工具和环
TOOLS AND RINGS
- 采用管件和管道制造商推荐的工具。所有工具必须能够实现完美圆周的压紧作业。
Use tools recommended by fitting and tubing manufactures.
All tools must make a full-circle crimp.
- 至少每天检查工具调节性能，如果必要就要进行调整。
Check tool adjustment at least daily, and readjust
as necessary.
- 采用美国尼伯科公司推荐的铜压紧环。
Use crimp rings of copper as recommended by NIBCO
INC.

将压紧工具钳夹精确放置在环上面，然后将工具手柄握到一起直到止动指示器完全封闭为止。操作完成后，用内卡规检查每个压紧环。如果内卡规上轻微的平面无法适配压紧环，则这个环没有实现正确压紧。剪切掉所有未成功压紧的环和管件，然后完全更换掉。
Center the crimping tool jaws exactly over
the ring, and bring the tool handles together until totally closed
to the stop indicator. Check each crimp ring with the caliper gauge
after completion. If the small flats on the gauge do not fit over
the crimped ring, the ring is undercrimped. Cut out any undercrimped
rings and fittings, and completely replace.
