Star Pipe Drill Pipe Inspection
Ultrasonic NDE**
Our trade name for ultrasonic inspection of the slip/upset areas on drill pipe is called "Ultra-Scan." This equipment was first designed in 1992 by J.C. Houck. It was built, developed and perfected here at Star Pipe Service.
This inspection is to detect transverse flaws on the inside and outside surfaces of the tube or imperfections within the pipe body wall. The area inspected is 2 feet from the pin upset and 3 feet from the box upset. Not only does our precise Ultra-Scan inspection equipment find and pin point cracks; it will also locate pinholes, porosity, inclusions, mill defects, etc. for evaluation and prove-up.
When performing this critical inspection process, it is necessary to remove dirt, grease, and excessive rust from the outside surface of the areas to be inspected. Sometimes pressure washing, the use of wire brushes and in extreme cases sandblasing may be required to insure accuracy of inspection.
Ultra-Scan inspection is typically done in conjunction with a full-length drill pipe tube scan (CAT 5),
however it can be a stand alone inspection service upon request.
Don't fret! Star Pipe Service's expert inspector's can ease your conscience about your slip/upset areas. Give us a call.
