When the pressure is over four kilograms, we can use slip on flanges. Flanges with different pressure will have different thickness, so we have to use different bolts accordingly.
Advantages: slip on flanges with light weight can not only saves space, but also have good sealing performance, thus there will not be leakage problems at the joints.
Disadvantages: can’t completely eliminate leakage problems because of the design. Dynamic joint. Things like thermal expansion, changeably cyclic loading will cause the movement of flange surfaces, affecting the function and integrity of flanges and finally cause leakage problem.
