    Butterfly Valves

    I've been doing some research into butterfly valves lately. My industry is power plants and power production (B31.1). I have come across a range of face to face dimensions for wafer/lug butterfly valves via B16.10, MSS-SP67, MSS-SP68. Typically when I specify a valve the dimensions match up with...

    STUD Bolt ASME standard

    In addition to XL83NL's comments, a stud bolt (B16.5) is not the same as continuously threaded stud (B18.31.2) per the definitions in B18.12. There's truly not much difference between a B16.5 stud bolt or a B18.31.2 continuously threaded stud. Through talking with bolt experts and companies...

    Storage of Contaminated/Used Fire Water

    Thank you very much Stookeyfpe! I believe this is what I was looking for. Did some research and the state this is located in has fully adopted the IFC thus the IFC code should be used in place of the NFPA code. A co-worker has stated that in NFPA 850 there is wording that covers this topic for...

    Storage of Contaminated/Used Fire Water

    Hello, Could someone provide me some guidance on the following? I am trying to size a Oily Water Storage Tank (atmospheric pressure) to gather runoff of firewater in the event of a Oil Storage Tank rupture inside of a building. To clarify, if a Oil Storage Tank (Lube Oil) were to rupture and...
