Overview
The magnetic yoke type Flaw detector has the characteristics of compact structure, reasonable layout, small size, light weight and convenient carrying. It is suitable for magnetic particle detection of surface and near-surface defects of ferromagnetic materials in various steel structural parts in electric power, metallurgy, petrochemical, machinery and other industries, boilers, Pressure Vessels, pressure pipelines and various types of welded structures. The Flaw detector is directly connected to AC for use, especially for hull weld inspection, steel structure weld inspection and internal operation of Pressure Vessel.
Features
1. Small size and light weight;
2. One-piece molding, comfortable feel;
3. Single-phase AC power supply.
Principle
The yoke type Flaw detector generates a magnetic field through an electromagnetic yoke, magnetizes a ferromagnetic material, and displays surface and near-surface defects using a magnetic particle detection method.
Applications
Electric Power, Metallurgy, Petrochemical, Machinery, Hull Weld Inspection, Steel Structure Weld Inspection, Pressure Vessel Internal Operation
Standards
JB/T7411-2012、ASTM E1444-05
Steps
1. Connect single-phase AC power supply AC220V 50Hz;
