OSTI ID:6541015
The dewaxing valve comprises a ball and valve seat where the ball is on the upstream side of the flow of hot dewaxing fluid through a production pipe string to the well annulus. The design of the dewaxing valve is such that it can be readily attached to a production tube in the production tubing string by simply boring a hole in the side of the production tube and welding a supporting t-collar for the valve to the periphery of the side opening.
