Ratio of non-destructive testing for welds in ethyl acetate storage tanks at atmospheric pressure
Thread Content
Our company has an ethyl acetate storage tank with a capacity of 50 cubic meters, operating under normal temperature and pressure conditions. When constructing this tank, should the requirements specified in the \"Code for Welded Steel Pressure Vessels\" be followed? This code does not apply to tanks storing highly hazardous substances. Does that mean it has to be manufactured as a pressure vessel? In the case of manufacturing a pressure vessel, the defect detection rate for welds must be 100%. Do any of the experts have any other opinions?
Based on your description, your company’s storage tanks are for ethyl acetate at normal temperature and pressure. According to the requirements of \"Steel Welded Atmospheric Pressure Vessels,\" this standard does not apply to vessels storing highly hazardous materials. If your ethyl acetate is considered a highly hazardous medium, then in accordance with the requirements for manufacturing pressure vessels, the proportion of weld non-destructive testing must be 100%. However, I still recommend that you consult relevant professional organizations or process experts to ensure that the manufacturing and testing of your storage tanks meet the relevant requirements and to guarantee their safe operation. This is more beneficial to the interests and operational security of your company. .
Ethyl acetate is not a highly hazardous medium; it is merely a flammable medium
Yes, it was written wrong. It is a dichloromethane storage tank
