Magnetic Particle Inspection
A transversely oriented magnetic field is induced into the tube and iron powder applied to its outside surface. The powder is attracted to areas of variation in the magnetic field created by longitudinal or three dimensional defects, thus outlying the defects. Depth of the defect is then determined by grinding to the point of maximum penetration and measuring with an accurate depth gauge.
The tube is marked and classified as under API Spec.
Electro-Magnetic Standard Inspection (Sonoscope)
The tube is conveyed through the Sonoscope system where is magnetized and its circumference scanned for variations in magnetic field resulting from internal and external defects of transverse and three dimensional orientation.
Tubing is marked and the pipe is classified under API Spec.
Magnetic Particle Inspection for Special Upset Of High Strength Materials
This inspection locates injurious defects in the end areas of this material. Utilizing AC-YOKE magnetizing equipment longitudinal and transverse magnetic fields are induced into the end areas to detect defects regardless of orientation. Careful magnetic particle inspection is performed on the outside surface. Sand blasting is recommended for most sensitive inspection.
Magnaflux Inspection of End Areas
This inspection detects all defects extending to the surface and representing external damage or actual parting material inspection procedure.
API Drifting (Full Length)
Drifts according to API standards are applied to ensure specified I.D. dimensions.
Ultrasonic Wall Thickness Spot Test
Ultrasonic spot checks are made to determine the wall thickness along a helical path or in specified areas.
Thread Inspection With API Thread Gauge
Pins and coupling are measured for compliance with API Spec.
Visual Thread Inspection
Removal of scale, rust and other deposits with rotary metallic brushes
Removal of external scale rust and other deposits with metallic brushes
Hardness testers are employed to determine pipe hardness
Dimensional Inspection and Magnetic Particle Inspection Performed to API specifications of dimensions.
