Does anyone know of source to obtain a cast iron ASME pressure vessel? The design and manufacture of the vessel would be the responsibility of the supplier - similar to a fabricated vessel.
What stress value (safety factor)is the required reinforcement area based on? My objective is to determine the safety factor when the actual area is less than the required area. Thanks for your help.
Does anyone has a definition of what makes a pressure container an integral part of a rotating mechanical device? If you encapsulate a rotating mechanical device is the container automatically excluded from code requirements?
Are the cast iron allowable stress factors - 10 for tensile, 6.67 for bending and 5 for compression - set to minimize permanent distortion? The factors for cast iron are considerably greater than those for steel (3.5 currently).
What is the purpose of a hydrostatic test conducted at 1.3 to 2.0 times the maximum allowable working pressure? Is this primarily a leak test? Does this pressure validate the structure integrity of the component? Your opinions, comments and intrpretations are most welcome.

We are investigating the use of a swing check valve to control reverse flow at an air compressor inlet. A swing check valve was chosen to minimize flow restriction. I am under the impression that swing check valves offer the least resistance due to the straight flow path. I am concerned that...

how do you determine the fuild force on a swing check valve plate for sizing of an acutator? are there any informative sites available? Thanks for the help.
