Abstract

A pipe insert providing a connection between pipe ends allowing fluid flow access between the pipe ends. The pipe insert having a central section with an internal thread that extends along the length of the central section and outer sections having inner and outer threaded ends. The inner threads allow attaching of the outer section into the central section so that the pipe insert may vary the relative displacement between the free ends of the pipe insert to correspond to the spacing between the pipe ends. The outer threaded ends having a releasably attaching connection to the outer section to provide a connection between the spaced pipe ends. The pipe insert is particularly useful during replacement of an appliance located between the pipe ends. The pipe insert is adapted to receive flow control and/or sensing element for measurement of fluid flow between the pipe ends.
