20. DRY SEA MAGNETIC PARTICLE FOR THREADED & COUPLED PIPE NON-CRITICAL APPLICATION
The dry special end area inspection is performed on ferromagnetic material. The area to be inspected must be thoroughly
cleaned before beginning the inspection process. After a visual thread inspection is performed, A.C. magnetic field, using
a yoke or other instrument properly oriented according to the inspection to be performed, is induced into the pipe. Dry
iron powder is applied to the area. Any accumulation of powder at the point of flux leakage, caused by an anomaly, will
be probed. Should the anomaly be insufficient for rejection of the material, the imperfection will be removed and the
area contoured.
21. DRY SEA MAGNETIC PARTICLE FOR PLAIN END PIPE CRITICAL APPLICATION
The dry special end area inspection is performed on ferromagnetic material. The area to be inspected must be thoroughly
cleaned before beginning the inspection process. After a visual inspection is performed, a DC magnetic field, properly
oriented according to the inspection to be performed, is induced into the pipe. Dry iron powder is applied to the area.
Any accumulation of powder at the point of flux leakage, caused by an anomaly, will be probed. Should the anomaly be
insufficient for rejection of the material, the imperfection will be removed and the area contoured.
22. WET SEA FOR THREADED PIPE FOR CRITICAL APPLICATIONS
This inspection process, using finely ground iron powder suspended in a fluid, is used to inspect the ends of ferromagnetic
tubular. The area to be inspected must be thoroughly cleaned before beginning the inspection process. This is followed by a
visual thread inspection. A magnetic field, whose direction is appropriate for the inspection being performed, is then
induced into the tubular. A bath with suspended fluorescent iron particles is then applied to the area viewed under an
ultraviolet lamp. Any anomalies found will be probed for depth. In the event the anomaly is insufficient for rejection
of the material, the anomaly will be removed and the area contoured.
23. WET SEA FOR PLAIN END PIPE FOR CRITICAL APPLICATIONS
This inspection process, using finely ground iron powder suspended in a fluid, is used to inspect the ends of ferromagnetic
tubular. The area to be inspected must be thoroughly cleaned before beginning the inspection process. This is followed
by a visual thread inspection. A magnetic field, whose direction is appropriate for the inspection being performed, is then induced
into the tubular. A bath with the suspended fluorescent iron particles is then applied to the area viewed under an
ultraviolet lamp. Any anomalies found will be probed for depth. In the event the anomaly is insufficient for rejection
of the material, the anomaly will be removed and the area contoured.
24. DYE PENETRANT SEA FOR THREADED PIPE
In the event that the material to be inspected is not ferromagnetic and an ultrasonic end area inspection is inappropriate,
the use of dye penetrant inspection may be employed. The material is first cleaned over the entire surface to be inspected.
A fluorescent dye of the proper type for the material will be applied. Inspection will proceed under ultraviolet light.
Anomalies found through this inspection will be probed and removed if their depth is insufficient for the rejection of the material.
25. DYE PENETRANT SEA FOR PLAIN END PIPE
In the event that the material to be inspected is not ferromagnetic and an ultrasonic end area inspection is inappropriate,
the use of dye penetrant inspection may be employed. The material is first cleaned over the entire surface to be inspected.
A fluorescent dye of the proper type for the material will be applied. Inspection will proceed under ultraviolet light.
Anomalies found through this inspection will be probed and removed if their depth is insufficient for the rejection of the material.
26. ULTRASONIC SPECIAL END AREA INSPECTION, TEN INCHES (10") EACH END NOT INCLUDING THREADS
Ultrasonic end area inspection is performed on material that is either non-ferromagnetic or where the customer is concerned
about imperfections that are not readily discernable with other inspection methods (i.e., laminations). The entire surface
area is scanned, for ten inches from the end of plain end pipe or from the last thread on threaded pipe, using the
appropriate transducer coupled to shear wave instrumentation. Imperfections found during the inspection process are
further probed to evaluate their severity. If the imperfection is not severe enough to cause rejection of the tubular
and it is removable, it is then removed and the area contoured. Includes preparation.
27. CLEAN AND VISUAL THREAD INSPECTION
Threads and shoulders are cleaned and visually inspected for service-induced defects, corrosion, mechanical, or manufacturing
irregularities. Thread compound is re-applied, and thread protectors re-installed, when provided.
