When specific model of manufacture of the element is not to be specified, then the material can be identified by ANSI Standards.

The American Iron and Steel Institute (AISI) : These specify the material by its Chemical and Physical properties.

API 1104 - Standard for Welding Pipeline and Facilities.

API 607 - Fire Test for Soft Seated Ball Valves.

API 605 - Large Diameter Carbon Steel Flanges.

API 604 - Ductile Iron Gate Valves - Flanged Ends.

API 602 - Compact Design Carbon Steel Gate Valves.

API 601 - Metallic Gaskets for Refinery Piping.

API 593 - Ductile Iron Plug Valves - Flanged Ends.

API 6F - Recommended Practice for Fire Test for valves.

API 6D - Pipe Line Valves, End Closures, Connectors and Swivels.

The American Petroleum Institute (API) : The Standards referred by Piping Engineers are: The American Standards referred by Piping Engineers are: Most of these Standards are adapted by ASME (American Society for Mechanical Engineers). The Material Standards are covered under ASTM (American Society for Testing and Materials) and Dimension Standards under ANSI (American National Standards Institute). In India, other than American Standards, British and Indian Standards are also used for design and selection of Piping Systems.ĪMERICAN STANDARDS: Not all American Standards are issued directly by American National Standards Institute. On global basis, American National Standards are the most widely used and compliance with those requirements are accepted world over. These cover various engineering methods which are considered good practices, without specific recommendations or requirements.Ĭodes and Standards, besides being regulations, might also be considered as Design Aids since they provide guidance from experts.Įach country has its own Codes and Standards. RECOMMENDED PRACTICES: Documents prepared by professional group or committee indicating Good Engineering Practices but which are optional.Ĭompanies also develop Guides in order to have consistency in the documentation. STANDARDS: Documents prepared by a Professional group or Committee which are believed to be good and proper Engineering Practices and which contain mandatory requirement. The main objective is to have Standardization and Safety.ĬODE: A group of general rules or systematic procedures for Design, Fabrication, Installation and Inspection methods prepared in such a manner that Code can be adopted by legal jurisdiction and made into a law. Standards are published by Professional Societies, Committees and Trade Organizations. Standardization reduces cost, confusion and inconvenience. For Piping Systems, proper selection of Material of Construction along with Specifications, and Adherence to Codes and Standards is essential.
