6.10.3 Bolting Recommendations. For flange joints, stud bolts with a nut at each end are recommended for all applications and especially for high temperature service.
6.11 Gaskets for Line Flanges
6.11.1 Ring Joint. Ring joint gasket dimensions shall conform to ASME B16.20.
6.11.2 Contact Width. For flanges having large or small tongue-and-groove faces, all gaskets, except solid flat metal gaskets, shall cover the bottom of the groove with minimum clearance. ISee para. 7.3(a) for tolerance applicable to groove.I Solid flat metal gaskets shall have contact width not greater than for Nonmandatory Appendix B, Group Ill gaskets.
6.11.3 Bearing Surface. For flanges with small male-and-female face, care must be taken to ensure that adequate bearing surface is provided for the gaskets. In particular, care is necessary when the joint is made on the end of the pipe as shown in Fig. 6 (Fig. 11-6 of Mandatory Appendix II).
6.12 Auxiliary Connections
6.12.1 General. Auxiliary connections or openings for flanged fittings are not required unless specified by the purchaser. Welding to attach auxiliary connections to flanged fittings shall be made by a qualified welder using a qualified weld procedure in accordance with Section IX of the ASME Boiler and Pressure Vessel Code.
6.12.2 Pipe Thread Tapping. Holes may be tapped in the wall of a fitting if the metal is thick enough to allow the effective thread length specified in Fig. 11 (Fig. 11-11 of Mandatory Appendix II). Where thread length is insufficient or the tapped hole needs reinforcement, a boss shall be added.
6.12.3 Sockets. Sockets for socket welding connections may be provided in the wall of a fitting if the metal is thick enough to afford the depth of socket and retaining wall specified in Fig. 12 (Fig. 11-12 of Mandatory Appendix 11). Where the wall thickness is insufficient, or the size of the connection requires opening reinforcement, a boss shall be added (see Fig. 13 (Fig. 11-13 of Mandatory Appendix ll)J.
6.12.4 Butt Welding. Connections may be attached by butt welding directly to the wall of the fitting Isee Fig. 14 (Fig. 11-14 of Mandatory Appendix 11)]. Where the size of an opening requires reinforcement, a boss shall be added.
