Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component, or system without causing damage. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.
One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part.
Non-Destructive Testing Properties
Heliponents provides two Non-Destructive (NDT) services, Magnetic Particle and Fluorescent Penetrant testing. Both are conducted onsite by our certified NDT Inspectors and audited regularly by NADCAP.
Magnetic Particle Inspection (MPI) Services
An extremely sensitive nondestructive testing method for use on ferrous materials, magnetic particle testing can detect minute cracks open to the surface, and some subsurface discontinuities. The productivity and sensitivity of this method makes mag particle inspection an industry inspection standard requirement.
Magnetic particle examination for NDT is one of the more economical and speedy ways to ensure ferrous materials are safe and ready for use in the field. In simplified terms, this type of nondestructive inspection is performed by creating a magnetic field around the material being tested and then applying a carrier fluid which holds particles typically made up of iron oxide. Any defect in the surface or just under the surface of the subject material will distort the magnetic field surrounding it, causing the particles in the carrier fluid to be drawn to it. This attraction is easily detected and identified. If there are no flaws in the material, the particles within the magnetic field will remain evenly distributed throughout.
Liquid Penetrant (NDT) Testing
Also known as: Dye Penetrant Inspection (DPI), Liquid Penetrant Inspection (LPI), Penetrant Testing (PT), Fluorescent Testing
Liquid penetrant testing is one of the oldest methods of nondestructive testing still in use today because of its simplicity and remarkable sensitivity to locating very fine surface discontinuities. Used on ferrous, nonferrous, and even nonmetallic materials, dye penetrant inspection is the most common and cost effective of all NDT inspection methods.
• High Sensitivity
• Flaws are visually indicated on surface
• Appropriate for large & complex shapes
As the name implies, Liquid Penetrant testing involves a colored penetrating liquid that is applied to the surface of the material being tested. The liquid is drawn into defective areas in the material’s surface through capillary action and then drawn out to reveal itself to detection using UV lights or other methods, depending upon the type of penetrant and dye coloring used.
Heliponents provides a full range of economical liquid penetrant NDT services. We offer quick turn-around and a high degree of reliability.
