According to different wave types of bellows, they are mainly divided into two types: one is annular corrugated hose and the other is spiral corrugated pipe.


● spiral bellows


Spiral corrugated pipe is a tubular shell with spirally arranged corrugations. There is a spiral rise angle between two adjacent corrugations, and all corrugations can be connected through a spiral line.


● annular bellows


The annular bellows is a tubular shell with closed circular corrugations. The waves are connected in series by annular corrugations. The annular corrugated pipe is formed by processing seamless pipe or welded pipe. Restricted by the processing method, the length of single pipe is usually shorter than that of spiral bellows. The advantages of annular bellows are good elasticity and low stiffness.
