 XGT-A  Magnetic Particle Flaw Detector For Coupler Parts (Yoke)

Applicable scope

It is suitable for rolling stock 13,15,16,17# and other kinds of cast and forged yoke of the magnetic particle testing.

Features and Technical parameters

1. Magnetization mode which is combined rotating magnetic field with the induction method meet requirements of the yoke non-contact testing, avoiding the shortcomings of burning the work-piece electrified and working insecurity;

2.  Work-pieces vertically hanging to detect, reducing the transportation, loading work-piece and other chucking operations processes, which have a high efficiency

3. Pit structure makes the magnetic suspension returning very convenient, which reducing the waste of the magnetic suspension;
4. Magnetizing current is not equivalent attenuation, remanence meets the requirements;
5. Rated input power: 25kW;
6. Magnetization mode: Compound Magnetic Field;
7. Center conductor magnetization current: 8000A;
8. Longitudinal magnetization MMF: 8000AT;
9. Wellhead Size: 500 × 350mm;
10. Detecting sensitivity: Clearly displays the artificial faults of A1 standard test piece 15／50;
11. Residual Field: ≤0.3mT
