When secondary membrance stress plus bending occurs,
3Sm may be used.
In this case, 3S is greater than its yield stress.
Does It means yield or deformation of shell.
Secondary is self-limiting.
I considered the load which are acting on shell to be attached lifting lug and tailing lug
as...
For fixed tubesheet with hub welded to shell(Refer to Fig. UW-13.3),
If Allowable stress of tubesheet is lower than allowable stress of shell,
Shall Hub end thickness be checked as per UG-27 consider hub as cylindrical shell Or May hub end thickness be equal to shell thickness?
Please reply...
This para. shows "When the long dimension of opening exceeds twice the short dimentions, the additional
reinforcement is required.".
What does additional reinforcement mean?
i have a question about RT efficiency in preparing calculation sheet.
1) From datasheet, shell side is spot.
In calculation, if you use seamless head and rolled plate for shell.
what is E for shell?
what is E for seamless head?
So, What is the right one of RT-1, RT-2, RT-3 and RT-4 for stamping...
Before i use compress to prepare the strength calculation sheets in my company, i decided governing temperature using FIG UCS-66 curves.
Compress for windows uses the MDMT reduction of FIG UCS-66 1 to decide the rated MDMT.
Which one of FIG. UCS-66.1 and FIG. UCS-66 curves
is good to establish...
