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.

Abstract: A pipe insert (10) which in use is to provide a connection between at least two spaced pipe ends which are fixed relative to each other, said pipe ends each having first connection means (13) enabling the connection of an appliance between the pipe ends, the insert being intended in use to extend across the space between the pipe ends to replace the appliance and to provide a fluid tight interconnection between each pipe end and the abutting end of the insert and to provide substantially uninhibited fluid flow access between pipe ends.

Abstract: A pipe insert (10) which in use is to provide a connection between spaced pipe ends (11), the insert having at least two ends, the pipe insert being adjustable to be able to vary the relative displacement between the ends, each end having connecting means (12) adapted to provide a sealing interconnection between that end and the respective pipe end. A method of connecting at least two pipe ends is also claimed.
