In-line Tee (ILT) Skids

inlineTeeImageThe Oil States In-line Tee (ILT) is an integrated equipment package that creates a branched line tie-in point along a pipeline.  By creating a tee along the pipeline, the operator can plan for tie-in points to fit future expansion plans.

The Oil States ILT system is integrated into a skid with necessary valves, lifting and support structures, mudmats and piping components. This facilitates simple installation into the line during launching and pipe-lay operations.

The upward-facing hub can be attached to with an Oil States collet connector when future expansion is required.
