摘要： A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee. All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees. This tee also utilizes a non-cylindrical bore for holding the conduit to be tapped to inhibit collapsing of the conduit during tapping operations.

摘要翻译：一种替换通过现有服务线路向接受者供应气体的气体主体的方法包括将第一攻丝三通连接到新气体主体并将第二攻丝三通连接到与下游接受器连通的现有服务线路。第一和第二攻丝三通的分支通道通过连接导管流体连接在一起。然后用第一个T形管将新的气体主管塞入，以便气体从新的主管路流入连接管路直至第二个T形管。所有空气都从第一和第二三通之间的连接导管排出，然后用第二球座轻敲现有的服务管线，以便通过现有的服务管线和连接导管将气体供应给接受者。然后终止从旧主机到接收者的气流。第二个三通是专门配置的攻丝三通，特别适用于从连接第一和第二三通的连接导管排出空气。这种三通还利用一个非圆柱形孔来夹持导管，以便在攻丝操作期间防止导管的塌陷。
