Omfang

1.1 This International Standard specifies the techni­cal delivery conditions for steel pipes (casing, tubing and liners), pup-joints and connectors. This International Standard is applicable to the follow­ing connections in accordance with ISO 10422: — short, round-thread casing; long, round-thread casing; buttress-thread casing; — extreme-line casing; — non-upset tubing; — external-upset tubing; — integral-joint tubing. The applicable types of end finishing for each size are described in annex A (tables A.1 to A.3). For such connections, this International Standard specifies the technical delivery conditions for coup­lings and thread protection. Threading requirements are not considered in this In­ternational Standard. 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 ISO 10422. This International Standard may also be used for tubu­lars with connections not covered by ISO standards. 1.2 The products described by this International Standard are gathered in four groups as follows. — Group 1: all casing and tubing in grades H, J, K and N. — Group 2: all casing and tubing in restricted yield strength grades C, Land T. — Group 3: all seamless casing and tubing and 139, 70 mm and larger electric-welded (EW) casing in high strength grade P. — Group 4: all special service casing in grade 0. 1.3 Supplementary requirements, that may be agreed between interested parties, for non­destructive inspection, coupling blanks, upset casing, electric-welded casing, impact testing, seal-ring coup­lings and certificates are specified in annex B.
