HY8201 Metal Octagonal Gasket
Solid metal ring gasket with an octagonal cross-section (approximately rectangular with chamfered edges), precision-machined from high-strength metal.
Technical Specifications
Pressure: 0–70 MPa (higher values possible, depending on material and standard)
Temperature: -200~800 ℃
Chemical suitability: pH 0–14
Application Media: High-temperature/high-pressure steam, hydrogen, oil and gas mixtures, sour gas (containing H₂S), liquid ammonia, molten salts, and other highly corrosive or high-risk process media.
Application Areas: Widely used in BX or R-type flange connections for oil and gas exploration and transportation, hydrotreating in refineries, chemical synthesis, power generation, and marine engineering. Ideal for high-pressure valves, wellhead equipment, separators, heat exchangers, and long-distance pipelines requiring ultra-high-pressure static sealing with exceptional reliability.。
