密云ppr水管-Gafloon卡弗龙-ppr水管规格

在给水管暗敷中试压问题，若不试压漏水将会很麻烦，好浇注地坪时给管道保压。漏水属于质量问题，按照规范要求进行打压，严把熔接质量关。

The problem of pressure test in the concealed laying of water supply pipe will be very troublesome if there is no pressure test， so it is good to keep the pipe pressure when pouring the floor. Water leakage is a quality problem，密云ppr水管， according to the specification requirements for pressure， strictly control the welding quality.

ppr水管在连接时，无旋转地把管端导入加热套管内，家装ppr水管，插入到所标志的深度，同时无旋转地把管件推到加热管上，达到规定标志处。一般地可用心中默读数字法掌握加热时间，或观察管件、管材的加热程度，当模头上出现一圈PPR热熔凸缘时，即可将管材、管件从模头上取下进行下道工序。

When the PPR water pipe is connected， the pipe end is led into the heating sleeve without rotation and inserted to the marked depth. At the same time， the pipe fitting is pushed onto the heating pipe without rotation to reach the specified mark. Generally， the heating time can be mastered by reading numbers in heart， or the heating degree of pipe fittings and pipes can be observed. When a circle of PPR hot-melt flange appears on the die head， the pipe and pipe fittings can be removed from the die head for the next process.

三种PP管材中，ppr水管规格，管材抗冲击性能PP-R>PP-B>PP-H，管材热变形温度PP-H>PP-B>PP-R，管材刚 性PP-H>PP-B>PP-R，管材常温温度PP-H>PP-B和PP-R，管材耐化学腐蚀性PP-H>PP-B和PP- R。

Among the three kinds of PP pipes，ppr水管安装， the impact resistance PP-R > PP-B > pp-h， the thermal deformation temperature pp-h > PP-B > PP-R， the rigidity pp-h > PP-B > PP-R， the normal temperature pp-h > PP-B and PP-R， and the chemical corrosion resistance pp-h > PP-B and pp-r.
