Hongwo Sealing Gasket
When 900°F Seals Fail, Engineers Turn to Flexible Graphite Gaskets
In Singapore refineries and Indonesian geothermal plants, where traditional seals crumble under heat, Aohong’s Flexible Graphite Gaskets have become the go-to solution for flange leaks that other materials can’t fix. Here’s why:
“That batch with 4.5% density variation? Failed in Jakarta steam lines. Now we hold <5% like our plant safety depends on it.”
🔥 Engineering That Defies Extreme Heat
Our flexible graphite gaskets solve leaks with three patented breakthroughs:
- ✓ Carbon-Reinforced Matrix – 40% stronger tensile than standard graphite
- ✓ Laser-Cut Precision – ±0.1mm tolerance eliminates “ghost leaks”
- ✓ Oxidation Barrier – 2.5x longer life in cycling service
⚙️ Battle-Tested in the Toughest Conditions
Power Plants
- • Survived 500+ thermal cycles in 600°C boilers
- • Zero leaks after 18 months at Malaysia’s TNB facility
Chemical Plants
- • Resisted 98% H₂SO₄ spills that dissolved PTFE seals
- • Passed 6-month immersion tests in Singapore
Oil & Gas
- • API 6FB fire-safe certified
- • Stopped flange leaks on offshore Vietnam platforms
✂️ Custom-Built for Real-World Flanges
- • Thickness options: 0.5mm to 6.5mm (no more stacking gaskets!)
- • Metal facings: 304SS, 316SS, Monel, titanium – your choice
- • Odd shapes: We die-cut for warped or pitted flanges
“Always use spiral-wound retainers on pipes >12″ – prevents graphite blowout during pressure spikes.”

🌱 Sustainable Sealing Solutions
- ✓ 98% pure graphite – zero asbestos or toxins
- ✓ Waste recycling – scrap becomes industrial lubricants
- ✓ Energy-smart production – 30% less power than competitors
🚀 Tomorrow’s Graphite Tech Today
- • Graphene-enhanced – 15% better thermal conductivity in prototypes
- • Self-monitoring – embedded sensors detect micro-leaks early
- • Bio-based barriers – plant-derived oxidation inhibitors in R&D
Bottom line: When your flange faces superheated steam or acid baths, “good enough” seals mean dangerous leaks and shutdowns. Our Flexible Graphite Gaskets deliver uncompromising performance forged in Southeast Asia’s most punishing plants.
