scope:

This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material.

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.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 to other plain-end pipe sizes and wall thicknesses.

API Spec 5L pipe may be ordered as casing in accordance with API RP 5C6.

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); ¾ non-upset tubing (NU);

- external upset tubing (EU);

- integral tubing (IJ).

For such connections, this International 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.9 SR22. This International Standard can also be applied to tubulars with connections not covered by ISO/API standards.

The products to which this International Standard is applicable include the following grades of pipe: H40, J55, K55, N80, L80, C90, R95, T95, P110, C110 and Q125. 1.3 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 non-destructive examination, fully machined coupling blanks, upset casing, electric-welded casing, tubing and pup joints, impact testing, seal ring couplings,enhanced leak resistance, tensile testing, sulfide stress cracking testing, yield strength, hardenability and hardness testing are given in Annex A.

This International 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 Spec 5B.
