In calculating the radius, R1:
Long radius = 1.5 * Pipe Diameter
Is the diameter the outside diameter OR the values taken from ASME B16.9 which are the inside diameter.... or the stated nominal pipe size.
Which diameter is used?
Ok so lets say we have the following:
B7 Bolt UNC 8, 105ksi yield
Bolt Diameter = 1.5 (D)
Lets say target bolt stress = 60% of yield, 63ksi.
K = .16
Using ASME PCC-1 bolt root area - that gives Target Torque , T =(K D F / 12) ft-lbs = 1772.788205 ft-lbs
So in theory - we apply the bolt...
I have an existing in-service header box (rectangle, corner joints). The design code is ASME 8 1992.
In observing appendix 13 (ASME 8 2017) - the box in question resembles that of Figure 13-2(a) (1).
There are stress calculations within the code. However my U1A provides:
MAWP: 900psig @...
So i follow: ASME PCC-1 Appendix O-3 SIMPLE APPROACH
Condition here is that:
This Appendix outlines two approaches: the simpler
single-assembly bolt stress approach (which is simpler
to use, but may result in damage to joint components);
and a more complex joint component-based approach
that...
