套管和油管连接的扭矩定位装配指南（第一版

[中文适用范围]： “本文件提供了 API 5B（动力转动）和 API 5C1（最佳扭矩）中的连接装配程序的替代连接装配程序。所规定的程序被称为“扭矩位置”，因为上扣扭矩和最终位置作为装配操作的验收标准。连接螺纹符合 API 5B。扭矩-位置装配参数已针对大多数 SC（短圆螺纹套管）@ LC（长圆螺纹套管）@ 开发。 BC（偏梯形螺纹套管）@ 和 EU（外加厚管）连接。扭矩定位是一种精密装配方法，依赖于成功实施的受控过程。当遵循定义的螺纹加工和装配程序时，最终装配连接的性能已优化。” [外文原描述]： This document provides alternative connection assembly procedures to those found in API 5B (power turns) and those found in API 5C1 (optimum torque). The procedures set forth are referred to as “torque-position” because the make-up torque and final position are used as acceptance criteria for the assembly operation. The connections are threaded in accordance with API 5B. The torque-position assembly parameters have been developed for most SC (short round thread casing), LC (long round thread casing), BC (buttress thread casing), and EU (external upset tubing) connections. Torque-position is a precision assembly method that relies on a controlled process for successful implementation. When defined threading and assembly procedures are followed, the performance of the resulting assembled connection is optimized.
