VCR接頭如果沒有擰到位，就有可能產生泄漏，即便有可能當時不漏，但會成為運行后的隱患。因此小編有請教一些施工經驗比較豐富的專門做高純氣體管道的工程師，他們說最好擰1/4 圈，這樣比較保險，否則容易有泄漏隱患。因此建議施工時還是擰 1/4 圈。現場管理人員可以通過如下兩種方法進行檢查：

　　If the RVCR joint is not screwed in place, there may be leakage, even if it may not leak at that time, but it will become a hidden danger after operation. Therefore, small make up have to consult some of the construction experience more rich specifically to do high purity gas pipeline engineers, they said that it is best to twist a quarter of the ring, so more insurance, or easy to have a hidden danger of leakage. Therefore, it is recommended to screw 1/4 turn during construction. Field managers can conduct inspections in the following two ways:

　　（1）檢查VCR接頭上的標記，看是否擰了1/4圈；

　　（2）通過內螺紋螺母上的泄漏測試孔（Test Port）進行測試。

　　方法（1）簡單易行，隨時可以檢查。但前提是工人施工時必須做好標記，否則沒法檢查。方法（2）雖然很可靠，但需要專門的儀器和設備，而且要更多的人力、物力，因此要根據項目的具體情況決定是否采用，通過內螺紋螺母上的泄漏測試孔還可以檢查是否安裝了墊片。

　　(1) check the mark on the VCR joint to see if 1/4 turn is screwed;

　　(2) Test through the Test Port on the inner thread nut.

　　Method (1) is simple and can be checked at any time. But the premise is that the workers must do a good job of marking construction, or can not be checked. Method (2) although very reliable, but requires special instruments and equipment, but also more manpower, material resources, so according to the specific circumstances of the project to decide whether to use, through the internal thread nut leakage test hole can also check whether the installation of gaskets.
