Can carbon steel be used for ethylene oxide spheres?
Thread Content
Most of the ethylene oxide spherical tanks we produce are made of stainless steel or composite materials; this time, a design institute suggested using carbon steel. Since ethylene oxide tends to undergo polymerization reactions, will rust removal and passivation of the inner wall be sufficient to solve the problem? Can carbon steel be used? Guys, what do you think?
According to the standards, Article 6.3 of GBT13098 specifies this clearly. Stainless steel should be given priority
Could you take a screenshot and show it to me so I can learn from it? Thank you!

This issue is similar to performing magnetic particle testing or penetrant testing; the standards state that magnetic particle testing should be preferred, but in one review it was said that using penetrant testing is not acceptable!
I can’t receive images, but I can tell you with certainty that our factory has just manufactured two ethylene oxide storage tanks, also known as EO spheres, using Q345R steel plates, with a capacity of 650 cubic meters each
