AED
AED Explosive decompression also known as Rapid gas decompression is a structural failure in the form of blistering, internal cracking that occurs due to gas permeation into the sealing material. SEAL EXTRUSION Seal extrusion occurs when a gas or liquid at high pressure forces the seal material into the clearance gap between the mating surfaces. The greater the diametric clearance and the higher the differential pressure, the more likely extrusion will occur. Weakening of the polymer due to elevated temperature and/or chemical attack or swelling also influences potential for seal extrusion. The rubber seals contains pores and rigid inclusion during the production,fluids and gases in contact with elastomer surfaces are absorbed into the material. The absorbed gas diffuses into the elastomer until fully occupied. During high pressure the gas which is absorbed will be in the compressed state. When the external pressure is suddenly reduced the compressed gas exp...
