For most specialty gases, CTFE is recommended over PTFE because it is less permeable to oxygen and moisture, and evidences less cold flow.
对于大多数特种气体,推荐使用CTFE,而不是PTFE,这是因为CTFE对氧气和水蒸汽的渗透性更差,冷变形也较小。
Thus, torque wrenches should be used for tightening DISS connections. The recommended tightening torque is 35 foot-pounds with a nickel DISS washer and 12 to 15 foot-pounds for a CTFE washer.
因此,应该使用转矩扳手来上紧diss接头。推荐的上紧转矩对于镍DISS垫圈是35英尺-磅,对于CTFE垫圈是12到15英尺-磅。
