Reasons and treatment suggestions for cracking of side line waste liquid storage tank head
Stress corrosion cracking accounts for a significant proportion of cracking cases in austenitic stainless steel containers.Taking the tetrahydrofuran side line waste liquid storage tank in the PBT device as an example,this ar-ticle deeply analyzes the causes of cracks in the stainless steel container from multiple perspectives such as materi-al,temperature,medium,and welding.The study proposes that steady-state austenitic stainless steel materials should be given priority in the manufacturing process of the head,and the processing technology should be strictly controlled.At the same time,mechanical hammering methods should be appropriately used to eliminate residual stresses and other preventive measures to prevent stress corrosion cracking of austenitic stainless steel containers.Through these measures,the corrosion resistance and reliability of austenitic stainless steel containers can be effec-tively improved,thereby reducing the risk of stress corrosion cracking and ensuring the long-term stable operation of the containers.
