Acidic materials are handled using pipes and valves
Thread Content
95% sulfuric acid and 31% hydrochloric acid are used in production. Additionally, vacuum pumping is required to recover the phosphorus trichloride liquid. What kind of pipes and valves would be suitable? I hope those with relevant experience can offer some advice. Also, please recommend some good manufacturers of pipes and valves that are durable – ideally, the best manufacturers available
Glass-lined steel is the first choice, followed by PTFE-lined steel, and then enamel-lined pipes
The PTFE lining is easy to use and comes at a reasonable price
Based on practical experience, steel-lined PTFE is recommended; it has a reasonable price and excellent corrosion resistance. Glass-lined steel requires high standards for installation, as the glass lining inside is fragile. There are many manufacturers of enamel pipes as well as those of glass-lined steel, so it’s sufficient to choose a larger manufacturer
It can be used; we have PTFE-lined pipe fittings for 95% sulfuric acid, and we have relevant experience in this area. Up to DN200, below 100 degrees, resistant to complete vacuum. Feel free to contact me if you need anything. Baum Fluoroplastics Shanghai Co., Ltd. – Baum is one of the world’s renowned manufacturers of corrosion-resistant fluoroplastic-lined pipes and fittings.
