Correct material selection
Correct material selection
(OP)
We are working with Sulphuric Acid 0-98% (0-100 degrees celcius) and Hydrochloric Acid (Ambient temperature +- 40 degrees celcius). I am having trouble allocating a proper Polymere (Plastic pipes, valves and tanks)to handle these products. We have now been looking at different supplier acid resistance charts and to be honoust, I am now getting confused. Some indicates that PVDF can do the job while other say PP. I am looking for a handbook that have the correct Acid and Polymere comparitive matrix charts. I bought a book "Material Selection Handbook" but that one is not really helping with the comparitive selection process. I understand that Hastelloy B will be appropriate but want to look at the correct polymere type material.

If you're using these acids at more modest temperatures (i.e. 40- 60 C tops), look at what they're shipped in: HDPE drums. If you're not designing for 20+ year durability and your application is of modest size, there's much you can get away with.
Chemline has one of the best chemical resistance charts I've found for thermoplastics (www.chemline.com), indicating both temperature and concentration for most potential corrodents.
