DOC Issues Final Affirmative Determination on Steel Flanges From India | Butterfly Valve Pin

Components made from carbon steel—any ferrous material having 0.29 to 0.54 percent carbon and 0.60 to 1.65 percent manganese—are considered by ASME VIII Div. I and ASME B31.3 codes as inherently ductile and therefore resistant to brittle fracture. These include A105N flanges; A234 grades WPA, WPB, and WPC seamless fittings; A106N pipe (all grades); and A53 seamless pipe. However, some components rated for service down to -20 degrees F (-29 degrees C) have been found unsuitable for such applications. Some flanges made from A105 carbon steel, operating at less than 300 pounds per square inch (PSI), and some pipe made from A106 grade B, less than ½ in. thick, have been evaluated with a Charpy V-notch impact toughness test and found unfit for service at any minimum design metal temperature lower than 68 degrees F.

Second, the valves must maintain an ANSI Class 6 sealing capability from installation until removal for refurbishment. Elimination of reverse flow results in separation between the turbine combustion process and auxiliary systems such as liquid fuel, purge air and water injection. With no reverse flow of combustion gasses into these systems, back-up fuel system availability and reliability typically exceeds 98 percent.

“The scarring documented of the palate/uvula area is almost certainly from the chemical burn he suffered from the H2S,” the report reads.

Like all thermal engines, steam plants are powered by energy differences and the greater this difference, the greater the fuel efficiency. Valves maintain the separation by isolating the high energy processes from the low energy processes. When valves leak, they are acting in direct opposition to the forces that drive the plant by allowing energy to leave the high energy processes and enter the low.

Story: The diamond-shape milling pattern on the 303 stainless-steel putter now extends across the face instead of just in the center as with past models. The shapes created by the milling pattern, including tiny horizontal grooves, channel the vibrations of impact for a softer, lower-pitched sound, smooth feel and better roll. The three new blade models are available with Odyssey’s new Stroke Lab shafts for better stroke consistency.

The ongoing investigation, which also includes students from journalism programs at Ryerson, Regina, Concordia the University of British Columbia, has obtained documents through freedom of information laws that detail growing safety concerns about H2S, also known as sour gas, dating back to 2012. Those documents were never made public.

This unique sound profile is displayed as a visualisation of your hearing sensitivity, wrapped around a circular form. The low frequencies are at twelve o’clock position, with frequencies getting higher as the you move around the circle clockwise. The further away from the middle the frequencies display, the more sensitive you are to those sounds. For our own particular hearing profile, it showed a high sensitivity to the higher-frequencies, and some fairly high sensitivity to lower frequencies, but not much in-between.
