The pipes are usaged for Conveying gas,water,and oil in both the oil and natural industries

ISO 11960 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 5, Casing, tubing and drill pipe. Petroleum and natural gas industries —Steel pipes for use as casing and tubing for wells. This standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain-end



casing liners and pup joints), coupling stock and accessories 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 and L-80 9Cr, are contained in Annex H. For pipes covered by this standard, the sizes, masses and wall thicknesses as well as grades and applicable end-finishes are listed in Tables C.1 to C.3 and Tables E.1 to E.3. By agreement between the purchaser and manufacturer, this standard can also be applied to other plain-end pipe sizes and wall thicknesses.

This International Standard is applicable to the following connections in accordance with ISO 10422 or API Spec 5B: short round thread casing (STC); long round thread casing (LC); buttress thread casing (BC); extreme-line casing (XC); non-upset tubing (NU); external upset tubing (EU); integral joint tubing (IJ). For such connections, this International Standard specifies the technical delivery conditions for couplings and thread protection. For pipes covered by this International Standard, the sizes, masses, wall thicknesses, grades and applicable end finishes are defined. This International Standard may also be applied to tubulars with connections not covered by ISO/API standards.
