Perhaps the B31.1 experts can help me understand an issue regarding unions.
B31.1 106.3 states that Class 3000 steel pipe unions, constructed in accordance with MSS SP-83, may be used provided the system design conditions are within the standard's listed pressure-temperature ratings.

I've installed equipment where the supplier gave 8.8 bolting for carbon steel to carbon steel. The application is wet. Now I know enough to say that A2-70 and A2-80 are not quite up to the yield strength of an 8.8 fastener. However, I'd like to change out the fasteners to stainless steel, but...
Does anyone have experience with bolted shaft couplings that employ a friction modifier between flange faces, such as an anaerobic acrylic adhesive (possibly from a certain threadlocker manufacturer)? Can anyone suggest a type that provides high shear strength, but doesn't harden? I'd like to...
Hi All,
I'm a mechanical engineer working at a hydropower plant. The turbine guide bearing takes quite a beating, and they've asked me to look into a larger diameter stud and/or different material.
The current arrangement is a threaded insert welded in place in a thick walled tub/cylinder...
We're preparing to assemble two bolted joints, which are drilled for bolt heaters (induction, or other). The manufacturer is unable/unwilling to give us procedures to assemble them, other than to tell us the required stretch to target.
My initial thought is that all the bolts should be...
I'm interested in digging deeper into Hydraulic machinery, francis, kaplan, peltons, etc, and to understand the theory behind them better. The books I'm seeing are all written by East Indian and Chinese authors. Now, not that I doubt their authority on the subject, but is there an introduction...
I'm trying to use a Variable Section Sweep in order to cut an involute gear tooth profile through a helical datum curve.
I have 2 involute datum curves that define the section I want to cut. I'm using 'use edge' in sketcher to define the cut sketch.
The involutes and the trajectory I want to...
