Auxiliary equipment of mechanical seal API682 standard:

The equipment of the sealing auxiliary system has received more attention in API682, and its requirements are extremely strict in some cases. For example, the seal flushing fluid cooler should be designed so that the process fluid and coolant can be completely discharged on both sides. The sealing fluid is on the side of the tube side, and the minimum diameter of the tube is 19mm.

For the multi-seal arrangement, the storage tank needs to be considered as a part of the piping system, and its design can meet the requirements of ANSIB 31.3. The specific requirements are: the storage tank is made of No. 40 316L stainless steel pipe, which has a 12.7mm (1/2in) cooling coil tube and the storage tank has a volume of at least 19L. With storage tanks, either an internal circulation device can be used for forced circulation, such as a pumping ring, or an external pressure source can be used. In Scheme 75, the storage tank not only collects the leakage, but also separates the gas-liquid mixed phase leakage, and guides the leakage into the recovery system along the pipeline; in addition, the storage tank can also be used to measure the state of the fluid and the storage tank. Pressure, and monitor the leakage of the inner seal by measuring the limulus. Mechanical seal fluid solution: API682 PLAN video
