Acid-resistant, high-temperature, zero-leakage — comprehensive perfluoroelastomer sealing protection from refining units to pipelines
Petrochemical media are highly corrosive, high-temperature/high-pressure, flammable and explosive. Seal failure causes not only property damage but potentially catastrophic safety incidents.
HF, concentrated H₂SO₄, HNO₃ chemically attack conventional seal materials, causing failure within hours
Cracking furnaces and reformers operate continuously at 300°C+, causing rapid loss of elastomer elasticity
Toxic/flammable media micro-leaks accumulate, causing environmental contamination and safety risks
Each operating condition corresponds to a proven product combination — not standalone sales. Full technical support from selection to installation.
ApexSeal FFKM spring-energized seal: withstands 327°C, resists virtually all chemical media (including HF, fuming HNO₃). PTFE-modified jacket + Hastelloy C-276 spring. Preferred for PTA/refining/fluorochemicals.
FusiSeal metal-graphite spiral wound gaskets: stainless steel skeleton + flexible graphite fill. Temperature range -200~550°C, Class 150~2500 pressure rating.
PTFE+carbon fiber jacket spring seal + perfluoro O-ring combination. For HCl, H₂SO₄, HNO₃ storage tanks and transfer pump shaft/flange sealing.
Yiran® MT/HT/UHT series: 120~350°C+ continuous operation. For refinery exhaust treatment and catalyst regeneration tail gas. Glass fiber media + SS frame, ISO 16890 certified.
CarbActiv + ChemGuard series: activated carbon/chemical impregnation/hybrid media. Removes H₂S, SO₂, VOCs, NH₃. For tank vent, chemical warehouse, wastewater exhaust.
Every plant has unique operating conditions. Our application engineering team can visit your site for measurement, media analysis, and operating condition assessment to provide targeted seal selection and failure analysis.
