管道壁厚的增加直接帶來的性能的提升，ppr管材廠家，比如：工作壓力增大，ppr管材規格，剛性增強，線性膨脹系數降低，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問題，若不試壓漏水將會很麻煩，好澆注地坪時給管道保壓。漏水屬于問題，ppr管材，按照規范要求進行-，嚴把熔接關。
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.
