Storage and transportation of concentrated phosphoric acid

This post was last edited by Clauspolunit on 2015-12-11 at 12:58. Our company plans to use 85% concentrated phosphoric acid as an additive for steel-making refractory bricks. Due to a lack of experience in this area, we are hesitant to make decisions regarding the materials to be used for storage and transportation equipment. Any experts with experience in this field are requested to offer their help.
I’ve never seen concentrated phosphoric acid before; in my opinion, it is corrosive to metal containers, so it should be transported in glass bottles or through plastic pipes
For this type of corrosive medium, at temperatures and pressures that are not high, fluorinated-lined pipes and equipment are the preferred choice; they can handle changes in concentration without issue, and their cost is low. Appropriate metal materials, on the other hand, are more expensive.
Equipment and fittings made of tetrafluoro material have no issues in terms of corrosion resistance. However, I’m not sure what the structure of your equipment is; if it’s convenient for you, please send the equipment drawings to my email address: 77390271@qq.com
