    • PURPOSE:To enable the easy mounting of a pipe perforated with multiple holes on a support base, by fixing the supports fixed to said pipe to the support base, welding the pipe to a ramose head while the test jacket is held fixed to the supports and flanges, and subjecting the pipe to a pressure resistance test. CONSTITUTION:Supports 6 are fixed by welding to a pipe 3 perforated with multiple holes, and part of a test jacket 4 is mounted between a flange 9 and one side of the supports 6, the other is fixed by welding to the other side of the supports 6. After the supports 6 are mounted and fixed to a support base 7, the pipe 3 is fixed by welding to a ramose head 2. If there is no abnormality in a weld zone 10 in a pressure resistance test, the cut line E of the jacket 4 is cut away. Since the pipe is fixed to the ramose head after fixing to the support base, there is no need for centering adjustment.
    • 目的:为了在支撑基座上轻松安装多孔孔管,通过将固定在所述管道上的支撑件固定在支撑基座上,将试管夹持固定在支架上,将管道焊接到拉头头; 法兰,并对管进行耐压试验。 构成:支撑件6通过焊接固定到穿孔多孔的管3上,部分测试护套4安装在凸缘9和支撑件6的一侧之间,另一个通过焊接固定在另一侧 支撑件6安装固定在支撑座7上后,管3通过焊接固定在拉头头2.如果在耐压试验中焊接区10没有异常,则切断线E 的夹克4被切掉。 由于在固定到支撑基座上之后将管固定到拉头头,所以不需要对中调整。
