Abstract


Penetrating agents for penetrating test include penetrant, remover and developer. The capillarity abilities of the penetrant and developer are influenced by ambient temperature, which may affect the probability of defect detection. The behavior of penetrant agent under high ambient temperature has been researched and improved PT procedure has been made and performed based on ASME and related codes and according the features of the units. Some potential defects were detected subsequently.

Keywords


Penetrating material, High ambient temperature, Wetting phenomena, Surface tension.
