Dear teachers, 1. 68% sulfuric acid, temperature 100 degrees, what material is used for the pipe? The sampler I bought is 316L. Can it resist corrosion? The entire system is now enameled and the sampler is 316L. 2. Mix acid of 68% sulfuric acid and 65% nitric acid at a temperature of 100 degrees. What material is used for the pipe? The sampler I bought is 316L. Can it resist corrosion? The entire system is now enameled and the sampler is 316L.

I’m sure 316L won’t work, nor will any general stainless steel. It should only be alloy steel, and I don’t know about the others.

What manual does your chart come from?

Use CS-Lined PTFE.

Hello, landlord! You definitely can’t use stainless steel for media like this! We have PTFE lined samplers! Satisfy your industrial control!

Acid-resistant ceramics or fluoroplastics are acceptable
