WHAT ARE THE CLASSIFICATIONS OF CORRUGATED STAINLESS STEEL HOSE BY APPLICATION?

　Corrugated Stainless Steel Hose is classified by use: mainly including metal corrugated pipes, corrugated expansion joints, corrugated heat exchange pipes, diaphragm membrane boxes, etc.

　　Metal bellows

　　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.

　　Its structure is a tubular elastic sensitive element formed by foldable corrugated sheets connected in the direction of folding and stretching. Its open end is fixed, the sealed end is in a free state, and 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.

　　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 have a thinner wall and higher sensitivity, and the measurement range is from tens of Pa to tens of MPa.

　　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.
