标准范围

ISO 11960:2010规定了钢管（套管、油管和短节）、联轴器库存、联轴器材料和附件材料的交货技术条件，并确定了三个产品规范等级（PSL-1、PSL-2、PSL-3）的要求。PSL-1的要求是ISO 11960:2010的基础。附录H中规定了除H-40、L-80 9Cr和C110外的所有等级的PSL-2和PSL-3标准技术要求的不同级别。对于ISO 11960:2010涵盖的管道，列出了尺寸、质量、壁厚、等级和适用的端部饰面。根据买方和制造商之间的协议，ISO 11960:2010也可适用于其他平端管尺寸和壁厚。ISO 11960:根据API Spec 5B，2010适用于以下连接:短圆螺纹套管（SC）、长圆螺纹套管（LC）、扶壁螺纹套管（BC）、非镦粗管（NU）、外部镦粗管（EU）和整体管连接（IJ）。对于此类连接，ISO 11960:2010规定了联轴器和螺纹保护的技术交付条件。给出了增强型抗泄漏连接（LC）的补充要求。ISO 11960:2010也适用于ISO/API标准未涵盖的连接管件。ISO 11960:2010适用的四组产品包括以下等级的管道:第1组，包括H、J、K、N和R级的所有套管和油管；第2组，包括C、L、M和T级的所有套管和油管；第3组，包括所有P级套管和油管；第4组，包括所有Q级套管。买方可指定大于标签1:4-1/2但小于标签1:10-3/4的套管尺寸，以用于油管服务。给出了买方和制造商就无损检测、全机加工联轴器毛坯、镦粗套管、电焊套管、油管和短节、冲击试验、密封圈联轴器、试验证书、拉伸试验和硫化物应力开裂试验达成的补充要求。ISO 11960:2010不适用于螺纹要求。API Spec 5B中给出了螺纹和螺纹量规的尺寸要求、计量实践规定、量规规范以及螺纹检验仪器和方法。

ISO 11960:2010 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 11960:2010. 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.For pipes covered by ISO 11960:2010, the sizes, masses and wall thicknesses as well as grades and applicable end-finishes are listed.By agreement between the purchaser and manufacturer, ISO 11960:2010 can also be applied to other plain-end pipe sizes and wall thicknesses.ISO 11960:2010 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) and integral tubing connections (IJ).For such connections, ISO 11960:2010 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.ISO 11960:2010 can also be applied to tubulars with connections not covered by ISO/API standards.The four groups of products to which ISO 11960:2010 is applicable include the following grades of pipe: group 1, including all casing and tubing in grades H, J, K, N and R; group 2, including all casing and tubing in grades C, L, M and T; group 3, including all casing and tubing in grade P; and group 4, including 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 for use in tubing service.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, test certificates, tensile testing and sulfide stress cracking testing are given.ISO 11960:2010 is not applicable to threading requirements. 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.
