Valves – Flanged, Threaded, and Welding End
ASME B16.34 covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and wafer or flangeless valves of steel, nickel-base alloys, and other alloys Wafer or flangeless valves, bolted or through-bolt types, that are installed between flanges or against a flange are treated as flanged-end valves. Alternative rules for NPS 2½ and smaller valves are provided.
This standard is to be used in conjunction with equipment described in other volumes of the ASME B16 Series of Standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.
Crotti valves are made of different materials, including customized ones, offering an advantageous cost. Technical upgrading and constant staff training are the basis of our fast and efficient industrial production, planned in compliance with PED, ATEX, API 6D, Fire Safe and Fugitive Emission Test standards.
