LIQUID PENETRATETESTING TRAINING

LIQUID PENETRATETESTING TRAINING IN HYDERABAD

Liquid Penetrant Testing Training Hyderabad (LPT) or penetrant testing (PT), is a widely applied to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

The penetrant may be applied to all non-ferrous materials and ferrous materials; LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

Liquid penetrant testing is one of the  popular Nondestructive testing (NDT) methods in many industry. It is economical adapted, and requires minimal training when compared to other NDTmethods.

LPT check for material flaws open to the surface by flowing very thin liquid into the flaw and then drawing the liquid out with a chalk-like developer. Welds are the common component inspected, plate, bars, pipes, forging, and casting are also commonly inspected using liquid penetrant examination.

liquid penetrant examination has been called many names: penetrant testing (PT), liquid penetrant testing (LP), and dye penetrant testing (DP). The American Society for Nondestructive Testing (ASNT) uses the name liquid penetrant testing (PT). Lpt is another means of enhancing the capability of visual observation. It is suitable for use on smooth surfaces of all materials inclusive of magnetic as well as non-magnetic. It is limited to surface defects. Its impotence to indicate the depth or breadth of flaw should be kept in mind while selecting this method for particular application.

Use of LPT for porous materials is ruled out since the absorption into the pores would mask the presence of defects. A clean surface is a per-requisite as penetrant cannot enter in to the cracks that are filled with dirt, oil, or other forms of contaminant.

Size, shape, weight and number of work pieces to be inspected often influence the selection of a penetrant system. The desired extent of sensitivity and the cost are the most important factors in selecting a system.

LPT can also be used for leak testing. In this type, the component casting is filled with penetrant and developer is applied outside the surface.
