8.6 Dye Penetrant Inspection - Developer Application: When the drying process is complete, the specimen is ready for the application of either dry or non-aqueous wet developer. When water-based wet developer is used, it is applied by flooding the surface to the wet specimen immediately after excess penetrant is removed.

liquid penetrant Liquid penetrant examination is a nondestructive method of revealing discontinuities that are open to the surfaces of solid and essentially nonporous materials. Indications of a wide spectrum of flaw sizes can be found regardless of the configuration of the workpiece and regardless of the flaw orientation. This lesson discusses surface preparation and penetrant application. Cleaning The effectiveness of liquid penetrant testing is based upon the ability of the penetrant to enter surface discontinuities. All paint, carbon, oil, varnish, oxide, plating, water, dirt, and similar coating must be removed before application of the penetrant. Application of Penetrant: The penetrant is then applied to the surface of the item being tested. The penetrant is allowed time to soak into any flaws (generally 5 to 30 minutes)is called dwell time. The dwell time mainly depends upon the penetrant being used, material being testing and the size of flaws sought. Dye penetrant inspection, also called liquid penetrate inspection or penetrant testing, is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline crac Penetrant Applicators Fast, consistent and even application of product or water These product applicators and water sprayers will help you speed up your penetrant inspection process by offering fast, consistent and even application of product or water to the part surface. 8.6 Dye Penetrant Inspection - Developer Application: When the drying process is complete, the specimen is ready for the application of either dry or non-aqueous wet developer.

Dye penetrant testing (PT) is a nondestructive method for crack detection in metals. PT is a process by which a liquid dye is applied to the surface to be inspected; this liquid dye seeps into cracks and other voids or depressions in the surface. The surface is then wiped clean, removing all of the dye from the surface. Whenever you need to perform liquid penetrant testing, Ardrox can offer high-performance chemicals. Water Washable Penetrants: 907PB Red Dye Penetrant for use in general engineering applications. Available in bulk or aerosol. 9704 Medium Sensitivity Fluorescent Penetrant for use on castings and machined components. Liquid penetrant testing (PT) is widely considered the most common non-destructive testing method, enabling our technicians to detect surface flaws such as hairline cracks, surface porosity and fatigue cracks on in-service components on a wide range of energy infrastructures.

Liquid Penetrant Testing Equipment Liquid penetrant testing units; Lighting for liquid penetrant testing equipment and light meters; Materials for liquid penetrant testing; Precautions in liquid penetrant inspection; Liquid Penetrant Testing Level II Topical Outline. Review Basic principles; Process of various methods; Equipment Aircraft inspection, propelled by the advances during World War II, was the engine behind the evolution of liquid penetrant testing. Advantages of LPI It is generally accepted that liquid penetrant testing has the following advantages: Sensitive to small surface discontinuities Nov 14, 2018 · Liquid Penetrant Testing can be applied to almost any non-porous surface. It does not work if the surface is porous or absorbs the penetrant. Similarly, the surface has to be clean. Liquid Penetrant inspection started in the 1890’s as the Oil and Whiting method. The Oil was actually kerosene and was used as the Penetrant. The whiting was chalk dust suspended in alcohol and was used as the developer. This method was utilized by the railroad industry to detect large cracks in their components. Penetrant Testing will detect casting and forging defects, cracks, micro shrinkage (or porosity) and leaks in new products, and fatigue cracks on in-service components. Since May 2007, Superior Joining Technologies has conformed to ASTM-E 1417 Standard Practice for Liquid Penetrant Inspection and was NADCAP Accredited in July 2008 . Penetrant testing utilizes a liquid with a high surface wetting ability and is applied to a material’s surface. Capillary action causes the liquid penetrant to “penetrate” into pores or cracks. Residual penetrant is then removed from the surface area followed by a developer.
