Discussion Overview
The discussion focuses on selecting appropriate materials for a high-pressure face seal designed to withstand internal gas pressures of 3000 psig. The context includes considerations of material properties, seal design, and operational conditions such as temperature and gas chemistry.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- Blake J raises concerns about using elastomer face seals at high pressure and the potential for issues with the threaded connection made of aluminum.
- Baluncore inquires about the size of the retaining part, the temperatures, and gas chemistry involved, suggesting that flat ceramic face seals may be suitable for rotating connections.
- Baluncore describes the O-Ring Face Seal (ORFS) design and its functionality at high pressures, indicating it works well with hydraulic fluids.
- Blake J indicates a preference for using an elastomer seal, noting that it will be a static seal for inert gases without temperature extremes, and expresses confidence in avoiding extrusion issues with proper design.
- Another participant mentions that elastomer seals may not be suitable for dynamic loads, suggesting a different approach may be necessary.
Areas of Agreement / Disagreement
Participants express differing views on the suitability of elastomer seals for high-pressure applications, particularly concerning static versus dynamic loading conditions. No consensus is reached on the best material or design approach.
Contextual Notes
The discussion lacks specific details on the dimensions of the retaining part and the exact gas chemistry, which may influence material selection. There are also unresolved considerations regarding the impact of dynamic loads on seal performance.
