API Standard 682, titled "Pumps - Shaft Sealing Systems for Centrifugal and Rotary Pumps," is the American Petroleum Institute standard for end-face mechanical seals. [1] The purpose of API 682 is to assist in the selection and operation of end face mechanical seals in centrifugal pumps .
API also defines and drafts standards for measurement for manufactured products. Crude Oil Data Exchange (CODE) is the electronic business standard as of 1978. API RP 500 and RP 505 classify the locations for electrical equipment in hazardous areas. [14] [15] API has entered petroleum industry nomenclature in a number of areas: API gravity, a ...
Several dimensional and functional standards exist, such as API Standard 682 - Shaft Sealing Systems for Centrifugal and Rotary Pumps, which describes the configurations for used in Oil & Gas applications. Even though the scope of API 682 is somewhat limited, it may be extended to describe end-face mechanical seals in general.
The standard can be amended or qualified by national or regional standards bodies. [8] An ISO international standard can be published as a supplement to an API Standard via normative references and its technical content. API Standards can be readopted from ISO standards either as identical adoptions or with modifications. [8]
API Specification 421 requires a minimum length to width ratio of 5:1 and minimum depth-to-width ratio of 0.3:0.5. [4] Typically, the oil layer is skimmed off and subsequently re-processed or disposed of, and the bottom sediment layer is removed by a chain and flight scraper (or similar device) and a sludge pump.
A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
Sundyne Ansimag sealless magnetic drive pumps are non-metallic and fit ANSI standards. Sundyne HMD/Kontro sealless magnetic drive pumps are metallic with models in ISO, API-610, and API-685 standards. Sundyne manufactures multistage pumps with a single gearbox (HMP Line), horizontal BB series (Marelli), and V series vertical pumps (Marelli).
The American Petroleum Institute (API) oldest and most successful programs is in the development of API standards which started with its first standard in 1924. API maintains over 500 standards covering the oil and gas field. [2] The following is a partial list specific to welding:
