Tank corrosion, expert answer
Thread Content
The reflux tank at the top of the stabilizer in the coking unit – that is, the bottom of the liquefied gas tank – is suffering from severe corrosion. The designed wall thickness is 22 mm, but the actual minimum thickness measured is 11–12 mm. May I ask experts: can this tank still be used? Working pressure: 1.0 MPa
The parameters are incomplete; the diameter and material are unknown, and the structural format is also unclear, so it is not possible to provide an answer for now.
Personally, I feel it can no longer be used; it deviates greatly from the designed values, and the risk level is too high. It should be replaced at that speed.
Too many parameters are missing. Such as diameter, material unknown, structural form, medium, temperature, etc. It seems to be pretty dangerous. Polymer technology can be used in conjunction with reinforcement strips to strengthen the corroded areas of the tank.
