A335 P11 High Temperature Alloy Steam Blowing Target Plate

A335 P11 High Temperature Alloy Target Plate Axis Power Plant Steam Pipe Purge

The target board is used to place the target board. Pay attention to the structure and technology of the target board, and have sufficient strength. Its structure should be simple, good sealing, flexible operation, and the exchange of the target board should be safe and convenient.
The commonly used target plate structure includes flange type, straight shaft type, tandem shaft type and frame type. The first three are internal test target plates, and the frame type is external test target plates.
The internal test target plate is installed in the purge link pipe or exhaust pipe, as close to the end of the purge pipe as possible, and on the straight pipe 4-6m away from the elbow.

When using the two-stage purging method, after the first-stage purging is qualified, the target plate should be removed for the second-stage purging. It is not advisable to install the target board at the second stage.
In order to inspect the blowpipe correctly, the target plate should be polished without visible marks.
After the installation of all equipment in thermal power plants, it is generally necessary to blow pipes through the boiler to purge the pipes with steam. The purpose is to remove the debris remaining in the equipment and pipes during the manufacturing, transportation and installation of the equipment and pipes, and to prevent the boiler from overheating during operation The blower and reheater block and break the pipe, and at the same time prevent debris from entering the steam turbine to cause damage to the blades and valves. Therefore, the boiler and the steam turbine need to be tested for trial operation before the safe operation of the boiler and the steam turbine. More valued equipment.

The working principle of the target board:

The target plate 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 target plate material 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. Inner diameter, under the premise of ensuring the blowpipe coefficient, the target board was replaced twice in a row 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 blowing is considered qualified.

Target board material:

The material of the target plate inside the target plate is aluminum plate, and the material of the outer shell is 12Cr1MoV. Other materials can be determined according to customer requirements.
Target board specifications:
According to the specifications provided by the customer, the target board interface (flange connection or flangeless connection)
