Analysis on 5 Key Points of Stainless Steel Bellows

Bellows are novel in concept, practical in process, low in cost, reliable in performance, high in heat transfer efficiency, free from scaling, long in service life and low in thermal stress. Analysis on 5 Key Points of stainless steel Bellows;

1. Temperature. Working temperature and range of medium in hose; Ambient temperature when the hose is operating. At high temperature, the temperature corrected pressure shall be determined according to the working pressure temperature correction coefficient of metal bellows at high temperature to determine the correct pressure grade.

2. Media. The chemical properties of the medium conveyed in the hose determine the material of each part of the hose according to the corrosion resistance parameter table of hose material.

3. Pressure. According to the actual working pressure of the hose, check the nominal diameter of the corrugation and the pressure gauge to decide whether to use the stainless steel mesh sleeve type.

4. Dimensions. Nominal diameter of hose, selection of joint type (mainly flange connection, threaded connection, quick joint connection) and size, hose length.

5. Status. According to the state of the hose when in use and referring to the correct use and installation method of the metal hose and the optimal length of the hose during settlement compensation, the length calculation of various motion states of the hose and the factors such as the minimum bending times and the minimum bending radius of the hose, the hose length is correctly selected and correctly installed.
