43. TOOL JOINT SHOULDER (Face) WIDTH

Measurement of the tool joint shoulder seal, to determine if it is wide enough, and within tolerance for further use.


44. TOOL JOINT WELDING DATE/GRADE MARK EXAMINATION

Performed on pin end only according to API RP7G Section 10.


45. TOOL JOINT CLEAN & VISUAL EXAMINATION

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.


46. TOOL JOINT PIN STRETCH INSPECTION

The joint pin is cleared and threads are visually verified to a hand held mechanical thread profile lead gauge, the inspection procedure performed by a trained inspector.


47. TOOL JOINT BOX SWELLING AND MEASUREMENT & COUNTER BORE Qc

A trained inspector will take measurement across the inside bore of the box and compared to API Spec. 7 for possible swelling indication.

48. RSC DIMENSIONAL INSPECTION OF CONNECTIONS

A trained inspector will visually inspect each end and verify tool joint OD & ID, tool joint length, bevel diameter, pin cylinder diameter, thread length, thread profile and hard band measurements. Dimensions to be recorded according to API RP7G Section 10. Does not include cleaning, buffing, solvent, compound, and environmental.


49. REFACING OF ROTARY SHOULDER CONNECTIONS

Technical Industries, Inc., provides trained inspectors with sand paper or lathe type re-facer for single shoulder connecton. Proprietary dual shoulder connection re-facer is available.


50. METAL STAMPING

Metal stamping includes the numbering of each joint, and the marking of the inspection company initials, month and year pipe inspected.


51. HEAVYWEIGHT DRILL PIPE INSPECTION DRY MAGNETIC PARTICLE INSPECTION FOR END AREAS

Dry magnetic particles applied according per Technical Industries, Inc. specifications Inspection Procedures for End Areas are 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 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.


52. HEAVYWEIGHT DRILL PIPE TOOL JOINT BLACKLIGHT INSPECTION

Inspection includes the visual examination and dimensional inspection of the connection, blacklight connection inspection according to Category 3-5. This inspection process includes, using finely ground iron powder suspended in a fluid, 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 orientation is appropriate for the inspection being performed, is then induced into the inspected tool. A bath with the suspended fluorescent iron particles is then applied and 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 if accessible will be removed and the area contoured.


53. DRILL COLLARS, KELLYS AND STABALIZERS, FULL LENGTH DRY MAGNETIC PARTICLE INSPECTION & MECHANICAL OPTICAL INSPECTION

Dry magnetic particles according to Technical Industries, Inc. specifications Inspection Procedures for Full Length excluding end areas is performed on ferromagnetic material. The outside surface of the tool is cleaned and visually examined for defects. The inside surface of the tool is examined with proprietary camera or special optical instrument for visible defects. The area to be inspected must be thoroughly cleaned before beginning the inspection process. After a visual thread 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 if accessible will be removed and the area contoured.
