The test requirements of the mechanical seal API682 standard:

In the API682 standard, performance design and demonstrative experiments are indispensable. There are three specific tests, namely: quality appraisal test, hydrostatic test and overall test. For details, see Table 7-3. Mechanical seal manufacturer

Table 7-3 Introduction to the three test requirements

Note: ① In addition to the quality appraisal test described in the table, the quality qualification test for inhibiting sealing and double-end gas film sealing is added.

② The double-end air film seal is designed for the working conditions of being filled with high-level cold barrier gas, and the pressure of the blocking gas is higher than the medium pressure of the sealed cavity. In actual operating conditions, the supply of gas may be interrupted. This may affect the performance of the seal. The quality inspection of this type of seal not only includes the test of the fluid seal under the same conditions as described in the flush operation, but also includes multiple opening and closing tests, as well as the test of the pressure and temperature changes of the process fluid.' After completing the test, the seal has withstood a thousand disturbances that may be caused by blocking the supply of gas. 　　1107.html,
