What is the latest edition of API 682?

API 682 is a key equipment standard for safe and reliable operation of mechanical seals and auxiliary piping systems. After six years of development, the 4th Edition now covers a multitude of seals designs and auxiliary piping systems. It can be referenced in the procurement of both new and retrofit equipment.

What is Non flashing hydrocarbon?

non-flashing hydrocarbon. non-flashing fluid. Liquid hydrocarbon or other fluid whose vapor pressure at any specified operating temperature is less than an absolute pressure of 0,1 MPa [1 bar] [14,7 psi], or a fluid that will not readily boil at ambient conditions. non-hydrocarbon service.

Is standard for mechanical seal?

Initial information about mechanical seals was originally provided in the API 610 pump standard. During the 90s, API 682 then developed into a separate, more comprehensive standard for mechanical seals and supply systems. A typical quality of the API 682 standard is that is permanently updated by practical people.

What are the requirements of API Standard 682?

After having defined the services, seal types, and seal arrangements, a series of flowcharts were created to help in selecting a seal type, special materials or design requirements, and supporting piping plans. API 682 seals were to have a high probability of three years of reliable service.

What is the purpose of API 682 in centrifugal pumps?

The purpose of API 682 is to assist in the selection and operation of end face mechanical seals in centrifugal pumps. It is based on the combined knowledge and experience of seal manufacturers, engineering companies and end users.

How is a containment seal reported in API 682?

Containment seal test results are to be reported using a form similar to API 682 Figure I.10 for the tests specified under clause I.4.5. This allows the containment seal to be considered as a “seal type” for purposes of transferring qualification.
