Do you know what kind of compressed air piping is used?

Pipe bracket, support and parts in the rust and dirt removal brush anti-rust paint twice, gray finish paint. The welding of support and hanger shall be performed by qualified welders and shall not have any defects such as leakage welding, underwelding or welding cracks. When welding the pipe and the bracket, the pipe shall not bite the edge or burn through. The circumferential weld of the pipe shall not be placed on the bracket and shall not be less than 200 mm away from the edge of the bracket.

Compressed air pipe thread connection, each branch pipe should be near the threaded connection of valve repair parts such as set up a union, in order to facilitate maintenance and repair, design pressure is greater than 1.0 MPa compressed air pipeline should be in after the installation of sampling radiographic inspection, sampling rate is not lower than 5%, the quality is not lower than Ⅲ level.

Compressed air is mainly used to drive pneumatic tools or equipment spray paint to play a role in transmission and atomization is also the technician wearing air supply mask breathing gas source. Compressed air contains oil particles and oil vapor, condensed water, suspended material metal debris and organic gas and other impurities.

According to the manufacturer of the compressed air pipeline, after the installation of the power pipeline, the strength test should be carried out on the pipeline system. When the pressure test is adopted, the test pressure of the low-pressure system is 1.15mpa and that of the high-pressure system is 1.61mpa. The test medium shall be dry and clean air. Prior to the test, consent shall be obtained from the construction unit. At the same time, safety protection and isolation measures shall be taken during the pressure test.

Compressed air pipe selection: compressed air pipe commonly used for seamless steel tube. Valve, pressure reducing device, oil and water discharge device, compensator, valve and meter are installed in the pipeline system. All of them are selected and processed according to the design drawing.
