The Magnetic Particle Field Direction Pie Gauge manufactured by NDE FLAW TECH INDIA is a precision-engineered magnetic field verification tool designed to evaluate the direction and adequacy of the magnetic field generated during Magnetic Particle Testing (MT/MPI). It is widely used to confirm that the applied magnetic field is correctly oriented to detect surface and near-surface discontinuities in ferromagnetic materials, thereby improving inspection reliability and ensuring compliance with established inspection procedures.

The Pie Gauge is an essential accessory for magnetic particle inspection, particularly during inspection procedure qualification, equipment setup, field verification, and operator training. It consists of multiple precisely manufactured radial discontinuities arranged in a circular pattern, enabling inspectors to determine the direction of the magnetic field by observing which artificial discontinuities produce magnetic particle indications.

The magnetic field must be approximately perpendicular to a discontinuity to achieve maximum indication sensitivity. The Pie Gauge provides a quick and reliable method of confirming magnetic field orientation before commencing production inspections, reducing the possibility of undetected defects due to improper magnetization.

Manufactured from premium-quality ferromagnetic steel using precision machining processes, the Pie Gauge offers excellent dimensional accuracy, repeatable inspection performance, and long operational life. The robust construction ensures reliable performance during repeated field and laboratory use while maintaining the accuracy required for inspection verification.

The Magnetic Particle Field Direction Pie Gauge is extensively used by NDT service companies, oil & gas industries, petrochemical plants, fabrication workshops, power generation facilities, pressure vessel manufacturers, pipeline contractors, educational institutions, and quality assurance departments. It is suitable for both visible and fluorescent magnetic particle inspection methods using wet or dry magnetic particles.

As an OEM manufacturer specializing in NDT calibration standards and inspection accessories, NDE FLAW TECH INDIA manufactures Pie Gauges in standard configurations as well as customized sizes and designs to meet specific customer and project requirements.
