MAGNETIC PARTICLE INSPECTION (MT)

ac-electromagnetic-yokeAC Electromagnetic Yoke: S/n # 2694

The Y-1 is an AC electromagnetic yoke and the new generation of light weight, ergonomically designed yokes that improve job performance and productivity by reducing operator arm and wrist fatigue when testing in tight, confined and overhead areas. Provides a portable means of creating AC magnetic fields for the detection of surface indications during magnetic particle testing.

Lightweight, less than five pounds, and ergonomic with a molded grip and trigger on/off switch, the Y-1 has impact and chemical-resistant construction. Includes a robust strain-relieved ten-foot cord and carrying grommet for convenience in field use.

White Contrast Paint

WCP-2:  provides a high contrast background to improve probability of detection and sensitivity during visible magnetic particle inspections. This bright, white contrast paint is applied prior to inspection so when non-florescent / colored magnetic particles are applied, the indications appear clearly against the opaque white background.

WCP-2 can be used with all types of colored and visible mag particles, including 7HF or 7C Black wet method particles, or #2 Yellow#8A Red or #3A Black dry method magnetic powders.

Benefits

  • Provides good background contrast
  • Fast drying
  • Convenient, ready to use formula

Specifications: ISO 9934

Applications Ideal for:

  • Field testing
  • Spot inspections
  • In-service inspections
White Contrast Paint
7HF

7HF

7HF is a highly-sensitive oil-based magnetic particle suspension aerosol for nonfluorescent (visible) wet method magnetic particle testing. 7HF provides clear, strong indications and are ideal for locating fine and medium discontinuities on finished parts. It is ideal for field testing, spot inspections and places where bulk processing is impractical.

7HF is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity. This process is ideal for remote inspections of tubing, piping, and large structures.

Benefits

  • Clear indications under visible light
  • Heavy particle buildup for quick detection
  • Great particle mobility
  • Protects parts and equipment against corrosion
  • Broad spray pattern provides even surface coverage over large areas
  • Superior surface wetting ensures higher probability of detection
