API 610 is the API standard about centrifugal pumps and is primarily intended for use in the petroleum, natural gas and chemical industries. Although the 1st through 7th Editions of API 610 included specifications for mechanical seals, beginning with the 8th Edition, API 610 defers to API 682 for seal specifications.
The standards also include a test designed to protect against a phenomenon experienced by some gasoline engines known as Low-Speed Pre-Ignition (LSPI). [12] [13] 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 ...
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) [1] of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one liter in volume and having a maximum pressure more than 0.5 bar gauge.
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
ISO TC11 Standard 16528—Boilers and Pressure Vessels published, establishing performance requirements for the construction of boilers and pressure vessels and facilitating registration of BPV Codes to this standard 2007: High density polyethylene plastic pipe introduced into the Boiler and Pressure Vessel Code, Section III, Code Case N-755 2009
The European standard EN12186 (formerly the DIN G491) and more specific the EN14382 (formerly DIN 3381) has been used for the past decades in (mechanically) instrumented overpressure protection systems. These standards prescribe the requirements for the over-pressure protection systems, and their components, in gas plants.
The previous service categories such as API CC or CD are obsolete. API solved problems with API CI-4 by creating a separate API CI-4 PLUS category that contains some additional requirements – this marking is located in the lower portion of the API Service Symbol "Donut". API CK-4 and FA-4 have been introduced for 2017 model American engines. [24]
