Origins and evolution, International Organization for Standardization. Features of size (FoSs) in reality always have actual sizes and forms that differ from their theoretical size and form; the purpose of tolerancing is to define whether the difference is acceptable or not. (Not to be confused with annotating strait pipe as "NPS", which should instead be annotated NPSM, NPSL, or NPSH, 1. KSI (or ksi), also abbreviated KPSI or kpsi, is a common non-SI measurement scale for ultimate tensile strength, that is, the number of units of tensile force that a material can endure per unit of cross-sectional area before breaking. P&ID symbols are used to represent components in a system. Flow elements represent functional pieces of equipment that help keep the plant processes moving in a designated direction. In the United States, the majority of these terms follow Norms ANSI or ASA. Defines centre-to-centre distance of two features, such as two holes. Crude oil stored in the storage tanks of the FPSO is offloaded onto shuttle tankers to go to market or for further refining onshore. This abbreviation is used in a machine shop when recording nonconformances. Like most such characteristics, its presence increases the price of the part, because it raises the costs of manufacturing and quality assurance.

When only certain companies are approved by the CDA to manufacture the product (that is, to make what the drawing depicts/defines), they are called by names such as "approved supplier", "approved product supplier", "approved vendor", or "approved product vendor". CR is for critical features whose performance truly requires near-perfect geometry. See also. The threshold of defectiveness that is allowable in a group of parts. Standards established by the U.S. military and widely used in the aerospace manufacturing (military and civil) and other defense industries. With the dissemination of software usage (CAD, CAM, PDMSs), revision control is often better handled nowadays, in competent hands at least. 2. Engineering drawings and material or process specifications are often revised; the usual revision control convention is to label the versions A, B, C, D, etc. On a technical drawing a dimension or note that is given only for reference and therefore is not intended to be used as a part acceptance criterion (although it may be used as an aid to production or inspection). For example, a chamfer may be called out as 12 X 45, When a dimension is used in multiple places either of these prefixes can be added to the dimension to define how many times this dimension is used. Overlaps a lot in concept with a parts list (PL or P/L). Thus material condition (, Floating Production Storage and Offloading, An FPSO is a floating production system that receives fluids (crude oil, water and a host of other things) from a subsea reservoir through risers, which then separate fluids into crude oil, natural gas, water and impurities within the topsides production facilities on board.

Houston, TX 77094 . This same spirit is behind the shift in military standards from writing requirements about methods to writing them instead about performance, with the method to reach that goal being up to the ingenuity of the designer. A form of heat treatment in which the metal is first hardened and then tempered. It is trivial to say that no one wants any error, and that everyone wants uniform perfection; but in the real world, it almost never happens. While you may understand the basic terms such as KG and CM, it becomes more difficult when you come across terms such as CYL and EQUI SP. The symbols on the drawings show how components like resistors, capacitors, inductors, switches, lamps, acoustic devices, measuring devices and other electrical and electronic components are connected together. For example, "4 REQD" written next to a fastener means that four of those fasteners are required for the assembly.
