API 5CT-2006 pdf download.Specification for Casing and Tubing .
1 Scope 1 .I This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain-end casing liners and pup joints), coupling stock and accessories and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of this International Standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3, for all Grades except H-40 and L-80 9Cr, are contained in Annex H. For pipes covered by this International Standard, the sizes, masses and wall thicknesses as well as grades and applicable end-finishes are listed in Tables C.l to C.3 and Tables E.l to E.3. By agreement between the purchaser and manufacturer, this International Standard can also be applied to other plain-end pipe sizes and wall thicknesses. This International Standard is applicable to the following connections in accordance with API Spec 5B: short round thread casing (STC); long round thread casing (LC); buttress thread casing (BC); extreme-line casing (XC); non-upset tubing (NU); external upset tubing (EU); integral joint tubing (IJ). I For such connections, this International Standard specifies the technical delivery conditions for couplings and thread protection. Supplementary requirements that may optionally be agreed for enhanced leak resistance connections are given in Annex A. 1 1 (SR22). This International Standard can also be applied to tubulars with connections not covered by ISO/API standards. 1.2 grades of pipe: The four groups of products to which this International Standard is applicable include the following – Group 1: All casing and tubing in Grades H, J, K and N; – Group 2: All casing and tubing in Grades C, L, M and T; – Group 3: All casing and tubing in Grade P; – Group 4: All casing in Grade Q.
