This Standard applies to new valve construction and covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated valves.
This specification covers alloy steel castings for valves intended primarily for high-temperature and corrosive service.
Selection will depend on design and service conditions, mechanical properties, and the high-temperature and corrosion-resistant characteristics.
The grades covered by this specification represent materials that are generally suitable for assembly with other castings or wrought steel parts by fusion welding. It is not intended to imply that these grades possess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish for himself a suitable welding technique.
Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.
- A description of the casting by pattern number or drawing (dimensional tolerances shall be included on the casting drawing)
- Grade of steel
- Options in the specification,
- Whether the castings are to be produced using the investment casting process, and
- The supplementary requirements desired including the standards of acceptance.
Refer to ASME B & PV Code Section II for non-identical A/SA requirements.
