Jacketed Metal Gasket

No.LL-IFG-03

Jacketed Metal Gasket refer to composite gaskets that use non-metallic materials (flexible graphite, asbestos rubber sheet, ceramic fiber, etc.) as the core and are clad with thin metal sheets via special processes. Classified by cross-section, they are generally divided into two types: flat-clad type and corrugated-clad type. They are one of the most traditional sealing gaskets.

Description

Core Features

· Precision-machined concentric serrated/corrugated profile on solid metal face.

· Available in 304/316L stainless steel, carbon steel, and alloy options.
· All-metal construction; optional graphite/PTFE coating for dual-seal reliability.
· Custom sizes & standards: ASME B16.20, HG/T 20592, and RF/MFM ring joints.

Technical Advantages

1. High-pressure & high-temperature resistant sealing for severe service.

2. Excellent anti-fatigue performance under cyclic loading conditions.

3. Low bolt-load requirement while maintaining tight sealing integrity.

4. Durable, reusable, and long service life, reducing maintenance costs.

Product Application

Ceramic fiber gaskets, with high temperature resistance, thermal insulation, chemical stability, and eco-friendly lightweight features, are applied in high-temperature industries as follows:

Metallurgy: Sealing/insulation for ladles, tundishes, submerged nozzles, furnace doors, flue flanges, furnace walls, and furnace cars (≥1000℃).

Petrochemical & Power: Sealing/insulation for boiler roofs, flue/pipeline flanges, turbine/generator components, refinery heaters and reactors (resists high-temperature flue gas/media).

Kilns: Sealing/insulation for ceramic/glass/refractory kiln doors, wall joints, observation ports and kiln furniture (cuts heat loss, improves efficiency).

Others: Aerospace (temporary insulation for engine test benches); Building Materials (sealing/insulation for cement rotary kilns, gypsum furnaces); Environmental Protection (sealing for waste incinerator flues/furnaces).

Attention: Avoid prolonged contact with strong alkaline media; use alkali-resistant coatings or alternative gaskets instead.
