At what thickness reduction of the reactor vessel wall is it necessary to replace it? What are the criteria for scrapping reaction vessels? Especially for enamel-coated reaction vessels, when in use, whether it’s the stirring shaft, the large lid, or the vessel body itself, if there are any areas where the enamel is damaged, even if it’s just a small area, they insist on replacing the entire component. Is this reasonable? No waste?
Determined by the equipment based on the calculation results of temperature and pressure conditions.
On the stirring shaft, the large pot lid, and the pot body, if there are cracks in the porcelain, as long as they cover only a small area, they can be repaired.
On the stirring shaft, the large pot lid, and the pot body, if there are cracks in the ceramic material, as long as the affected area is small, it can be repaired.
How to repair it? Is it necessary to send it back to the factory? Please provide the diagrams of the construction equipment along with instructions
Small ones can be repaired by oneself; large ones need to be sent back to the factory
It is generally determined by the operating conditions, but if pressure issues are detected, corrective actions must be taken. Many companies calculate it on their own and make repairs before continuing to use the equipment.
The wall thinning amount of the container is specified by the designed corrosion margin. Generally, it is 1.6 mm for carbon steel and 0.8 mm for stainless steel. Reactor vessels with enamel linings – the lining can be repaired, but the repair materials are very expensive (gold pins are used).
Check the operating conditions! Minor damage to enamel reactors can be repaired! And some of them have been in use for several years with no problems! If it really has to be sent back to the factory for repair, it’s better to get a new one! The cost of one repair should be 60% of the price of a new kettle
Using enamel leads to severe corrosion; the substrate will corrode rapidly once the enamel cracks
