CAPILARY ACTION OR REVERSE CAPILARY ACTION
Liquid Penetrant Testing (PT) is based on Capillary Action
detect flaws on the surface of materials.
LPTis based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities.
It is based on capillary action. However, for a liquid to be a good penetrant, it must display a good wetting ability and have sufficient surface tension to cause capillary action.
Liquid Penetrant Inspection is mainly based on method of capilary action and material should be non-porous for inspection
LIQID PENETRATE TESTING is based on the principle on CAPILLARY action
Liquid penetrant testing is based on Capillary action
It is a dye penetrant way of nondestructive testing and its principle based on capillary action, where surface tension fluid low penetrates into clean and dry surface-breaking discontinuities
It is based on capillary action
