The corrugated pipe is a tubular elastic sensing element formed by connecting foldable corrugated sheets along the folding and stretching directions. The bellows is widely used in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thinner pipe wall and higher sensitivity, and the measuring range is tens of Pa to tens of megaPa. The open end is fixed, the sealed end is in a free state, and the elasticity is increased by using an auxiliary spiral spring or reed. When in operation, the movable end is stretched along the length direction of the pipe under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows often in combination with displacement sensors constitute a pressure sensor that outputs an electrical quantity, sometimes also serving as an isolating element. The bellows has a lower response speed than the bourdon tube because of the large volume change required for expansion. The bellows is adapted to measure low pressure.

The corrugated pipe has thinner pipe wall and higher sensitivity, and the measuring range is tens of Pa to tens of megaPa. In addition, the bellows may also serve as a sealing and isolating element separating the two media or preventing unwanted fluids from entering the measuring section of the device. It can also be used as a compensation element, compensating for temperature errors of the instrument with its volume variability. Sometimes also as a two-piece elastic coupling joint or the like. The corrugated pipe can be divided into a metal corrugated pipe and a nonmetal corrugated pipe according to the constituent materials; can be divided into single layers and multiple layers according to structures. Single-layer bellows are used more. The multilayer corrugated pipe has high strength, good durability and small stress, and is used in important measurement.
