How to choose a good stainless steel joint

1.Fluid type and temperature (please select fluid type, material temperature and stainless steel joint sealing material), according to the fluid, suitable body material and sealing material



2. Liquid pressure (please choose the appropriate stainless steel joint to resist the fluid pressure), the fluid pressure is the key to choose the quick joint. The structure of stainless steel joints also varies with the compressive properties. The environment of the stainless steel joint (please select the structure and material suitable for the environment), combined with humidity conditions, dust conditions, easy corrosion, etc. The shape and size of the installation (please order the product after confirming the final shape and size) The stainless steel joint is mainly made of metal material bellows metal material bellows key to compensate the thermal deformation of the pipeline, shock absorption, digest and absorb the deformation effect of the foundation settlement of the pipeline, etc. It is widely used In petrochemical, instrument panel, aerospace, chemical, power engineering, concrete, metallurgy and other fields. The tubular elastic relatively sensitive element is composed of folded folded folded plates in the folded direction. The open end is fixed, the sealed end is optional, and the auxiliary compression spring or color plate improves the elasticity.






The availability of internal pressure along the length of the working pipe causes movement of the end of the body to induce some degree of pressure-dependent deflection. The magnitude of the pressure was immediately apparent by pushing the needle towards the end where the subject was moving. The bellows is usually combined with an angular displacement sensor to form a pressure sensor, the output of which is the amount of electricity used, and is sometimes used as a protective element.


Elastic element for measuring pressure in pressure measuring instruments. It is a cylindrical shell with multiple transverse corrugations and thick-walled folds. Bellows are elastic and can deform under pressure, axial force, lateral force or bending. Bellows are widely used in instrumentation equipment. It can be used as a precision measuring element in a pressure measuring instrument, converting pressure into displacement or force.

The bellows have thin walls and high sensitivity, and the detection range is from tens of MPa to tens of MPa. Bellows can also be used as seal protection elements, isolating or preventing harmful liquids from entering the precision measuring part of the machine. It can also be used as a compensation element to compensate the temperature error of the instrument with its volume plasticity. Sometimes also used as two-part elastic joints, connectors, etc.
