タイトルまたは説明

The corrugated pipe refers to a tubular elastic sensing element connected by a foldable corrugated sheet along the folding direction. Bellows are widely used in instruments and meters. They are mainly used as measuring elements of pressure measuring instruments to convert pressure into displacement or force. The wall of corrugated pipe is thin, and the sensitivity is high. The measurement range is tens of Pa to tens of MPa. Its open end is fixed, the sealing end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity.
