I am revising a piping materials spec. that has A234 WPBS listed as the material for fittings. In the ASTM book (I only have '97) it states that you can specify a welded fitting by supplementing the letter "W" to the grade and marking symbol (A234 WPBW). The version of MSS SP-25 I...
Anyone have any experience with using SA-354 or SA-540 bolts for subsea hydrocarbon P/L service? Would chloride stress cracking, cad plating, saltwater, or brittleness be an issue? We are looking for an alternative to a 193-B7 stud, we need 29-30 ksi allowable, 3 1/2" Dia.

We have a Sec VII, Div 1, Appendix 2 designed flange. The allowable stress for the bolting material should be per Div. 1 Table UCS-23 (we are using a 3 1/2" B7 - 23,000 psi allowable). Can we use twice the allowable stress (46 ksi) per Sec VIII, Div. 2, Appendix 4, 4-141? Does this...
A 28" CL 1500 flange has been designed per ASME Sec. VIII, Div. 1, Appendix 2. Anyone know how it can be shown that a R101 28" ring joint gasket is good for 3705 psi? If it is not, how does one go about calculating the required dimensions to design their own? [flush2]
