Hose Fittings Selection Requirements-YUYAO SHUNDA VALVES & FITTINGS CO., LTD.

Hose Fittings selection requirements:

1. Composed of the metal pipe body, stainless steel wire mesh sleeve, and joint parts. In the marine pipeline system, it is mainly used in the connection between the pipeline and the equipment where the pipeline medium is oil or freshwater, which can compensate a certain relative displacement and achieve the effect of vibration and noise reduction. However, if the selection is improper, not only the effect of vibration isolation and noise reduction will not be achieved, but the damage of the metal hose will cause problems such as pipeline leakage and even equipment failure.

2. The selection of metal hose mainly includes the correct selection of parameters such as diameter, connection type, working pressure, temperature correction, minimum bending radius, and hose length. The diameter, connection type, and working pressure directly depend on the requirements of the piping system. Generally, there is no problem. It is worth mentioning that when selecting the hose design pressure (which should be greater than the system working pressure), it should not be too high, because As the pressure-bearing capacity of the pipe increases, its bending capacity is greatly reduced. The temperature correction and the minimum bending radius are fixed for the product and are given by the manufacturer. What we often have problems with is the selection of the length of the metal hose. Too long a hose will cause instability, increase flow resistance, and additional mechanical damage and vibration problems. If the hose is too short, it may not be able to achieve compensation and vibration reduction. Elimination of noise and other purposes will also cause excessive bending stress and affect life.
