Chemical Injection Sub

The Chemical Injection Sub is designed to inject coolant or inhibitor fluids on to the coiled tubing while running into or out of the well.  The internal brass sleeve has small pin holes that provide an even coating of the fluid on the tubing.  Our 4 1/16" coolant / inhibitor injection sub comes with two 2.0" 1502 Weco port connections for connection with an injection line.  A check valve design is incorporated in the weco ports to prevent wellbore pressure from escaping into the injection line.

Chemical injection subs are available from 5000 PSI to 15000 PSI working pressures, for standard or sour service environments.
