Anotace textu normy ASTM F1792-97(2021) :
This specification covers the special requirements for valves used in gaseous oxygen service. The pressure containing/retaining envelope, bellows, and end nipples, shall be made of nickel-copper alloy. Internal trim which is in contact with the line media shall either be made of nickel-copper alloy, bronze, nickel-aluminum-bronze, Inconel alloy 600, brass or other materials which are compatible with oxygen service. Non-metallic seat, seat insert, or seals shall be manufacture from either TFE, reinforced TFE, CTFE, plastic, polyamide, or PEEK. Materials for lubricants shall be halocarbon, Dupont, Barycote 601, or other lubricants compatible with oxygen service. Valves shall be constructed to minimize the possibility of initiating ignition in gaseous oxygen service. Valves shall be constructed to minimize oxygen escape in the event of an internal or external fire. This shall be accomplished by pressure-boundary sealing, internal seating and pressure surge. The manual valves shall be of the packless design, with the stem sealed by a bellows.
