Which states require national board registration for ASME pressure vessels? I believe North Carolina does. Does Michigan also require it?

If a medium voltage is rated 4160 in the US, what is the equivalent voltage in France?

I apologize if this topic has been discussed, but the search function is down and Google didn't pull up anything on this topic. A paint spec says for carbon steel, "When using inorganic Zinc under insulation, do not apply on piping or vessels operating between 50F and 250F as the zinc reverses...

Please clarify when to use a PRV, a PSV and a PSRV. Is the difference application specific or code specific? Please identify (PRV, PSV and PSRV) on the following ASME pressure vessels: Thermal relief valve on liquid containment: Thermal relief valve on gas containment: Fire relief valve on gas...

When does year built apply? The year it was designed or the year it was hydrotested? Or are we allowed to decide? TYIA, heaterguy

Would you mind sharing with me the yearly quantities produced and ballpark prices of industrial gas turbines from the likes of GE, Solar, Siemens, Pratt&Whitney, etc.

Can someone recommend a split range controller? We like to use recognized brand names in our panels.

The white inside surface of my coffee mug had tea stains. Which cleaner removed the stains easily and why? 1. 409 2. Comet 3. Windex

If a customer gives Fx-500 pounds, Fx-500 pounds, Fz-500 pounds, Mx-1,500 foot-pounds, My-1,500 foot-pounds, and Mz-1,500 foot-pounds, do we apply all six forces at once, one at a time or just F or M forces? "Each vessel nozzle shall be designed for the following loads"

Does AC current flow in a parallel wye common? For instance, you have eighteen wye resistor circuits and the common is connected with buss bar. Does current flow thru the buss bar between the eighteen circuits?

Does someone on this board know about the newly effective KAIC rating of components inside of UL 508A panels? Our problem is the unrated solid state relays are now only rated for 5 KAIC. Accordingly, the newly effective UL 508A rules imply 5 KAIC is the rating of the panel with these relays. Of...

We fall into UG-39(b)(2) as far as spacing and hole size, but since we fill the holes with heater rods and weld the rods to the flat head, is it really an opening?

Did ASME make a published response to WRC 429?

How difficult is it to use CosmosWorks - dynamics version - to model seismic loading on horizontal and vertical pressure vessels? I have been told that it is a very specialized calculation that requires years and years of experience to perfrom.

For Pb+Pl < 1.5 Sm, are Pb and Pl average or peak stresses?

From Figure 4-130.1 "Stress Categories and Limits of Stress Intensity", what stress classification(s) should be used for a blind flange that is bolted to a pressure vessel: Choices are: Pm - Primary General Membrane Pl - Primary Local Membrane Pb - Primary Bending Q - Secondary Membrane plus...

Where can I find the material properties of SA-105, SA-182-316 and SA-182-304 at various temperature, in particular 316 stainless steel forgings at 850 deg. F? Elastic Modulus Poisson's Ratio Shear Modulus Mass Density Tensile Strength Yeild Strength

I say stupid to kill myself before getting burnt from the flame throwing that's about to commence. ASME requires a safety factor of 3.5 for yield strength design vs. actual, right? Why then can ANSI flanges not have the same requirement? They seem to have a safety factor of one! TYIA, heaterguy

Will Incoloy 800 have any problem operating in -100 deg. F inside of a pressure vessel designed for -265 deg. F? The electric heater inside of a liquid blow down tank has an Incoloy 800 sheath.

I quote: U-1(c)(2) based on the Committee's consideration, the following classes of vessels are not included in the scope of this Division; however, any pressure vessel which meets all the applicable requirements of this Division may be stamped with the Code U Symbol: (f) a vessel for...
