28. END AREA PREPARATION FOR PLAIN END AND THREADED PIPE

For the greatest part of all the inspections performed by Technical Industries, Inc., it is necessary that the pipe to be inspected be free of any foreign material that could degrade the inspection process. This is especially true for the end area inspection. The preparation process requires that the pipe be cleaned thoroughly for a distance of twenty-four inches (24") from each end of the pipe on both the external and internal surfaces. For threaded pipe, the completion of the process requires a specific compound applied to the threads and the protectors replaced and tightened to the appropriate torque.


29. CLEAN AND REDOPE THREAD

Threads are cleaned and specified compound is applied and the protectors replaced and tightened to the appropriate torque.


30. A.P.I. THREAD GAUGING

Includes the inspection of: Lead Gauge Twice, Thread Height, Taper, Triangle, Make-up, coupling length & pin run out gauge. (No cleaning.)


31. MRP THREAD GAUGING

MRP gauging includes a check of the pitch diameter and verification of the ovality on threaded pipe. 1) Several OD readings of box & pin to determine the highest reading & the lowest reading. 2) Calculation of the difference between the highest reading & the lowest reading. 3) Maintaining the tolerance within the specifications. (No cleaning.)


32. HARDNESS TESTING

Using special instruments, made by Rockwell or other manufacturers, hardness testing will be performed, and the instrument will be used according to manufacturer instructions and specifications to determine the proper hardness of the material.


33. ULTRASONIC WALL THICKNESS SPOT INSPECTION

According to manufacturer instructions and specifications, mechanical, or ultrasonic instruments operated by trained personnel perform wall thickness spot-check, and record readings.


34. DRY SEA BI-DIRECTIONAL TOOL JOINT INSPECTION

A magnetic field is induced into the tool joint using magnetic equipment in separate stages longitudinal and transverse fields. The transverse magnetic particle inspection is performed on the threads, and the longitudinal inspection is performed on the tool joint OD.


35. DRY SEA SLIP & CHAIN AREAS

The OD surface of the slip and chain areas of the pipe will be magnetized for magnetic particle inspection of transverse defects.


36. WET FLUORESCENT BI-DIRECTIONAL MAGNETIC PARTICLE TOOL JOINT INSPECTION

Pin threads & box will be magnetized and inspected for transverse defects, pin & box for OD longitudinal defects. The magnetic field will be oriented twice, once for longitudinal and another for transverse defects, and wet fluorescent fluid will be applied to locate fine defects.


37. WET FLUORESCENT MAGNETIC PARTICLE INSPECTION OF SLIP & CHAIN AREAS

The OD surface will be inspected for transverse defects using a magnetic field oriented for the application; wet fluorescent fluid will be applied to locate fine defects.


38. ULTRASONIC INSPECTION OF TOOL JOINT WELDS

Ultrasonic shear wave instrument will be calibrated, and operated by a trained inspector to detect transverse defects in the weld area of the tool joint.


39. ULTRASONIC BI-DIRECTIONAL END AREA SCAN OF SLIP & CHAIN AREAS

Ultrasonic shear wave instrument will be calibrated, and operated by a trained inspector to detect transverse and longitudinal defects in the slip & chain areas 12" past upset including tool joint weld.


40. ULTRASONIC TRI-DIRECTIONAL END AREA SCAN OF SLIP AND CHAIN AREAS

Ultrasonic shear wave instrument will be calibrated, and operated by a trained inspector to detect transverse and longitudinal defects in the slip & chain areas past the tool joint weld, and compression wave wall thickness instrument will inspect the wall thickness 12" past up-set area including tool joint weld.


41. TOOL JOINT OD MEASUREMENT

To determine OD at the tool joint shoulder width. In order to avoid down hole failure, the tool joint OD will be verified according to API RP7G Section 10


42. TOOL JOINT (Face) VISUAL EXAMINATION

Visual examination of tool joint face excluding threads or tool joint body, the face will be visually examined for damages that could cause seal washout, and eventually failure, inspection performed according to API RP7G Section 10.
