Icenta launches turbine flow meter for Water Injection

07 January 2019

Icenta Controls, a British manufacturer of high quality turbine flow meters has introduced to its Metri Measurements range a customised High Pressure Turbine Meter made from exotic materials (Super Duplex & 6MO Body) for a Water Injection application.

Water injection is a method in the oil industry where water is injected back into the oil reservoir, to increase pressure and maximise production. Water injection also increases the recovery factor and maintains the production rate of a reservoir over a longer period of time.

A mix of chemical resistance materials were used to achieve application and product compatibility and long term service. 6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength making it the ideal material for Oil and Gas - Water Injection applications. Other materials were used for internal wetted parts. Each turbine rotor and support being machined from exotic materials.
