Maximum flow capability provided by all sizes of HOKE Gyrolok Dielectric tube fittings.
The unique value and performance offered by HOKE Gyrolok.
Application
Commonly used in the Natural Gas Transmission industry, the Dielectric Fitting will prevent current flow resulting from Impressed Current Cathodic Protection Systems, static electricity or even lightning strikes, from reaching sensitive monitoring station equipment.
Impressed Current Cathodic Protection Systems involve the application of a low voltage, low amperage direct current to a pipeline and eventual transfer of corrosive effects to a typically underground anode bed.
If the current flow is not interrupted before reaching the monitoring station critical equipment could be damaged or rendered inaccurate.
By installing HOKE’s Gyrolok Dielectric Tube Fitting on impulse lines between the pipeline and the monitoring station, current flow is interrupted while full fluid flow is permitted.
