Improving corrosion inhibition
Spray pig helps offshore gauge success of corrosion inhibitor applications.
Injection or batching of corrosion inhibitor fluid is an essential part of a maintenance program aimed at reducing pipeline deterioration. Unfortunately, gravity often forces inhibitor fluid to settle along the bottom of the pipe, leaving the top vulnerable.
Designed to overcome gravity, the TDW V-Jet® VXP Corrosion Inhibitor Pig provides a more complete coating – and better protection – for all pipe wall surfaces. Mounted to the front of a special pig configuration, V-Jet pigs use bypass flow as a vacuum, literally sucking up residual corrosion inhibitor that has dropped to the bottom of the pipe wall and spraying it onto the inside top portion.
The V-Jet VXP corrosion inhibitor pig is designed for smaller pipeline diameters, from 4 inches through 12 inches. The V-Jet corrosion inhibitor pig is used in pipeline sizes 10 inches through 28 inches.
