本文件规定了为确定套管和油管接头的磨损趋势、密封性能和结构完整性而进行的试验。“套管”和“油管”适用于服务应用，而不适用于管道直径。 本文件涵盖了最常见井况下的连接测试。并不是所有可能的服务场景都包括在内。例如，不考虑腐蚀性液体的存在，这可能会影响接头的使用性能。 本文件补充了API RP 5C5:2017，其要求适用于本文件规定的例外情况。

This document specifies tests to perform in order to determine the galling tendency, sealing performance and structural integrity of casing and tubing connections. "Casing" and "tubing" apply to the service application and not to the diameter of the pipe. This document covers the testing of connections for the most commonly encountered well conditions. Not all possible service scenarios are included. For example, the presence of a corrosive fluid, which can influence the service performance of a connection, is not considered. This document supplements API RP 5C5:2017, the requirements of which are applicable with the exceptions specified in this document.
