在油田应用中安全使用 2 英寸锤式由壬（第一版；包含勘误表：2014年2月

[中文适用范围]： 概述 本推荐做法 (RP) 提出了程序建议以及工程解决方案，以解决内螺纹 2 英寸图 402@ 内螺纹 2 英寸图 602@ 或内螺纹 2 英寸图 1002 锤由壬组件（子），带有 3.2 中所述的公 2 英寸图 1502 锤头由壬组件（蝶形螺母）。应实施本安置计划中描述的程序建议，以减少进一步的事件。该工程解决方案@可防止内螺纹2英寸图402@ 2英寸图602和/或2英寸图1002短节与2英寸图1502锤击由壬@的蝶形螺母配合，适用于制造新的由壬组件，因现场磨损造成未知因素，不宜应用于现有锤由壬组件的改造。 [外文原描述]： This recommended practice (RP) sets forth procedural recommendations as well as an engineering solution to the mismatching of a female 2-inch Figure 402, a female 2-inch Figure 602, or a female 2-inch Figure 1002 hammer union component (sub) with a male 2-inch Figure 1502 hammer union component (wing nut) as described in 3.2. The procedural recommendations described in this RP should be implemented to reduce further incidents. The engineering solution, which makes impossible the mating of female 2-inch Figure 402, 2-inch Figure 602 and/or 2-inch Figure 1002 subs with the wing nut of the 2-inch Figure 1502 hammer union, applies to the manufacture of new hammer union components and should not be applied in the modification of existing hammer union components due to unknown factors caused by field wear.
