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：将通过现有服务线向接收者供给气体的气体主体的更换方法包括：将第一抽头T形件连接到新的气体主体，并将第二分接开关连接到与下游接收器通信的现有服务线路。第一和第二抽头三通的分支通道通过连接导管流体连接在一起。然后，新的气体主体与第一个三通进行攻丝，使得气体从新气体主体流入连接导管直到第二个三通。所有的空气都从第一和第二个三通之间的连接导管排出，然后将现有的服务线与第二个发球台分接，以便通过现有的维修线和连接管道将气体供应到接收器。然后终止从旧主机向接收者的气流。第二个发球台是一种特别配置的攻丝三通，专门用于从连接导管排出空气，将第一和第二个三通相互连接。这个发球台还利用一个非圆柱形的孔来保持要被攻丝的管道，以防止在攻丝操作期间导管的塌缩。

摘要： A riser assembly is provided for transmitting gas from a buried line to a meter manifold. The riser assembly includes an adapter having a mounting structure at one end for connection to a manifold and having an opening at an opposite end. An inner casing has a first end received through the opening and a second end extending therefrom for connection with an associated buried line. A seal assembly is interposed between the inner casing and the adapter for sealing therebetween. A gripping assembly holds the inner casing in the adapter. A protective tubular assembly is received over the inner casing. The tubular assembly has a first end received in the opening and a second end extending therefrom a dimension sufficient to cover the inner casing above ground. The protective tubular assembly includes a steel liner received over the inner casing for protecting the inner casing, an anticorrosive coating received on the steel liner and a plastic jacket received over the coating and the liner for providing a protective barrier thereto.

摘要： A connector adapted for use with an associated fluid line includes a connector body having a passage dimensioned to receive the associated fluid line and a capturing member supported on said connector body. The capturing member is suitable for retaining the associated fluid line in the passage. A sealing member is disposed within the passage and is suitable for forming a fluid-tight seal between the connector body and the associated fluid line. A stiffening member is disposed within the connector body along the passage, and an indicator is disposed within the connector body and is adapted to indicate that the associated fluid line has been received a predetermined distance into the passage.

摘要： A valve operable with an associated fluid delivery system having fluid flow therethrough includes a housing, a valve body and a resetable excess flow valve. The housing has a first passage and the valve body is disposed along the first passage and including a wall at least partially defining a second passage. The excess flow valve is supported along one of the first and second passages. The valve body is displaceable between a first position permitting flow through the second passage and a second position substantially shutting-off fluid flow and resetting the excess flow valve.
