High Contrast X-Ray Flaw Detector , Type D7 T7 Industry Radiographic Film
General Characteristics:
Type T7 industry radiographic film is a fine grain, high contrast, high radiation sensitive, high definition radiographic film made by using novel emulation technology. Designed for direct exposure or with lead screens. For exposure with lead screens using either X-ray or gamma rays.
The T7 radiographic film consider two fundamental factors of the nondestructive control (NC) - quality of the image and stability of properties.
Applications :
This film is suitable for different NDT applications such as: medium thickness heavy metals and alloys, fairly thick light metals and alloys, and also suitable for NDT of heavy metal parts having thick section when exposed with high-energy radiation. The film is especially suited to high temperature automatic processing. This product is compatible with international norms.
