Product Description
Industrial-Grade Non-Asbestos Sealing Sheets for Hydrocarbon Service
Compatible With Crude Oil, Natural Gas & Steam Systems, Safe & Asbestos-Free for Oilfield Use
H1 – Product Introduction
This industrial-grade non-asbestos sealing sheet is specially engineered for hydrocarbon service in oilfields, crude oil pipelines, natural gas transmission systems, and combined steam facilities. Formulated with high-tenacity aramid fibers and oil-resistant elastomeric binders, it provides stable, long-lasting sealing performance under severe pressure, thermal cycling, and continuous exposure to petroleum-based media.
Fully asbestos-free and designed for safe field operation, this material meets strict health, safety, and environmental standards for oil & gas production, transportation, and processing facilities. It delivers reliable sealing for crude oil, natural gas, fuel mixtures, steam, and associated process fluids — making it ideal for oilfield operations, compressor stations, pipeline flanges, and energy infrastructure in major oil and gas-dependent regions.
H2 – Core Performance Benefits
- 100% asbestos-free composition for safe oilfield and industrial use
- Excellent resistance to crude oil, natural gas, hydrocarbons, and petroleum derivatives
- Stable sealing under high temperature, high pressure, and repeated thermal cycling
- Low stress relaxation to maintain bolt load and reduce leakage risk in long-distance pipelines
- Strong compatibility with steam systems and mixed oil‑gas‑steam service conditions
- Easy to cut, machine, and install for on-site maintenance and project installation
H2 – Material Structure & Production Method
Produced via precision hot-compression molding to ensure uniform density, consistent mechanical properties, and reliable sealing across the entire sheet.
