Dear saxon,

Thanks for your reply.
Temp is 40°C.
Suction is from road tanker(open to atomosphere), it is to be transferred to storage tank of about 10 Mts Height.

Thanks.

Polymer-lined equipment will give the best combination of corrosion resistance and value for money at this concentration and temperature. PTFE/ETFE/PFA/PVDF will definitely stand up to the acid. PP is a cheaper choice which should also be resistant. I personally wouldn't use PVC or CPVC for this concentration.

Thanks for the info moltenmetal.

You can use 3.3 borosilicate glass pipe line for piping .But you should check the pressure withstanding.This can work for 70% sulfuric acid for even higher temperatures.
You should discuss the same with industrial glass manufacturer like QVF.
