3、 COMPRESSED GAS - AIR, OXYGEN, AND NITROGEN This specification is approved for use by Naval Sea Systems Command, and is available for use by all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification covers seamless steel flasks with integral forged heads and v
4、arious composition end plugs for storing compressed gases (air, oxygen, nitrogen, helium, or helium-oxygen mixtures). 1.2 Classification. Flasks and end plugs are of the following types, classes, and services as specified (see 6.2). 1.2.1 Types. The types of seamless steel flasks are as follows: a.
5、GF General service flask, straight design (see figure 1) b. CD General service flask, curved design (see figure 1) c. SF Air moisture separator flask (see figure 2) 1.2.1.1 Subtypes. Flasks may have more than one subtype as follows: a. A Special attachments as specified (see 6.2) b. S Skirted (see f
6、igure 1) c. W Wide outside diameter (20 inches) 1.2.2 Classes. The classes of seamless steel flasks are as follows: a. Class 3000 3000 pounds per square inch (psi) maximum allowable working pressure (MAWP) b. Class 5000 5000 psi MAWP c. Class 5500 5500 psi MAWP 1.2.3 Services. The services for seaml
7、ess steel flasks are as follows: a. Service A Compressed air b. Service B Oxygen c. Service C Oil free nitrogen, helium, or helium-oxygen mixtures 1.2.4 Plug types. Each plug type is available in a range of sizes as indicated in their respective figures as follows: a. S Straight plug (see figure 3)
8、b. R Right angle (90 degree) plug (see figure 4) c. Y “Y” plug (see figure 5) Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-22606D(SH) d. M Separator inlet/outlet plug (see figure 6) e. D Internal drain plug (see figure 7). Type D plugs can
9、 only be used as drain plugs, and not as inlet plugs. Horizontally mounted flasks and flasks mounted on an incline greater than 45 degrees from vertical require a Type D drain plug. Note that horizontal mounting of flasks is not recommended and is to be avoided whenever possible. Horizontally mounte
10、d flasks do not drain completely, necessitating increased recertification periodicity, which results in much higher life cycle costs of the flask. f. X Special plug. Type X plugs are of special design that does not comply with plug Types S, R, Y, M, or D. Type X plugs are provided in accordance with
11、 details specified by the procuring activity (see 6.2). All material, cleanliness, and testing requirements for plugs specified herein still apply. 1.2.4.1 Plug seal types. Every plug type is threaded into the flask and sealed by one of two methods as follows: a. R O-ring seal (see figures 3, 8, and
12、 9) b. W Seal weld (see figures 10 and 11) 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-22606D(SH) 1.3 Part or identifying number (PIN).
