The need for effective magnetic particle inspection of petroleum and natural gas industries tubular goods has been evident from the very beginning of oil well drilling and natural gas operations. The extremely high cost of failures in tubular goods continues to be a pressing problem for the petroleum producing and natural gas industries.
Tool joints and drill pipes are bonded utilizing inertia welding. These machines guarantee the most consistent and reliable weld available. After the welding process is complete, each piece of drill pipe is examined using the wet fluorescent magnetic particle inspection method. Once the drill pipe passes these tests, it is stamped to industry standard requirements and ready for finishing. The plain end pipe is upsetted, then the ends of the pipe are tested using the wet fluorescent magnetic particle inspection method. This inspection is carried out after the upsets are machined to the required dimensions. These tests guarantee that the drill pipe is free from defects.
Circle Systems has been providing the Petroleum and Natural Gas industries with our Mi-Glow® 810 for wet fluorescent magnetic particle inspection; CircleSafe® 820A, CircleSafe® 820AX and Mi-Glow® WCP for visible magnetic particle inspection in the field; and CircleSafe® 850A a red material that is used for visible magnetic particle inspection in the field, but is also further enhanced with black light.
