本标准涵盖螺栓法兰接头组件（BFJA），适用于带有环形垫圈的压力边界法兰接头，环形垫圈完全位于螺栓孔所包围的圆内，且在该圆外无接触。1本标准的原则可选择性地应用于其他接头几何结构。通过选择适合特定服务或需求的特征，本标准可用于制定适用于工业中通常遇到的各种尺寸和服务条件的有效接头装配程序。 本标准的用户[见第2（b）段]应注意，ASME PCC-1中包含的内容是通用开发的，不一定适用于所有应用。在某些情况下提供了预防性考虑，但不应视为包罗万象。应使用合理的工程判断和实践来确定特定方法或方法的一部分对特定应用的适用性。每个接头装配程序应由合格人员进行适当审查。 虽然本标准涵盖了ASME压力技术规范和标准范围内的接头组件，但也可用于根据其他规范和标准建造的设备。本标准还提供了对不具备密封性能的BFJA进行故障排除的指南（见非强制性附录P）。

This Standard covering bolted flange joint assemblies (BFJAs) applies to pressure-boundary flange joints with ring-type gaskets that are entirely within the circle enclosed by the bolt holes and with no contact outside this circle.1 The principles of this Standard may be selectively applied to other joint geometries. By selecting those features suitable to the specific service or need, this Standard may be used to develop effective joint assembly procedures for the broad range of sizes and service conditions normally encountered in industry.Users [see para. 2(b)] of this Standard are cautioned that the content contained in ASME PCC-1 has been developed generically and may not necessarily be suitable for all applications. Precautionary considerations are provided in some cases but should not be considered as all-inclusive. Sound engineering judgment and practices should be used to determine the applicability of a specific method or part of a method to a specific application. Each joint assembly procedure should be subject to an appropriate review by qualified personnel. While this Standard covers joint assembly within the scope of ASME Pressure Technology Codes and Standards, it may be used on equipment constructed in accordance with other codes and standards.Guidance on troubleshooting BFJAs not providing leaktight performance is also provided in this Standard (see Nonmandatory Appendix P).
