Penetrant testing principle and advantages

Image
 ›Penetrant Testing is one of the effective method for detecting surface flaws,. ›It can be used on Metals, non-metals, plastics, ceramics & Glass. ›Not suitable for Porous materials such as wood, bricks, concrete, & other non graded castings, sponge Qualification of Examination Personel ›Able to read a Jaeger Type No. 2 Standard Chart at a distance of not less than 12 in. (300 mm), ›Should be capable of distinguishing and differentiating contrast between colors used. ›These requirements shall be checked annually. ›Should clear the Examinations with percentage stated in ASNT SNT-TC-1A Basic Principle ›Capillary Action – Low surface tension fluid( dye) penetrates in to clean and dry defects open to the surface. Advantages of PT ›High sensitivity to small surface discontinuities. ›Vast application -metallic and nonmetallic, magnetic and nonmagnetic, and conductive and nonconductive materials may be inspected. ›Large areas and large volumes of parts/materia...

What is Non Destructive Testing ?

 Non Destructive Testing , NDT , is industrial method for analyzing the characteristics of material or finding the discontinuities in the material & Weld joints, without damaging the material. NDT is otherwise called as, Non Destructive Evaluation –NDE, Non Destructive Inspection (NDI) and it a quantitative analysis method. Whereas Destructive Testing is a Qualitative analysis method, to find the quality of the material such as Tensile strength, Elongation property, hardness value, Impact toughness, etc The above mentioned qualitative properties cannot be found using NDT methods. This is  because in order to find the mechanical properties, it is required to apply load on the material. The load deforms the material  making them not usable. But NDT Methods are used in such a manner, that the material can be reused after the testing. This area answer some of the FAQ Frequently asked Questions What is NDT? What is the use of NDT? What is Difference betw...

Liquid Penetrant Testing PT/LPT Inspection Service

Image
PT / LPT Liquid Penetrant Testing inspection  services are carried out for finding Surface defects, on almost any material except very rough or porous surface materials such as poor cast iron material. Advanced Quality Centre  offers India’s best NDT Inspection Service and we are the most trusted and reliable testing company. We provide Die Penetrant Testing Service, both visible and fluorescent method DP testings are carried out. What is Liquid Penetrant Testing? Liquid or Die Penetrant Testing DPT is a surface defect detection method. Penetrant Testing involves pouring die over the perfectly cleaned surface of the material  and the poured die is allowed to penetrate into the defects. The penetrant thus entered the discontinuities are exposed to developer and the developer sucks out the die and visual presents us the defects as bleed out. PT is generally carried out on any raw material, root weld, finished weld, repaired surface, machined surface or any mat...
