Regarding the installation of sampling valves for scale-prone pipelines
Thread Content
I would like to ask everyone: how should the size of the sampling valve for pipes that are prone to scaling be determined? If the sample size is too small, it’s easy to get clogged; if it’s too large, it hinders sampling. I’m curious how you address this issue in your design
For sampling valves on pipes prone to scaling, it is generally necessary to select an appropriate size based on the specific process conditions and the characteristics of the pipes. Here are some common selection principles: 1. Based on the pipeline flow rate: High flow rates can cause the sampling valve to clog easily; therefore, a larger sampling valve can be chosen to reduce the flow rate and ensure more stable sampling. 2. Based on the pipe diameter: Generally, the diameter of the sampling valve should be kept between 10% and 25% of the pipe diameter. If the diameter of the sampling valve is too small, it will result in increased resistance and flow velocity, making blockages more likely to occur. 3. Based on pressure loss: Choosing a larger diameter for the sampling valve can reduce pressure loss and improve the sampling efficiency. 4. Based on particulate matter: If there is a large amount of particulate matter in the pipeline, it is recommended to use a sampling valve with an automatic cleaning function to prevent blockages. In summary, selecting the size of a sampling valve requires taking various factors into consideration, including flow rate, pipe diameter, pressure loss, and particulate matter, and making decisions based on specific circumstances. It is best to have professional engineers conduct detailed calculations and analyses based on the actual conditions, to ensure the proper operation of the sampling valve. .
The answer is very comprehensive, thank you:handshake
