American Petroleum Institute API Specification

The wall thickness of the coil can be chosen by using any number of recognized codes and standards. In the United States, the most commonly recognized are American National Standard Institute (ANSI) B31.3 and B31.8, or American Petroleum Institute (API) Specification 12 K. Volume 1 has the tables for ANSI B31.3 and ANSI B31.8. Table. - -1... 

Solid Phases. The commonest weighting agent is barite, which, in its pure form, has a density of 4500 kg/m3. The American Petroleum Institute (API) specification (12) for the density of barite is that it must be at least 4200 kg/m3. Other API specifications are the soluble alkaline metal concentrations must not exceed 250 ppm and a maximum of only 3 wt% of the barite must have a particle size in excess of 75 pm with a maximum of 30 wt% having a particle size of less than 6 m. Other suspended weighting agents are calcium carbonate and iron oxide [hematite (12)], although iron oxide is not often used due to its abrasiveness.

Pipeline used for transportation of gas, oil or water utility distribution pipeline system ranging in sizes /8-42 in. o.d. inclusive. Fabricated to American Petroleum Institute (API) and American Water Works Association (AWWA) specifications. 

The design practices compiled in this volume were derived firom the literature of the American Society of Testing Materials (ASTM), the American Petroleum Institute (API), the ANSI Codes, a review of company specific literature including company design practices and general publications, and the author s personal notes compiled over the years as a consultant and practicing engineer, as well as an instructor to Venezuelan refinery and chemical plant operations. 

American Petroleum Institute (API), Spec 14A. Specification for Subsurface Safety Valve Equipment. Eighth Edition, API, Washington, D.C., 1994. 

Hydrometers are calibrated in density, specific gravity, and several arbitrary units such as degrees Baume (°Be), degrees American Petroleum Institute (°API), or °Brix. These units are used for specialized purposes in various industries. The relationship between the specific gravity (sp. gr.) of a liquid with a density less than water and these specialized units is given by the following equations ... 

Additional resources include the National Fire Protection Association (NFPA), the Society for Fire Protection Engineers (SFPE), Fire Suppression Systems Association (FSSA), and the American Petroleum Institute (API). Refer to the References section of this Guideline for specific resources. 

API Gravity A scale devised by the American Petroleum Institute (API) designating an oil s specific gravity or the ratio of the weight of oil to pure water. 

The American Petroleum Institute (API) maintains cooperation between U.S. government and industry on all petroleum-related issues of U.S. concern. The API provides process hazards and process safety seminars, but they are best known to some of us for their valuable publications. The API generates easy-to-read and easy-to-understand technical standards of design and fire protection. They also provide equipment inspection guides that are applicable in most plants. Specific information about their large number of standards can be obtained at their website. 

Example 4.27 Assessment of separation of a 15-component mixture in two columns The feed for the separation system is a 15-component mixture containing a pseudocomponent, which is specified with an American Petroleum Institute (API) degree of API = 48.6 or a specific gravity of 0.786 (see Figure 4.34). The first column operates at 13.26 atm with 30 stages. The feed enters at stage 8. The top product is rich in propane and the mixture of isobutene... 

American Petroleum Institute (API) has developed standards for testing downhole cements that are described in API recommended practice 10 [3]. In API specifications (API Spec. 10), if one assumes an ambient temperature of 80 °F (25°C), then the depth dependence of the downhole temperature is approximately given by... 

Fire-Rated Valves that handle flammable fluids may have additional safety-related requirements for minimal external leakage, minimal internal (downstream) leakage, and operability during and after a fire. Being fire-rated does not mean being totally impervious to fire, but a sample valve must meet particular specifications such as those of American Petroleum Institute (API) 607, Factory Mutual Research Corp. (FM) 7440, or the British Standard 5146 under a simulated fire test. Due to very high flame temperature, metal seating (either primary or as a backup to a bumed-out elastomer) is mandatory.
