Metallic Seal Rings for High Temperature Reciprocating Hydraulic Service

2011-12-19
CURRENT
AIR1077A
An attempt has been made to consider all features of seal ring design including configuration, materials, hardness, dimensions, surface finishes, surface treatment, leak testing, and general quality. In addition to this, allowable cylinder breathing and general quality requirements of mating hardware are discussed. Also, at the end of this report, there is a brief paragraph on other types of seal rings.

Sealing Techniques for Missile Applications

ARP1833A
The purpose of this standard is to provide the missile hydraulic and pneumatic component designer with information learned, tested and substantiated in correction of problems and failures experienced with seals that are subject to the unique requirements of missile static storage and subsequent dynamic operational conditions. Missile hydraulic and pneumatic component designers have been handicapped by the absence of concise design criteria for two difficult sealing conditions usually existing in missile applications as follows: Static pressure condition - Low pressure for long periods in a cyclic temperature environment (i.e., long term storage requirements). Dynamic pressure condition - High pressures suddenly applied in an extreme temperature environment (i.e., operational firing requirement).
