‌Kevlar Gland Packing: Solving Industrial Sealing Challenges Through

Why Kevlar Gland Packing Outperforms Conventional Materials

When extreme conditions challenge standard gland packings – whether 550°F steam services or corrosive chemical exposures – Aohong’s Kevlar Gland Packing delivers unmatched reliability. With 14 years of field experience across global refineries, our aramid fiber sealing systems consistently transform maintenance challenges into operational success stories.

Advanced Material Science Behind Kevlar Packing

Aohong engineers optimize the β-phase crystalline alignment of aramid polymers to create high-performance gland packing that:

• Withstands 288°C continuous steam service (exceeding 260°C industry standards)
• Maintains seal integrity at PV values up to 480,000
• Reduces axial compression by 19% compared to conventional weaves

“Our 14 reciprocating compressors using Aohong’s packing have shown zero leaks since Q2 2023,” confirms Jim R., Plant Supervisor at a Gulf Coast refinery.

Field-Proven Kevlar Packing Applications

API 610 BB3 Pump Performance

Traditional graphite packing typically fails within 3 months in crude service. Our Kevlar Gland Packing solution features:

1. 45° crossply braiding for even stem load distribution
2. PTFE impregnation (ASTM F1468 verified)
3. Proprietary break-in lubricant

Installation Tip: Always stagger packing rings 90° for optimal performance.

Economic Advantages of Kevlar Gland Packing

Our aramid fiber sealing technology delivers measurable financial benefits:

• 8-month ROI (documented at 47 industrial sites)
• 23% longer service life than competitor products
• Reduced environmental compliance risks

Note: Not recommended for >30% HNO3 above 80°C (see Technical Bulletin #47).

Why Industry Leaders Choose Our Kevlar Packing

When critical seal failures occur, Aohong’s high-temperature gland packing proves its value by:

1. Resisting H2S corrosion that destroys standard packing
2. Surviving extreme thermal cycling
3. Operating smoothly after proper break-in

From offshore platforms to petrochemical complexes, our Kevlar Gland Packing consistently outlasts equipment rebuild cycles. As one veteran maintenance manager observed: “This material outlasts most plant managers’ tenures.”
