High temperature pipeline pressure gauge
Thread Content
Can the temperature be lowered by installing a pressure gauge on a pipeline with a condensing capillary tube at 500°C (the highest temperature may reach 600°C)? Whether other cooling (insulation) measures are required. The medium is high-purity water. This post was last edited by uuzq on 2009-2-9 09:38 ]
The effect will be better if you add heat sinks and condensation rings.
Just install a condensation ring. Its official name is a buffer tube. It mainly reduces vibration and impact. It can also play a certain role in heat dissipation for higher temperature media to protect the pressure gauge and reduce the error caused by the temperature of the pressure gauge. The damping screw at the orifice of some pressure gauge joints has a throttling and buffering effect by reducing the flow area. Mainly useful for medium pressure pulses.
In addition, the space is not large, but there are many pipes, and they are all media above 300°C. Will this affect the heat dissipation effect of the condensation ring? If a condensation ring is used, how long should it be?
Appropriate extension of the pressure pipe is also a measure
Furthermore, choose a high temperature resistant pressure gauge!
Under normal circumstances, installing a condensation bend can solve the problem. If the temperature still cannot drop, use a condensation bend with a heat sink.
At such a high temperature, it is best to take protective measures for the pressure gauge. The method is explained above.
It is recommended to add an isolation tank, which can not only isolate the medium, but also reduce the temperature. At the same time, choose a high-temperature resistant pressure gauge with a heat sink.
The following three methods can solve the problem of the landlord:: 1. Use condensation bend, length 500mm ； 2. Isolate with cross condensation tank ； 3. High temperature diaphragm pressure gauge can be used.
I feel that many people upstairs have never installed local pressure gauges on high-temperature and high-pressure pipelines! ? 1 There are two options for the pressure taking device: A. You can choose a pipe stop valve specially designed for mechanical engineering to take pressure. B. You can choose a professional welding valve with a sufficient pressure level for instrumentation. Of course, the material and welding technology must be excellent. 2. Install a condensation ring. This condensation ring is a standard condensation ring for professional instrumentation. The diameter can be 14 or 16 mm. As for the thick or thin skin tube, you can also choose according to the pressure and temperature. 3. Depending on whether there is vibration at the site, the meters and instrument tubes generally have to be fixed or restricted to prevent them from shaking too much. 4. It is best to choose a pressure gauge with a heat sink. In addition, it is best to choose a measuring range that is twice the long-term pressure of the process. It must not be used to 2/3. This can make the pressure gauge have a longer life and prevent the gauge from being damaged when starting and stopping the pressure.
Thank you for your enthusiastic help:handshake
I think first of all, your explanation is what medium you are measuring and the nature of the medium. If it is liquid and easy to condense, I think it is best not to use a condensation ring but to use an isolation tank.
