1.1 This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing andpup joints), coupling stock, coupling material and accessory material and establishes requirements for threeProduct Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of thisInternational Standard. The requirements that define different levels of standard technical requirements forPSL-2 and PSL-3, for all Grades except H-40, L-80 9Cr and C110, are contained in Annex H.For pipes covered by this International Standard, the sizes, masses and wall thicknesses as well as gradesand applicable end-finishes are listed in Tables C.1 and C.2 and Tables E.1 and E.2.By agreement between the purchaser and manufacturer, this International Standard can also be applied toother 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 (SC);—long round thread casing (LC);—buttress thread casing (BC);—non-upset tubing (NU);—external upset tubing (EU);—integral tubing connections (IJ).For such connections, this International Standard specifies the technical delivery conditions for couplings andthread protection. Supplementary requirements that can optionally be agreed for enhanced leak resistanceconnections (LC) are given in A.11 SR22.This International Standard can also be applied to tubulars with connections not covered by ISO/API standards.1.2 The four groups of products to which this International Standard is applicable include the followinggrades of pipe:—Group 1: All casing and tubing in Grades H, J, K, N and R;—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.1.3 Casing sizes larger than Label 1: 4-1/2 but smaller than Label 1: 10-3/4 can be specified by thepurchaser to be used in tubing service, see Tables C.1, C.23, C.27 and C.28 or Tables E.1, E.23, E.27 andE.28.1.4 Supplementary requirements that can optionally be agreed between purchaser and manufacturer fornon-destructive examination, fully machined coupling blanks, upset casing, electric-welded casing, tubing andpup joints, impact testing, seal ring couplings, test certificates, tensile testing and sulfide stress crackingtesting are given in Annex A.1.5 This International Standard is not applicable to threading requirements.NOTE Dimensional requirements on threads and thread gauges, stipulations on gauging practice, gaugespecifications, as well as instruments and methods for inspection of threads are given in API Spec 5B.
