulic capacity of the installed pipe system, has not changed until now.
“With this innovation, Borealis provides a technology breakthrough to the next generation of PP-R pipe materials and installation solutions. For a given building project, Beta-PPR allows the use of thinner and smaller pipes. We can use computer aided design (CAD) to determine the piping configuration and the savings from using Beta-PPR in plumbing systems,” says Robin Bresser, Marketing Manager, Borealis Pipe. “This breakthrough makes plastic pipe systems even more competitive versus old generation materials such as copper and steel,” he adds.
Beta-PPR提供的长期强度超过50％的显着改善，在现有标准中使用的70°C/50年的设计强度从3,21MPA移动到标准PP-R，可以在70°C/50年中进行逐步改变。到5MPA的Beta-PPR RA7050。对于水管工而言，关键的重要性是，与标准PP-R材料相比，内部管道直径更大会导致压力下降或更高的液压能力。欧洲杯足球竞彩
由于β-PPR的优异强度特性，给定的安装可以同时使用较薄的管道和更高的较小管道。这还可以使用较小的配件，生成用于绝缘材料的节省，并且由于所需的空间较小而允许更快的安装。欧洲杯足球竞彩Dendrit设计软件对典型房屋安装的影响建模（图1）。Beta-PPR材料的性能水平可提供更高的安全性，可在升高温度下提高欧洲杯足球竞彩氧化耐药性，并使管道系统安装更大的长期耐用性。

现在可以根据新的SKZ指南（Süddeutscheskunststoff-Ze欧洲杯足球竞彩ntrum，Würzburg，德国，德国，www.skz.de）认证由Beta-PPR材料制成的压力管系统，允许使用SDR 7.4个管道（尺寸基础：70ºC / c / c。50年的安全系数为1.5），而不是由标准PP-R制成的SDR 6管。因此，这项创新为北方人打开了与客户合作推销未来现代PP-R解决方案的机会。
