Troubleshooting in the design of pressure vessels with negative pressure under design pressure.
When designing pressure vessels, it is essential to consider negative pressure in the design!
We would like to introduce our stainless steel tank and filter housing VA and VE case studies. When there is a negative pressure in the design pressure of pressure vessels such as stainless steel pressure vessels, it is stipulated that the test pressure is determined by the differential pressure between the negative pressure area and the maximum operating pressure. Therefore, it is essential to consider negative pressure during the design of pressure vessels. [Key Points of the Case Studies] - The test pressure for pressure vessels subjected to negative pressure differs from that of pressure vessels not subjected to negative pressure. - When negative pressure is present, it is necessary to determine the test pressure based on the differential pressure between the negative pressure area and the maximum operating pressure. Failing to perform this calculation may result in failure during testing after the pressure vessel is completed, so caution is required. *For more details, please refer to the PDF document or feel free to contact us.
