DIPTI METAL INDUSTRIES
Flexible Graphite Gaskets: Unrivaled Performance Across All Grades in Extreme Conditions
Dipti Metal Industries manufactures pure and reinforced flexible graphite gaskets for high‑temperature, high‑pressure and corrosive services in power, petrochemical and process plants worldwide.
🏭 About Dipti Metal's Flexible Graphite Gasket Expertise
Dipti Metal is a global manufacturer, exporter and supplier of Flexible Graphite Gaskets covering the full spectrum from homogeneous (pure) grades to metal‑reinforced constructions. Produced from exfoliated natural graphite and calendered into dense sheets, the material is asbestos‑free, resists thermal cycling and maintains seal integrity over a wide temperature range.
We supply pure graphite in 98%, 99% and 99.8% carbon purities, and reinforced options using tanged or foil inserts in SS 304/316L/321/347, Carbon Steel, Monel® 400, Inconel® 625/825 and Hastelloy® C‑276 for elevated load and blow‑out resistance. Typical industries include power generation (steam), petrochemical, chemical processing, and furnace/exhaust service.
✨ Key Features & Benefits
- Extreme temperature range: cryogenic to ~500 °C in oxidizing media; >3000 °C in inert/reducing atmospheres
- Chemically inert across pH 0–14 (avoid strong oxidizers)
- Asbestos‑free and environmentally safe
- Excellent conformability and low gasket factors (m, y)
- High recovery, low creep/stress relaxation
- Fire‑safe grades available (API 607 / API 6FB)
- Low leakage for emissions and energy control
- No aging/embrittlement; stable under thermal cycling
- Good thermal conductivity around the seal
- Multiple reinforcements for higher pressure/blow‑out resistance
🧱 Types, Grades & Constructions
Pure / Homogeneous Graphite
98%, 99% and 99.8% carbon. Superior sealability at low bolt loads; ideal where metal inserts are not required.
- Meets common ASTM F104 graphite sheet classifications
- Service: high‑temp chemical and steam (with suitable flange design)
Tanged Metal Insert
Perforated (tanged) sheet in SS 316L/304/321/347, CS, Monel 400, Inconel 625/825, Hastelloy C‑276.
- Maximum blow‑out resistance & handling strength
- Preferred for high‑pressure steam/hydrocarbons; often fire‑safe
Flat Foil / Wire Mesh Insert
Thin metal foil or mesh laminated with graphite for tensile strength and clean facing.
- Improved stability vs pure graphite
- Used in chemical service and static elevated temp joints
Flexible graphite is also used as a filler/facing in Spiral Wound and Camprofile gaskets for critical flanges.
🏗️ Typical Applications
Power Generation
High‑pressure steam lines, turbines, boilers, heat exchangers, exhausts.
