explosive decompression

rap·id de·com·pres·sion

sudden severe expansion of gases due to a reduction in ambient pressure.

explosive decompression

In aviators or divers, decompression resulting from an extremely rapid rate of change to a much lesser pressure. This may occur if a high-altitude aircraft suddenly loses its cabin pressure or if a diver ascends rapidly. Either of these causes violent expansion of body gases.

The new value design uses high-nitrile Buna composites as sealing material to counteract the problem of explosive decompression. High-nitrile Buna has a much higher density than normal Buna and is resistant to internal pressurization even when subjected to 600 psi and higher.
Figure 5 shows that vulcanizates based on HNBR elastomer are highly resistant to explosive decompression. Dry carbon dioxide at 5.2 MPa (750 psi) was used in the test to evaluate explosive decompression resistance.
Figure 6 shows the effect of explosive decompression testing on tensile strength.

The increase in both operating temperature and pressure of the R134A has created problems with the elastomers in both thermal stability and explosive decompression in elastomeric seal boots, orings and hose liners.
Subsequent explosive decompression testing demonstrated the N220-elastomer combination to have the best XDF performance.
In high pressure gas applications, a common problem is explosive decompression. This problem is indicated by the random short splits or ruptures going deep into the o-ring cross section.
With regard to rubber products, there has been a significant amount of work done in the last few years with respect to explosive decompression in products used in the oil field and with improving the life of tank treads.
One of the modes by which these seals fail is by gas decompression blistering, commonly known as explosive decompression, which causes the elastomeric component to become the limiting factor in the performance of oilfield equipment.
