When pipeline systems demand uncompromising sealing performance under extreme conditions, the MICA Filled Gasket stands as a proven solution. As a dedicated China Manufacturer with decades of experience in critical-service sealing components, we engineer this gasket to meet the rigorous requirements of high-pressure, high-temperature applications—particularly where fire safety, chemical resistance, and long-term reliability are non-negotiable.
This specific gasket is manufactured to ASME B16.47 B standards, Class 300#, with a nominal size of 36 inches. Its construction features a SS 347 outer ring, a SS 347 inner ring, and a SS 347 winding hoop, all complemented by a filler content of 98% high-purity MICA. The use of SS 347 throughout the metallic components ensures excellent resistance to intergranular corrosion and stress cracking, especially in elevated-temperature services where stabilized stainless steels are preferred.
The winding process—alternating precision-formed metal strips with dense MICA filler—creates a resilient, compressible seal that accommodates flange movement, thermal cycling, and pressure fluctuations. Unlike graphite or PTFE-filled alternatives, MICA offers superior oxidation resistance, does not promote galvanic corrosion, and maintains its structural integrity at temperatures exceeding 800°C. This makes the MICA Filled Gasket particularly suitable for critical services such as refinery transfer lines, steam systems, heat exchangers, and catalytic cracking units.
Typical application scenarios include:
- Oil and gas production: wellhead connections, flow lines, and offshore platforms where fire-safe seals are mandatory.
- Petrochemical processing: reactors, distillation columns, and high-temperature piping handling aggressive hydrocarbons.
- Power generation: superheated steam lines, boiler outlet connections, and turbine bypass systems.
- Fertilizer and syngas plants: where ammonia and hydrogen permeation must be effectively contained.

As a reputable China Manufacturer, we combine strict quality control—from raw material traceability to in-process dimensional inspection—with full compliance to ASME and ASTM standards. Every gasket is individually tagged and packaged to prevent damage during transit. For the 36-inch Class 300 configuration, we ensure precise control over winding density, outer ring fit, and inner ring alignment to guarantee leak-tight performance at rated pressures and temperatures.
Selecting the correct gasket involves matching size, pressure class, filler material, and ring materials to the actual service environment. Our engineering team provides application-specific guidance, including bolt load calculations and flange surface finish recommendations, to optimize seal performance. With a track record of supplying to major EPC contractors and end-users across five continents, we stand behind every MICA Filled Gasket with full documentation, test reports, and after-sales support.
For critical sealing challenges, trust a China Manufacturer that prioritizes material integrity, manufacturing precision, and operational safety—delivering gaskets that perform as reliably on day one as they do after years of service. Contact us for detailed datasheets, third-party test certifications, or custom sizing beyond standard ASME ranges. Your process safety is our engineering priority.
