This standard replaces GB/T 9253.2-1999 "oil and gas industry casing, tubing and pipe thread processing, measurement and inspection Test ". Compared with GB/T 9253.2-1999, the main technical changes are as follows. --- Added Appendix C "Supplementary Requirements SR22"; --- Added "SI sheet"; --- Added "SI drawing"; --- Modify the external thread chamfer (from 65 ° to 60 °). Please note that some of this document may be patentable. The issuing agencies of this document do not bear the responsibility of identifying these patents. This standard by the National Standardization Technical Committee of Oil and Gas (SAC/TC355) centralized. This standard was drafted by China Petroleum Pipeline Engineering Research Institute. The main drafters of this standard. Yang Li, Fang Wei, Fung Chun, Wei respect justice. This standard replaces the standards previously issued as. --- GB/T 9253.2 ~ GB/T 9253.7-1988; --- GB/T 9253.2-1999. Oil and gas industrial casing, tubing and pipelines Thread machining, measurement and inspection1 ScopeThis standard specifies the API thread pipe, round thread casing, round thread tubing, partial trapezoidal thread casing, straight casing connection thread (Jane Called API threads) and gauge dimensions and marking requirements as well as instruments and methods for inspecting API threads and gauges. This standard applies to oil and gas industry with casing, tubing and pipe thread processing, measurement and inspection.2 Normative referencesThe following documents for the application of this document is essential.
