是孤独还是孤毒 08-07 03:11

水管规格尺寸：常见的水管规格尺有：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。家装常用的ppr水管规格从ppr外径规格来算，常见的家装ppr规格有：20、25、32mm等规格。S3.2和S2.5热水管，这两种是家庭用的热水管道，有PPR标准型和PPR*型的，是用于暖气的话就用标准型PPR就可以了。S4和S5为冷热水管(PPR水管是分冷热水管的，管壁厚薄不一样，冷水管不能用做热水管，分辨冷热水管的简便方法是热水管上有一条红线标记，现在家装中很多都采用全部使用热水管。)。PPR管的管径家装中用到的主要是20mm，25mm两种(分别俗称4分管、6分管),其中4分管用到的更多些。一般总管用6分管，分管用4分管。以上这些都是一些水管的规格，买水管这前应该水电都会开好清单跟你说买什么样管，这边在来提醒一下：安装完水管以后一定要对它进行测压，金属及其复合管试验压力0.6MPa，稳压10分钟，管内压力下降应不大于0.02MPa，无渗漏;塑料管试验压力0.8MPa，稳压20分钟，管内压力下降应不大于0.05MPa，无渗漏。

您好，现在家装给水管一般都用PP_R管，家里用水量大进水管可用DN32.，分支管用DN25，支管用DN20，如果只是一厨一卫进水管可用DN25，排水管立管用PVC100的，坐便器用100的，其他支管用50的，厨房立管100或者75，支管用50的。

思念太荒凉 08-07 03:28

家装水管冷水管用25，热水管用20，主管25，支管20，也可以全用20的。冷热水管，PPR分冷水管和热水管，因为性能的原因，PPR热水管壁厚要大一些；如果是PE-RT管，性能好一些，就不分。
