API 5LC 2020 pdf download.CRA Line Pipe.
1 Scope Coverage 1.1 This specification covers seamless, centrifugal cast, and welded alloy line pipe with improved corrosion resistant properties. The purpose of this specification is to provide standards for pipe with improved corrosion resistance suitable for use in conveying gas, water, and oil in both the oil and natural gas industries. The size designations are nominal pipe sizes (NPS). In the text paragraphs herein, where pipe size limits (or size ranges) are given, these are outside diameter sizes except where stated to be nominal. These outside diameter size limits and ranges apply also to the corresponding nominal sizes. The primary product is beveled pipe. If plain-end square cut or other special end preparation is desired, this shall be subject to agreement between the purchaser and manufacturer. Included are NPS 1 in. through 42 in. Grades covered by this specification are LC30-1812, LC52-1200, LC65-2205, LC65-2506, LC30-2242, and LC80-2507 1 . Application of the API Monogram 1.2 If product is manufactured at a facility licensed by API and it is intended to be supplied bearing the API Monogram, the requirements of Annex A apply. 2 Normative References For dated references, only the edition cited applies.

3 Terms, Definitions, and Abbreviations Terms and Definitions 3.1 For the purposes of this specification the following definitions apply. 3.1.1 heat The metal produced by a single cycle of a batch melting process. 3.1.2 heat analysis The chemical analysis representative of a heat as reported by the producer. 3.1.3 inspection The process of measuring, examining, testing, gaging, or otherwise comparing the unit of product with the applicable requirements. 3.1.4 lot A definite quantity of product manufactured under conditions that are considered uniform, for the attribute to be inspected. 3.1.5 lot size The number of units of product in a lot. 3.1.6 manufacturer Refers to the firm, company, or corporation responsible for marking the product to warrant that the product conforms to the specification. NOTE The manufacturer may be either a pipe mill or a processor, as applicable. This manufacturer is responsible for compliance with all of the applicable provisions of the specification. 3.1.7 pipe mill A firm, company, or corporation that operates pipe-making facilities.
4 General Information Metric Units 4.1 Metric units in this specification are shown in parentheses in the text and in many tables. Outside diameters air wall thicknesses are converted from inch dimensions. The converted diameters are rounded to the nearest 0.1 mm for diameters less than 18 in. and to the nearest 1.0 mm for diameters 18 in. and larger. Wall thicknesses are rounded to the nearest 0.1 mm. Metric inside diameters are calculated from the metric outside diameters and wall thicknesses and rounded to the nearest 0.1 mm. Metric plain-end weights are included from the metric outside diameters and wall thicknesses using the equations in 10.1 and rounded to the nearest 0.01 kg/m (0.01 lb/ft). Metric hydrostatic pressures are calculated from metric outside diameters and wall thicknesses and metric fiber stresses shown in Section 9. The factors used where conversions are appropriate are as follows: 1 inch (in.) = 25.4 millimeters (mm) exactly 1 square inch (in. 2 ) = 645.16 square millimeters (mm 2 ) exactly 1 foot (ft) = 0.3048 meters (m) exactly 1 pound (lb) = 0.45359 kilograms (kg) 1 pound per foot (lb/ft) = 1.4882 kilograms per meter (kg/m) 1 pound per square inch (psi) = 6.895 kilopascals (kPa) for pressure = 0.006895 megapascals (MPa) for stress 1 foot-pound (ft-lb) = 1.3558 Joules (J) for impact energy
