API 598 Testing Requirement

The importance of API598 test sequence and requirements lies in ensuring the safety and reliability of valves under various working conditions. API598 standard specifies in detail the inspection, testing and other test requirements of valves, including valve pressure tests of elastic valve seats, non-metallic valve seats and metal valve seats. Through strict test sequence and requirements, the sealing performance of valves under different pressures and working conditions can be verified to ensure their stable operation under high pressure and low temperature environments.
