摘要： A thermowell or the like is installed in a pipe or similar member without taking the member out of service by first welding an adapter to the surface of the member at the point where the thermowell is to be installed, connecting a gate valve and hot tapping machine to the adapter, drilling a hole in the member through the open gate valve, withdrawing the drill and closing the valve, replacing the drill in the hot tapping machine with the thermowell, opening the gate valve, and installing the thermowell through the open valve. The adapter having a taper internally threaded portion, distal from the ends of a conduit therethrough.
