Technical Specifications:

Pressure: 0～70 MPa (can be higher, 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.

Applications: Widely used in oil and gas exploration and transportation, hydrotreating, chemical synthesis, power generation, and marine engineering for BX or R type flange connections. Ideal for high-pressure valves, wellhead equipment, separators, heat exchangers, and long-distance pipelines requiring ultra-high pressure static sealing with exceptional reliability.
