I registered and downloaded the synopsis. It was very easy and only took a few hours for my registration to clear. There is a very helpful chart showing which states require NBR. Michigan is not one of them. North Carolina is.

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...

Hi davsy, ISA classifies pressure control valves in SP20 form 51. Relief valves are SP20 form 53. HG

Per the Instrument Society of America: Safety Valve (PSV): An automatic pressure relieving device actuated by the static pressure upstream of the valve and characterized by full opening pop action. It is used for gas or vapor service. Relief Valve (PRV): An automatic pressure relieving device...

So, to summarize: PRV for liquid service PSV for gas service PSRV for liquid and gas service

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.

4-12ma controls the coolling valve with 4ma full open 12-20ma controls heater with 20ma full on I would like to have one 4-20 ma controller setpoint input and two 4-20 ma outputs, with one of the 4-20 ma outputs inverted compared to the other.

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

Comet is correct! So why does bleach remove the stain...on a chemical level?

One of the above cleaned it in seconds. Which one and why?

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

Do the values above seem excessive for a 1.5" 150# flanged nozzle into a 3" sch 40 pipe body?

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"

We have each resistor spaced about 1.5" apart and eighteen (18) are connected in a row. Again, this is the wye part of a three phase circuit. The bus bar is limited to 50 amps, but the circuit is pulling 190 amps total. Is there a way to calculate the current flowing thru each bus bar?

For this application the voltage is 480V and the load is balanced. The total length of the wye bus barr is approximately 18 inches. I am considering the current flow through the buss bar between the resistors (heater elements). It appears to me that since the wye buss bar has zero voltage...

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?
