Red Eye^® hot tap Insertion insertion and retraction technology allows insertion and retraction of a water-cut meter in a flowing pipeline. The meter uses patented optical sensor technology to accurately measure the full range of water cut (0 to 100%) in a commingled oil and water stream. Very high accuracy across all water-cut levels and easy installation and configuration make this unique meter suitable for numerous applications. The meter can be used in standalone mode to measure and report instantaneous water cut and in conjunction with the net oil computer (NOC) to perform timed production well tests, or as part of the Red Eye multiphase metering system (REMMS).

Product Requirements

The meter is designed for 6-to 12-in. (15.24-to 30.48 cm) piping that has an installed, 2-in. (5.08-cm) ball valve with a 600-lb (272.15 kg) flange ANSI certified for up to 1480 psi (102.7 bar). The distance between the top flange of the ball valve and the top of the piping must be approximately 16.25 in. (41.28 cm).

Red Eye® Hot Tap Insertion and Retraction Technology System Components:

A complete hot tap system consists of the Red Eye hot tap assembly, vertical spool assembly and hot tap insertion and retraction tool.

Hot Tap Assembly

The hot tap assembly includes a Red Eye head assembly and shaft extension. The shaft extension has a flange with inner holes that bolt to the vertical spool assembly after it is inserted into a pipeline. The outer holes on the flange attach to the adjustable shelf on the insertion and retraction tool, which is used to insert and retract the hot tap assembly.

Hot Tap Vertical Spool Assembly

The hot tap vertical spool assembly attaches to a 2-in. (5.08 cm) ANSI certified ball valve that has been installed on a flowing pipeline. The vertical spool assembly consists of a vertical spool with a pressure bleeder valve, an internal wiper, and packing material with a packing nut.

Hot Tap Insertion and Retraction Tool

The insertion and retraction tool is used to insert the hot tap assembly into or retract from the pipeline. It has a bottom shelf that is bolted to the outer holes on the bottom flange of the vertical spool assembly and an adjustable middle shelf that bolts to the outer circle of holes in the flange of the hot tap assembly.
