Does anyone know if testing is required on crimped hose connections to meet ASME 31.3 requirements.

I am looking for the dew point temperature.

The equation is: PV=nRT =mRT/M This translates to: Pv=RT/M where v is the specific volume and R is the universal gas constant. I do not know M or v. I am given: P=350 psi T=160 F Relative humidity = 40% How do you calculate molecular weight or the specific volume?

It is asking me to upgrade to the professional engineering edition. Do you what this means.

I know my relative humidity, temperature, and pressure, and I am trying to find the specific volume. I do not know the quality. Any help is appreciated.

I have a solid copper wire (.080 cross section) and used as a static face seal inside a groove on a flange. I am wondering what the seating stress is. According to ASME Section VIII BPVC on table 3-320 they list a ring joint gasket with a seating stress of 18,000 for iron or soft steel. Should I...

I am not sure that I can apply the ideal gas law in high temperature and pressure conditions. I will be around 1000 psi.

I used a sonic nozzle to measure the flow rate of a compressor. The nozzle was located at the discharge of the compressor. I have found my flow rate in CFM with respect to the pressure drop and temperature at the nozzle. To my understanding this is CFM (not ICFM, ACFM, or SCFM). I want to...

I know that the working pressure is 275 F. I was wondering what the factor of safety is included in this rating.

I am wondering what the factor of safety is on ANSI B16.5 150# stainless steel 300 series flange. My operating conditions are 120 F and 400 psi.

Does anyone know the yield stress of: G4000 gray iron casting with a tensile strength of 40 ksi 65-45-12 ductile iron casting with a tensile strength of 65 ksi

The casting has a tensile strenght of 40 Ksi and the bolt has a tensile strengh of 150 Ksi. Thus, shouldn't the threads on the casting fail before the bolt. I have an older version of the engineering handbook but I did not see anything on the internal thread strength of iron castings.

What is a good rule of thumb to determine the clamping force required with respect to the preload.

The depth of the tap is .94 inches and the depth of the drill is 1 inch. The plating on the bolt is yellow dichromate.

I have a 7/16 Grade 8 standard steel bolt with a tensile strength of 150,000 psi which threads into a casting made of either: Ductile iron type 65-42-12 -> tensile strength = 65,000 psi Gray iron type G4000 -> tensile strength = 40,000 psi I am looking for the torque specs of both castings...

The 1470 psi rating on butt weld fittings are for schedule 80 pipe.

Does anyone know if there is a weld that will withstand 2500 psi on the end cap/plug of a pressure vessel. The butt weld fittings are only good for up to 1470 psi. I am using a 5" diameter pipe.

Does anyone have a copy of ISO 5167-1 and 2 that they could send to me. I would really appreciate it. Why are pipe taps no longer allowed?

Does anybody know the correct spacing for pressure taps before and after an orifice plate. I read in a book that D and D/2, Flange, and corner taps were recommended. However, the same book also had a figure for the pressure tap locations at 2D and 2D. Also, where is the best location to mount...
