A 60 CM crack appeared in the circumferential weld of the lower cylinder of the zinc oxide desulfurization tank; the designed temperature was 280 degrees, while the actual temperature was 286 degrees, with an operating pressure of 3.2 MPM.
The material of this zinc oxide desulfurization tank is 15CRMOR; the cylinder diameter is 60 millimeters, and the head diameter is 34 millimeters.
Judging from the situation described by the poster, it seems unrelated to temperature; the cracks in the welds appear to be due to manufacturing defects.
Is there a problem with the design temperature and operating temperature of your i? Additionally, there is an issue with the quality of the welding; welding this material is quite challenging. We have manufactured several units using this material, and the results have been good
