Purge Test 12Cr1MoV Target Plate Device High Pressure Target Plate Shaft Aluminum Target Plate

The working principle of the target board:

The target plate device is a device used to fix the target plate. The target plate is a metal plate that is manufactured according to the material and size and is used to inspect the torch.

The target plate is installed in the temporary exhaust pipe (or at the exhaust port) at the end of the purged pipe. The material of the target plate can be made of aluminum plate. Its width is about 8% of the inner diameter of the exhaust pipe and the length runs through the pipe. For the inner diameter, under the premise of ensuring the blowpipe coefficient, the target board should be replaced twice for inspection. The particle size of the impact spot on the target board is not more than 0.8mm, and the visible spot is not more than 8 points, and the purging is considered qualified.
