(2010) TFL（通过流水线）系统的推荐做法（第二版；ISO 13628-3/ISO 13628-3 采用

[中文适用范围]： 本部分 ISO 13628 规定了 Through Flowline (TFL) 设备和系统的设计、制造和运行的要求及建议。 所提出的程序和要求适用于井下设备、海底树和油管挂以及流线和管线内设备的液压服务。 本部分主要涉及用于海上、海底应用的 TFL 系统，但也可能用于其他应用，如高偏斜井或水平钻井。 海底分离、增压、计量和井下泵不在本部分 ISO 13628 的范围内。 [外文原描述]： This document presents recommendations for designing, fabricating, and operating TFL (through flowline) equipment. Procedures and guidelines presented are for hydraulic servicing of downhole equipment, subsea tree and tubing hanger, and pipelines and equipment within the pipelines. This document primarily addresses TFL systems for offshore, subsea applications but it may also be used in other applications such as highly-deviated wells or horizontally-drilled wells. Subsea separation, boosting, metering and downhole pumps are outside the scope of this document.
