Question

We have a vessel that we don't use for a long time , the inner diameter is 1200 mm, the minimum thickness is 10 mm, material is Q245R, double-sided welding butt joints , but not sure about the Nondestructive testing method. Now we want to use it with an internal pressure 1MPa, the work temperature is 200℃ and the allowable stress for Q245R at this temperature is 131 MPa , no corrosion problem. Please check whether we can use the vessel or not.
