Corrugated pipe made by Krah machine

The corrugated pipe manufactured by the Krah machine refers to a tubular elastic sensitive element connected by foldable corrugated sheets in the direction of folding and stretching. The bellows manufactured by the Krah machine are widely used in instruments and meters. The main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force.

Basic information of bellows

The bellows made by the Krah machine have thinner walls and higher sensitivity, and the measurement range is from tens of Pa to tens of MPa. The open end of the bellows manufactured by the Krah machine is fixed, and the sealed end is in a free state. The auxiliary coil spring or reed of the bellows manufactured by the Krah machine is used to increase the elasticity. When the Krah machine bellows are working, it stretches along the length of the pipe under the action of the internal pressure, so that the movable end of the Krah machine bellows produces a displacement in a certain relationship with the pressure.

 The movable end of the Krah machine bellows drives the pointer to directly indicate the pressure. Krah machine bellows are often combined with displacement sensors to form a pressure sensor that outputs electricity and is sometimes used as an isolation element. Since the expansion of the Krah machine bellows requires a large volume change, the response speed of Krah machine bellows is lower than that of Bourdon tubes. Krah machine bellows are suitable for measuring low pressure.

Krah machine bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm diaphragms, and metal hoses. Krah machine metal bellows are mainly used to compensate for pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. Krah machine metal bellows are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy, and other industries. Krah machine corrugated pipes of other materials such as plastics play an irreplaceable role in the fields of media transportation, power threading, machine tools, and household appliances.

Krah machine bellows a pressure measuring elastic element in pressure measuring instruments. Krah machine bellows are cylindrical thin-walled corrugated shells with multiple transverse corrugations. Krah machine bellows are elastic and can produce displacement under the action of pressure, axial force, transverse force, or bending moment. Krah machine bellows are widely used in instruments and meters. The main purpose of the Krah machine bellows is as a measuring element of pressure measuring instruments to convert pressure into displacement or force. Krah machine bellows have a thinner wall, and Krah machine bellows have higher sensitivity, and the measurement range is tens of Pa to tens of MPa.
