FULL WAVE DC DRILL TUBE END-AREA MAGNETIZING UNITS
High power coils for detection of surface and subsurface flaws
Meets EXXON SPECIFICATION DS1
FOR SEA INSPECTION OF DRILL TUBES
These Powerful coils are made to detect I.D. flaws in thick walled drill tubes –they produce at least 440 gauss at the center of the coil
The PITCO system consists of a power supply and interchangeable coils. The power supply is available or without demagnetization. Interchangeable coils are available from 8 to 16” ID (200 to 400 mm) diameter.
The control panel has a digital, backlit meter and Variac Control and requires 30 amp 220 VAC service.
The coils are ruggedly built for reliability in rough field conditions. 13,000 turns of 12 gauge aluminum magnet wire is wound on an aluminum frame and potted with epoxy for electrical safety and cool operation. In addition, the coil is grounded to the power supply for operator safety. Coil weight varies from 42 to 60 pounds depending coil size. Each coil is equipped with two handles for manual operation or mounting.
The MAG/DEMAG Power supply is a dual current DC power supply which allows magnetization for inspection and demagnetization of the pipe after inspection. Current is monitored with a backlit digital meter. Magnetizing and demagnetizing current are separately adjustable. The control unit is grounded to both AC ground and the coil for safety. The power supply is also available without the demagnetizing mode.
