Petroleum and natural gas industries - Steel pipes for use as casing or tubing for wells
ISO 11960:2014 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 ISO 11960:2014. 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.
By agreement between the purchaser and manufacturer, ISO 11960:2014 can also be applied to other plain-end pipe sizes and wall thicknesses.
ISO 11960:2014 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 (IJ).
ISO 11960:2014 can also be applied to tubulars with connections not covered by ISO/API standards.
The four groups of products to which ISO 11960:2014 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.
