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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
