VP104-85 for Sour Gas Sevice
Resistance to the explosive decompression (ED) damage caused by high pressure hydrogen sulfide is one of the primary requirements for seals in the oilfield.
Explosive decompression is caused when a high pressure gas permeates into a seal material. Because permeation is a very slow process, the gas becomes trapped within the bulk of the elastomer if the system pressure drops suddenly. The trapped gas expands as its pressure drops, quickly causing localized areas of extreme tension with the rubber material. If the material is stretched beyond the breaking point, blisters, splits, and cracks form in the material.
Product Highlights:
- Exposure to high pressure sour gas
- Exposure to completion fluids
- Exposure to crude oil
- High temperature oilfield applications
Explosive Decompression Resistance
Resistance to the explosive decompression (ED) damage caused by high pressure hydrogen sulfide is one of the primary requirements for seals in the oilfield.
Explosive decompression is caused when a high pressure gas permeates into a seal material. Because permeation is a very slow process, the gas becomes trapped within the bulk of the elastomer if the system pressure drops suddenly. The trapped gas expands as its pressure drops, quickly causing localized areas of extreme tension with the rubber material. If the material is stretched beyond the breaking point, blisters, splits, and cracks form in the material.
The relatively high concentration of hydrogen sulfide (H2S) in sour natural gas is notorious for degrading elastomer seals used in downhole applications. Traditional fluorocarbon (FKM) and perfluoroelastomer (FFKM) seal materials tend to suffer from explosive decompression with exposure to H2S. While this problem is not as severe with HNBR and Nitrile (NBR) elastomers, these materials are limited in the their thermal stability and tend to harden and get brittle in long- term, high temperature exposure to H2S.
The base polymer used in VP104-85 has been tested in various combinations of sour gas service and has outstanding resistance to explosive decompression in sour gas.
In addition to sour gas, VP104-85 also has excellent resistance to acids, bases, amines, hot water, steam, hydrocarbons, and methanol.
VP104-85 is recommended for use in O-ring and energized lip seal applications as well as custom engineered seal and non-sealing elastomer applications.
VP104-85 +10°F to +400°F (-12°C to +200°C)
VP104-85 has significant advantages for the Energy, Oil and Gas industry compared with other elastomer seal materials:
Compared to perfluoroelastomer (FFKM)
- Better explosive decompression resistance in sour gas
- Lower cost
Compared to standard A-type fluorocarbon (FKM)
- Better explosive decompression resistance in sour gas
- Better amine resistance
- Better base resistance
- Better methanol resistance
- Better steam / hot water resistance
Compared to hydrogenated nitrile (HNBR)
- Better explosive decompression resistance in sour gas
- Better steam / hot water resistance
- Better acid / base resistance
- Better high temperature performance
Compared to high-temperature nitrile (NBR)
- Better explosive decompression resistance in sour gas
