Is there a web link where I can find the various coefficients of expansion thru a range of teperatures for SA - 387 Grade 11? Thanks Abi

Say you have an extremely complex system; many major runs, many complex branches. You want to determine the CG of several portins of the piping. You could create a (new name) file with all other portions of the system deleted; add an anchor somewhere, do a batch run, then look at location of...

Where is it on Caesar???????? Suppose you have an input as a Word file, and you want to make a few changes, and save it as a separate file, or put that new file in a different folder. It is easy to do. How to easily do the same thing with CII, ver 5 (patched)? Why doesn't Caesar have a...

For Ver. 5.0, any load case, using the Static Output Processor; How can you arrange the output of stresses to display an order of Highest stress down to Lowest stress vs. Node Numbers?

Nine Entry Windows - Vectors 1,2,3 and Gx,y,z In order to achieve correct results: Is it necessary to enter either values or zeroes in all nine windows, or can 'zero' entries be left blank?

Given that positive Y usually points up skyward in various packaged engineering programs, then what is the usual orientation of X and Z relative to 'Plant' North?

We have a plethora of small steel weldments, ie: knee braces, usually 3x 3x 3/8 x 4 foot overhang Short pipe stands with end 1/4" plates, 4'WF usually 4 ft high 6 ft sq low level platform step-ups about 21" high All are C.S. and primed / gray spray epoxy Need is to rough cost for domestic...

Please explain the meaning of the phrase "to jeep a pipeline"

Does OSHA require a Vertical Toe Plate all around edge of any/all walking /standing platforms, no matter the platform area or height off grade? Are there exceptions, i.e. say you have a four footspanthat sits on grade and merely crosses a shallow ditch ... would it still be required in such a...

There are so many organizations with their own pipe specifications. What is special about API 5L various grades. In Grades A nab B, it has same yield as ASTM A53, A106, so why use the API? In grade X42, it is only 2,000 psi better than A106 Gr C, and it is matched in yield by most of the ASTM...

I have an electronic copy of B31.4 and am going blind trying to confirm that Maximum Pressure Allowable per the Barlow Formula is based on pipe with a maximum wall thickness of 87.5% of nominal wall because of manufacturing tolerance of -12.5%. I am looking for a paragraph that says that after...

Is it used for instrumentation in helium service? What does such an item do?

Many pages of each code address the same subject matter with only minor differences between them, e.g. stress allowables for various materials as a function of temperature. But is there a general written reference / synopsis which addresses the MAJOR differences between say process, power, gas...

I am looking at a drawing which shows a RFSO welded to the small end of a concentric reducer. I do not think such a thing can be done with ASME reducers, or any other standard reducer. What is needed is a Weld-Neck. Is there something I am missing here?

When does a Pressure Vessel become a Pipe and vice-versa? Is there a minimum diameter for a Pressure Vessel?

It is my belief that, per code, skirts on vertical pressure vessels must have a minimum thickness equal to the vessel wall. True? Also, that unless thicker than vessel wall, OD of skirt must match OD of vessel. True?

For centrifugal compressor, say that Inlet is 150 degF at 20psig and Outlet is 500 degF at 40 psig, I would expect that the Volute temperature would be at least equal to the outlet temperature of the gas. Probably higher due to efficiency / frictional etc. losses. Excluding other losses in the...
