Diaform LLC has everything you need for high-quality capillary control. Capillary flaw detection is a flaw detection method based on the penetration of certain liquid substances into surface defects of the product under the action of capillary pressure, as a result of which the light and color contrast of the defective area increases relative to the intact one. Distinguish between fluorescent and color methods of capillary flaw detection. In most cases, according to technical requirements, it is necessary to identify such small defects that it is almost impossible to notice them during visual inspection with the naked eye. The use of optical measuring devices, for example, a magnifying glass or a microscope, does not allow detecting surface defects due to insufficient contrast of the image of the defect against a metal background and a small field of view at high magnifications. In such cases, the capillary control method is used. During capillary inspection, indicator liquids penetrate into the cavities of surface and through discontinuities of the material of the objects of control, and the resulting indicator traces are recorded visually or using a transducer. Capillary testing is carried out in accordance with GOST 18442-80 “Non-destructive testing. Capillary methods. General requirements." A necessary condition for detecting defects such as discontinuity of the material by capillary methods is the presence of cavities free from contamination and other substances that have an exit to the surface of objects and a depth of propagation that significantly exceeds the width of their opening. Capillary methods are subdivided into basic ones, using capillary phenomena, and combined ones, based on a combination of two or more non-destructive testing methods that are different in physical essence, one of which is capillary testing (capillary flaw detection). Purpose of capillary inspection (capillary flaw detection) Capillary flaw detection (capillary inspection) is designed to detect invisible or weakly visible with the naked eye surface and through defects (cracks, pores, cavities, lack of penetration, intercrystalline corrosion, fistulas, etc.) in objects of control, determination their location, extent and orientation along the surface. Capillary methods of non-destructive testing are based on capillary penetration of indicator liquids (penetrants) into the cavities of surface and through discontinuities of the material of the test object and registration of the resulting indicator traces by a visual method or using a transducer. Application of the capillary method of non-destructive testing The capillary method of testing is used to control objects of any size and shape, made of ferrous and non-ferrous metals, alloy steels, cast iron, metal coatings, plastics, glass and ceramics in power engineering, aviation, rocketry, shipbuilding, chemical industry, metallurgy, in the construction of nuclear reactors, in the automotive industry, electrical engineering, mechanical engineering, foundry, stamping, instrument making, medicine and other industries. For some materials and products, this method is the only one for determining the suitability of parts or installations for work. Capillary flaw detection is also used for non-destructive testing of objects made of ferromagnetic materials, if their magnetic properties, shape, type and location of defects do not allow the magnetic particle method to achieve the sensitivity required by GOST 21105-87 and the magnetic particle control method is not allowed to be used according to the operating conditions of the object. A necessary condition for detecting defects such as discontinuity of the material by capillary methods is the presence of cavities free from contamination and other substances that have an exit to the surface of objects and a depth of propagation that significantly exceeds the width of their opening. Капиллярный контроль используется также при течеискании и, в совокупности с другими методами, при мониторинге ответственных объектов и объектов в процессе эксплуатации. Достоинствами капиллярных методов дефектоскопии являются: простота операций контроля, несложность оборудования, применимость к широкому спектру материалов, в том числе к немагнитным металлам. The advantage of capillary flaw detection is that with its help it is possible not only to detect surface and through defects, but also to obtain valuable information about the nature of the defect and even some reasons for its occurrence by their location, length, shape and orientation on the surface (stress concentration, non-compliance with technology etc.). Organic phosphors are used as indicator liquids - substances that give a bright self-glow under the influence of ultraviolet rays, as well as various dyes. Surface defects are detected with the help of means that allow removing indicator substances from the cavity of defects and detecting their presence on the surface of the tested product. news September 24, 2014 September 1, 2014 a separate subdivision was opened in the city of Nizhny Novgorod at the address Moskovskoe shosse, 17, building 1, office 46.
