Electromagnetic Wall Loss Device Out Performs Gamma Radiation Tool to Locate Loss of Metallic Area in Oil Country Tubular Goods

摘要

Electromagnetics, when applied to new or used tubulars has proven to be more effective in locating loss of metallic area than any radioactive device. Production speeds are enhanced. Difficult LMA is clearly seen and reported via computer. 360° of the pipe's circumference is investigated with equal sensitivity and resolution to the cross sectional area. Electromagnetics eliminates the requirements for a radiation safety program, making EMI of LMA much more cost effective. In some cases initial equipment costs are cut by more than 50% when eliminating the rotating head on which the radioactive camera is mounted.
