Stainless steel bellowsIt is a flexible internal pressure pipe fitting, which can make up for the mutual displacement of pipes, machinery and equipment connections, absorb vibration energy, reduce vibration and eliminate noise. It is installed in the liquid transportation system and has flexibility, quality, and corrosion resistance., Fatigue resistance, high temperature resistance and low temperature resistance.

The stiffness of the stainless steel bellows is the load value required by the metal bellows or other elastic parts to generate unit displacement, which is called the stiffness of the parts, usually expressed by "k. If the elastic properties of the component are non-linear, the stiffness is no longer constant, but changes with increasing load. Nominal stiffness The stiffness provided in the elastic member design calculation is called the nominal (or rated) stiffness. Measurement stiffness and error of components. In particular, elastic elements with non-linear elastic properties. The nominal stiffness represents the stiffness at a point on the curve and should be considered carefully. In general, it is not recommended to use the design calculation value directly for the nominal stiffness. Instead, the corrected value of the product prototype test should be used. Stiffness tolerance is the allowable distribution range of stiffness when testing elastic member groups. For the same elastic member, the rigidity of each member of the stainless steel metal hose is different and has a dispersion range. In order to ensure the performance of parts, it is necessary to limit the stiffness distribution range. The rigidity tolerance requirement of the elastic sensitive element is limited to/-5% of the nominal value. Bellows elastic elements for general engineering can limit the stiffness tolerance within/-50%.

What is the connection method of stainless steel bellows?

　　Stainless steel bellowsThe connection method is divided into flange connection, welding, threaded connection, quick connector connection, small diameter metal hose is generally divided into threaded and quick connector connection, large diameter is generally divided into flange connection and welding.

Stainless steel hose material: SUS301/SUS304 inner diameter 4mm-10mm polishing treatment.

Stainless steel hose uses: automation instrument signal tube, automation instrument wire protection tube precision optical scale line, industrial sensor, electronic equipment line protection tube; power line safety protection, heat meter capillary protection and internal support of hollow core high-voltage optical cable.

Stainless steel hose characteristics: good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile resistance, water resistance, and good electromagnetic shielding performance. Stainless steel hose can be freely bent into different angles and radii of curvature, with the same smoothness and durability in all directions. The stainless steel hose is flexible between the pitch, good elasticity, no blockage, and good rigidity. There is a certain resistance between the sections and side buckles of the stainless steel through-line hose to prevent the hose from being damaged and the line laid inside the hose is exposed. The axial tension can bear more than 6 times of the nominal inner diameter.

　　Stainless steel bellowsFunctions:

Stainless steel corrugated pipe is mainly composed of corrugated pipe part and two ends of the joint part (one-time processing molding). The metal bellows tube blank adopts thin-walled stainless steel welded pipe for waveform processing, which has flexible, good internal temperature and pressure resistance. It is used in the transportation of air, steam, various industrial gases, water, oil, medicine and other fluid media. It plays an important role in the reciprocating motion of the relationship, the absorption of thermal expansion instrument, the absorption of vibration and the adjustment of pipeline center.
