Install pipes every day, do you know the installation standards of compressed air pipes?

Learn and grow together with Dongfang Will compressor every day! Compressed air pipeline installation standards and pneumatic equipment engineering installation acceptance standards refer to GB5038-2006 general provisions of pipe and pipe, pipe and equipment connection shall not be strong. Before painting the compressed air carbon steel pipe, the surface of the rust, welding slag, burr, oil and water and other dirt should be removed. Before pressure test, the weld shall not be painted. The butt weld of the compressed air carbon steel pipe shall be argon arc welding or argon arc welding as the base and arc filling.

The appearance quality of the compressed air carbon steel pipe butt weld is not allowed to have cracks, pores, slag inclusion, melting spatter and non-penetration: the bite depth is less than 0.5mm, and the total length of the weld on both sides is less than 10% of the total length of the weld, and the height of the weld is less than or equal to 1+0.1b (b is the width of the weld), and is less than 3mm. Pipe cutting and pipe beveling should be mechanically processed. The end face of the incision should be flat, the end face should be perpendicular to the axis of the pipe, and the allowable deviation should be 1% of the straight diameter of the pipe and should not be greater than 2.0mm. The form and size of pipe welding groove should conform to the requirements of welding operation instructions, and iron chips and burrs should be removed after the groove processing.
