适用范围/摘要
ISO/5RP螺纹、油管和套管接头的专用螺纹和API推荐方法。本国际标准中概述的试验用于在实验室条件下评估螺纹化合物的关键性能、物理和化学特性。这些试验方法主要用于使用润滑基础脂配制的螺纹化合物。人们认识到，可能有一些材料用于螺纹连接的润滑和/或密封，这些试验方法不适用。 本RP不用于评估与旋转肩连接件一起使用的化合物。API RP 7A1中描述了此类评估。API RP 5A3的这个版本是建议国家采用ISO 13678的版本。
API RP 5A3 provides requirements, recommendations and methods for the manufacture, testing and selection of thread compounds for use on ISO/API round thread, buttress thread and proprietary casing, tubing and line pipe connections. The tests outlined within this International Standard are used to evaluate the critical performance properties, and physical and chemical characteristics of thread compounds under laboratory conditions.These test methods are primarily intended for thread compounds formulated with a lubricating base grease. It is recognized that there may be materials used for the lubrication and/or sealing of threaded connections for which these test methods are not applicable.This RP is not intended for the evaluation of compounds used with rotary shouldered connections. Such evaluation is described in API RP 7A1.This edition of API RP 5A3 is a proposed national adoption of ISO 13678.
