 一些廠家由于熔焊器放不正，PPR管材管件咨詢，熔焊時管端加熱就不正，連接易發生歪斜，以后在長時間的運行時，由于熱應力作用而出現泄漏。

Uk Gafloon Pipe Group Ltd，銷售PPR管、PVC管道等產品，詳情歡迎來電咨詢訪問。

Due to the improper placement of the welding device in some manufacturers， the heating of the pipe end is not correct during the welding， and the connection is prone to skew. In the long-term operation， the leakage occurs due to the effect of thermal stress.

Uk Gafloon Pipe Group Ltd sells PPR pipes，PPR管材管件制造， PVC pipes and other products. For details，寧波PPR管材管件， please call us.

PPR管格與管件連接端面必須清潔、干燥、無油。

用卡尺和合適的筆在管端測量并標繪出熱熔深度，熱熔深度應符合下表規定：

熔接彎頭或三通時，按設計圖紙要求應注意其方向，在管件和管材的直線方向上，PPR管材管件，用輔助標志標出其位置。

The connecting end face of PPR pipe lattice and pipe fittings must be clean， dry and oil-free.

Measure and plot the hot melt profundity at the pipe end with a caliper and a suitable pen. The hot melt profundity shall meet the requirements of the following table:

When welding elbows or tees， the direction could be noted according to the requirements of design drawings， and the place shall be marked with auxiliary marks in the straight direction of pipe fittings and pipes.

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。漏水屬于質量問題，按照規范要求進行打壓，嚴把熔接質量關。

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.
