(Non-Contact Metallurgical Stress Technology (MST
Non-contact MST can find out the condition of buried pipelines from above ground. This method is a complementary technique for the tools used to inspect pipelines according to NACE SP 0502-2008.
Advantages :
· Detecting metal deformation defects in buried or aboveground pipelines.
· Detecting defects irrespective of their orientation
· Estimating the level of stress in the defected areas of the pipeline
· Not interrupting or changing the pipeline operation
· Recording accurate location of defects using a sub-meter DGPS (up to 3Ocm precision)
· Capable BP being used for all operating pressures and a wide range of temperatures
· Capable of being used without any special preparation or additional equipment
· Capable of being used for pipeline with different size, bends, slopes, etc.
· Easy to operate
· Survey Speed of 4 Km per day Is achievable
· Accurate location RB data correlated with sub-meter DGPS (up to 50 cm accuracy
