Inspection of finished sulfuric acid tanks
Thread Content
After being manufactured, the finished sulfuric acid tanks need to be filled with water for leak testing and flaw detection. What is the best method for flaw detection? Should this task be carried out by the manufacturer or by the user? How are the costs associated with flaw detection calculated?
A airtightness test should be conducted without using water for leak testing; using water will leave residues that can corrode the tank. Additionally, flaw detection is necessary, and it must be carried out by a qualified agency, as it involves pressurized containers. If testing is done by an unqualified entity, the safety supervision authorities will not recognize its results. **Certificates** require these test results as evidence
Inspection is carried out by the manufacturer, and the costs associated with inspection are included in the manufacturing costs. The common methods used are ultrasound or X-rays. Water testing for leaks is performed after all other inspections have been completed.
