首先必须包涵经济价值本身，经济价值是一个有力的体现，也是一个的内涵和生命力。Gafloon卡弗龙，注重打造，专注生产PP-R、PVC、地暖管等各种管材。
First of all, a brand must include the economic value itself, which is not only the most powerful embodiment of a brand, but also the connotation and vitality of a brand. Gafloon focuses on brand building and production of PP-R, PVC, floor heating pipes and other pipes.
ppr热膨胀性能
我们会使用冷水，也会使用热水;我们生活的环境也会发生一年的四季变化。所以的水管材料不应该是导热材料，应该是热膨胀系数较小，对环境温度和使用温度适应性较强。热膨胀系数过高也是漏水的原因之一。
Thermal expansion properties of PPR
We use cold water and hot water; The environment we live in also changes in four season of the year. So the water pipe material should not be thermal conductivity material, should be the coefficient of thermal expansion is small, the environmental temperature and use temperature adaptability is strong. High coefficient of thermal expansion is also one of the reason for water leakage.
ppr管材规格型号表
一般家用水管规格有DN15（4分管）、DN20（6分管）、DN25（1寸管）、DN32（1寸2管）、DN40（1寸半管）、DN50（2寸管）、DN65（2寸半管）、DN80（3寸管）、DN100（4寸管）、DN125（5寸管）、DN150（6寸管）、DN200（8寸管）、DN250（10寸管）等。
通常说的4分管是按英寸来说的，因此4分管就是1／2英寸（4／8＝1／2），而一英寸＝25．4mm，所以4分管的内径就是25．4／2＝12．7mm，而这就是通常所说的DN15水管的内径。
