description:

Corrugated tube refers to a tubular elastic sensitive element connected with foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary coil spring or reed is used to increase the elasticity. When working, it stretches along the length of the pipe under the action of the internal pressure, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors whose output is electricity, and are sometimes used as isolation elements. Since the stretching of the bellows requires a large volume change, its response speed is lower than that of the Bourdon tube. Bellows are suitable for measuring low pressures.

Different of bellows:

Corrugated pipes mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm bellows and metal hoses. Metal bellows are mainly used for compensating pipeline thermal deformation, shock absorption, absorbing pipeline settlement deformation and other functions, and are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Corrugated pipes of other materials such as plastics play an irreplaceable role in media transmission, power threading, machine tools, home appliances and other fields.

Bellows: A pressure measuring elastic element in a pressure measuring instrument. It is a cylindrical thin-walled corrugated shell with multiple transverse corrugations. The corrugated pipe is elastic and can be displaced under the action of pressure, axial force, transverse force or bending moment. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is from tens of Pa to tens of MPa. In addition, bellows can also be used as sealing isolation elements to separate two media or prevent harmful fluids from entering the measuring part of the device. It can also be used as a compensation element, using its volume variability to compensate for instrument temperature errors. Sometimes it is also used as an elastic coupling joint of two parts, etc. Corrugated pipes can be divided into metal corrugated pipes and non-metallic corrugated pipes according to their constituent materials; they can be divided into single-layer and multi-layer according to their structure. Single-layer corrugated pipes are widely used. Multilayer bellows have high strength, good durability and low stress, and are used in important measurements. The material of bellows is generally bronze, brass, stainless steel, Monel and Inconel.
