Pipeline material for sulfuric acid
Pipeline material for sulfuric acid
(OP)
Dear all engineers,
Do you have any ideas about what material can be used for strong sulfuric acid lines (99% w/w).
Can we use simple carbon steel, or do we need stainless steel ?
Any comments would be very helpful
Thank you.
Regards.

Huh? I work in the semiconductor world, and we see PVC all over the place for Waste drains and chemical supply.
I design aqueducts in a parallel universe.

At moderate temp (30C) iron and steel will not handle 99% acid without noticeable corrosion.
High Si alloys (both cast irons and stainless grades) work well.
304 will work if there are never any Cl.
