I specify HVAC equipment for utility buildings; they range in size from about 10 ft square to 15 ft X 30 ft with a 10 ft ceiling. The buildings may contain switchgear, pump motors, VFDs, and controls or sometimes nothing m0re than a pump and motor.
I typically specify wall mount equipment...
I just purchased ASME B31.4 as I am working on a small fuel handling system at a diesel-fired power plant. New aboveground storage tanks will be installed along with new piping.
The plant maintenance department wants to use malleable iron fittings. Section 423.24(a) seems to be clear that...
I am relocating a section of a natural gas transmission line. The existing pipe is 16" diameter with 1/4" wall thickness. Pipe with a 3/8" wall is available.

I've been told by a tank manufacturer that per code ASME stamped air receivers are to be tested at 1.3 times the maximum allowable working pressure. Is this correct or does the number vary depending upon size and pressure?
I'm looking at steel air receivers in the 600-1200 gallon range with...
I'm looking at the inspection requirements in STI's SP001 for field erected aboveground storage tanks. The requirements include leak testing.
Can someone explain the procedure(s) for leak testing old 80k-150k gallon diesel tanks?
I have a large diesel generator located in a building and need to improve the ventilation. My calculation shows 49,000 cfm are needed for ventilation to maintain a 20 delta t in the room.
This flow rate equals about 1 air change per minute. That seems like a large number to me. Is this...
I have two 125 hp motors in a room that pump water outside the room to a clearwell. I want to know how much heat is dissipated to the room to size exhaust fans.
After reading the recent thread about heat from conveyor motors (403-174079) it seems that the heat load to the room would be 785,494...
