|This Standard specifies the technical delivery conditions for
steel pipes (casing, tubing and pup joints), coupling stock,
coupling material and accessory material and establishes
requirements for three Product Specification Levels (PSL-1, PSL-2,
PSL-3). The requirements for PSL-1 are the basis of this Standard.
The requirements that define different levels of standard technical
requirements for PSL-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 Standard, the sizes, masses and wall
thicknesses as well as grades and applicable endfinishes are listed
in Tables C.1 and C.2 and Tables E.1 and E.2.
By agreement between the purchaser and manufacturer, this
Standard can also be applied to other plain-end pipe sizes and wall
This 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 Standard specifies the technical
delivery conditions for couplings and thread protection.
Supplementary requirements that can optionally be agreed for
enhanced leak resistance connections (LC) are given in A.11
This Standard can also be applied to tubulars with connections
not covered by API standards.
The four groups of products to which this Standard is applicable
include the following grades 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.
Casing sizes larger than Label 1: 4-1/2 but smaller than Label
1: 10-3/4 can be specified by the purchaser 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 and E.28.
Supplementary requirements that can optionally be agreed between
purchaser and manufacturer for nondestructive examination, fully
machined coupling blanks, upset casing, electric-welded casing,
tubing and pup joints, impact testing, seal ring couplings, test
certificates, tensile testing and sulfide stress cracking testing
are given in Annex A.
This Standard is not applicable to threading requirements.
NOTE Dimensional requirements on threads and thread gauges,
stipulations on gauging practice, gauge specifications, as well as
instruments and methods for inspection of threads are given in API
