ppr复合管-Gafloon(在线咨询)-随州ppr管

PPR管材料的耐水性用软化维卡系数表示。在采暖、高温热水、明敷安装、户外给排水管道应用中耐水性材料的软化维卡系数具有明显的优势。软化系数的大小，表明材料浸水后强度降低的程度，一般波动在0-1之间。软化系数越小，说明材料吸水饱和后的强度降低越多，ppr管，所以其耐水性越差。对于经常位于水中或受潮严重的重要结构物的材料，其软化系数不宜小于。受潮较轻的或次要结构物的材料，ppr复合管，其软化系数不宜小于0.75。软化系数大于0.80的材料，ppr管件，通常可以认为是耐水的材料。

In addition to the wall thickness， we can also distinguish from the color marking on the outer wall of PPR pipe. Color marking is also called coextrusion. The PPR hot water pipe is marked with red color marking，随州ppr管， the PPR cold water pipe is marked with blue color marking， and there are also manufacturers who do not need any color marking for PPR cold water pipe. 

ppr管的耐水性：

耐水管件的连接和防渗漏性能也是应该注意的。由于PPR管生产线经过对该管材特点的分析，设计生产了的剥铝工具，将铝层及PPR外层剥离掉，同样可以采用热熔承插的方法进行连接，消除了普通PPR管用铜管件连接容易渗漏的引患，更好的是管道实现其耐水性能。

The connection and leakage resistance of water resistant pipe fittings should also be paid attention to. Because of the analysis of the characteristics of the pipe， the production of the stripping tool is designed and produced. The aluminum layer and the outer layer of PPR can be separated. The hot melt socket can be used to connect the pipe. The common copper pipe used in PPR pipe is easy to leak， and the better is to realize the water resistance of the pipe.
