Intermediate Jacking Method

PipeA long tube of clay, concrete, steel, metal, wood, etc., for conveying water, gas, oil or other materials. jacking method to redistribute the jacking force by the use of intermediate jacking stations.

Intermediate Jacking Station (IJS)

A fabricated steel cylinder fitted with hydraulic jacks, which is incorporated into a pipeline between two specially fabricated pipe segments. Its function is to provide additional thrust in order to overcome skin friction and distribute the jacking forces over the pipe string on long drives.

Internal Corrosion

Internal Erosion

Abrasion and corrosion on the inside diameter of the pipe or tubing due to the fluid that is being transported.

Internal Inspection

Means of ascertaining the condition of pipelines, either by visual inspection for man-entry size or by the use of remote control instrumentation.
