It can be classified according to cross-sectional shape and material. Air pipe manufacturing stainless steel air pipe manufacturing is coated with sealing glue (such as neutral glass glue) in the gap such as bite joint, rivet joint, flange flange four corners. Before coating the sealing glue, the surface dust and oil stains should be removed. According to the cross-sectional shape, the air pipe can be divided into round air pipe, rectangular air pipe, flat round air pipe and many others, among which the round air pipe has the smallest resistance but the largest height size and is complicated to manufacture. Therefore, the rectangular air pipe is mainly used. According to the material, the air pipe can be divided into metal air pipe, composite air pipe and high polymer air pipe.
