Pressure gauges typically include a pressure gauge bend when measuring steam, but that part connecting the pressure gauge to the pipeline is actually the pressure gauge bend (also commonly referred to as a bend). Generally, when we purchase it, we call it a buffer pipe. The pressure gauge bend comes in two common forms: one is a circular bend, and the other is a U-bend.

The primary function of pressure gauge elbows

The gauge bend is used to protect the internal transmission mechanism of the gauge from damage caused by medium temperature and medium corrosion. It is typically required when the medium has some corrosive properties, or when the medium temperature exceeds 60℃. If the pressure gauge is installed in a clean drinking water system, a gauge bend is not necessary.

2. The pressure gauge bend serves to reduce vibration and impact, also providing some heat dissipation for higher-temperature media. It is used to protect the pressure gauge and minimize the temperature-related errors.

3. The damping screw at the pressure gauge joint hole of the pressure gauge bend part reduces the flow area to achieve a throttling and buffering effect, primarily benefiting the pressure pulse of the medium.
