Magnetic Particle and Liquid Penetrant Inspection

Particle Inspection

Menges Roller Company is offering in-house testing and certification through Magnetic Particle and Liquid Penetrant Inspecting. These methods of inspection root out potential journal failures before they happen, allowing replacement and repair in a preventative, scheduled maintenance situation rather than the catastrophic failure that always involves expensive, unplanned downtime and damage to peripheral equipment, and can involve serious operator safety implications. Most journals, shafts and welds look fine to even the trained Mechanical or Maintenance Engineer, but can exhibit microscopic cracks caused by mechanical stresses the roll is subjected to, either ordinary or extraordinary.

Magnetic Particle and Liquid Penetrant Inspection under a magnetic field allows our highly-trained technicians to clearly determine that stresses have caused microscopic cracks that will lead to failure! We share our findings with your personnel and recommend the correct course of replacement or repair. Magnetic Particle and Liquid Penetrant Inspection offers you a high percentage of insurance and peace of mind that your journals and shafts will give you the years of service you expect, with the productivity, up time and high output you demand! Your rollers are critical to maintaining efficient operation- why wait for them to fail and disrupt your production schedule? Menges Roller is offering this inspection service to you at low cost, giving you the opportunity to prevent the kind of failure that always seems to happen at the worst possible time! Correct mechanical faults before they happen and keep control of costs and down time.

Inspection Types

Magnetic Particle Inspection

A nondestructive method of inspection for determining the existence and extent of possible flaws in ferromagnetic materials. Finely divided magnetic particles, applied to magnetized areas, are attracted to and outline the pattern of any magnetic leakage fields created by discontinuities.

Liquid Penetrant Inspection

A penetrant method of nondestructive testing used to locate defects open to the surface of non-porous materials. Penetrating liquid is applied to the surface, and under magnification the internal developer exhibits a color iridescence that defines the location, size and shape of any defects.

Fatigue Crack Growth Inspection

Fatigue Crack has a widely accepted correlation to applied load material constants with a high degree of certainty all cracks will propagate to failure. It's only a question of time.
