管道壁厚的增加直接帶來(lái)的性能的提升,，ppr管材廠家，比如：工作壓力增大,，ppr管材規(guī)格,，剛性增強(qiáng)，線性膨脹系數(shù)降低,，耐溫性能提-等,。
the increase of pipe wall thickness directly improves the performance， such as the increase of working pressure,，ppr管材,， the increase of rigidity， the decrease of linear expansion coefficient,， the improvement of temperature resistance&so on.
在給水管暗敷中試壓?jiǎn)栴},，若不試壓漏水將會(huì)很麻煩，好澆注地坪時(shí)給管道保壓,。漏水屬于問(wèn)題,，ppr管材，按照規(guī)范要求進(jìn)行-,，嚴(yán)把熔接關(guān),。
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， according to the specification requirements for pressure,， strictly control the welding quality.
