Are there any measures to prevent scaling of materials in pipelines?

Thread Content

We produce an organic chemical product, and the material tends to precipitate and form scale on the pipe walls; this can lead to the pipes becoming blocked. Do you have any good solutions?

First, you need to figure out the conditions under which scaling occurs and address them accordingly. The most direct way in which scaling forms on the pipe walls is when substances first adhere to those walls; then a small amount of scale forms, and subsequently, this scale causes more substances to adhere, thereby accelerating the scaling process! So the simplest solution is to replace the mirror-like tube material, thereby preventing the medium from adhering to the tube walls. The effectiveness of this solution depends on the smoothness of the inner surface of the tube; the higher the smoothness, the better the result! Valves work too!

Poor liquidity? See if a heat tracing jacket is needed

Thank you. I haven’t worked with mirror finish tubing before; is it easy to purchase?

It’s not due to poor liquidity; rather, there is material adhering to the pipe walls, and this accumulation keeps increasing. It’s also not caused by temperature – the material is in suspension form

The surface finish of RA0.4 domestically is satisfactory; values below RA0.2 typically require ultra-high purity gases and electron polishing.

For Ra0.4 and above, mechanical polishing can achieve the desired result. Based on the poster’s description, it seems to be just a suspension; likely a slurry. 1. The pipe layout should use a step-down or step-up configuration. 2. Elbows should be of large radius (3D, 5D, 10D). 3. This section of pipe, along with the valves, should be replaced with polished pipes and polished valves. If you have no budget concerns, go straight for the best option; if you want to save money, replace the components gradually following the 1-2-3 sequence. Step 3 can be further divided into mechanical polishing and electrolytic polishing – if mechanical polishing doesn’t work, then electrolytic polishing of the pipes is the only option left.

You’ve thought of everything; thank you!

It’s quite easy to purchase it as long as there is a demand. The pipes used in the pharmaceutical and food industries are all mirror-polished, and it is best to choose valves with a straight-through design for optimal performance.

Hello, our company specializes in scale prevention and removal. Our microwave scale prevention equipment can effectively prevent scaling caused by many types of inorganic salts. I’m not sure about the situation on your end; could we communicate via WeChat? TigerPeng2014
