Oil Pipeline Non-Asbestos Gasket - 15MPa Pressure & Oil Resistant, API Compliant For Safe Oil & Gas Transportation
Our industrial-grade asbestos-free sealing sheets (0.5-5mm) are available for immediate procurement through this platform. For optimal performance in sealing applications, we recommend selecting the thinnest viable profile compatible with your operational requirements.
Technical Specifications:
Engineered from thermally bonded aramid fibers and NBR elastomers, these advanced composite sheets demonstrate exceptional resistance to hydrocarbons, aqueous solutions, and natural gas exposures. The cross-linked polymer matrix ensures reliable performance across energy infrastructure applications including turbomachinery seals, pressurized pipeline connections, and marine propulsion systems.
Manufacturing Process:
Precision-formulated using a proprietary blend of:
High-tensile para-aramid reinforcement
Synthetic corrosion-resistant binders
Specialty rubber polymers
Manufactured through precision hot-rolling and vulcanization processes for uniform density.
Performance Grades:
Three thermal classifications (continuous service ratings):
CSNXB150: -50°C to +150°C
CSNXB250: -50°C to +250°C
CSNXB350: -50°C to +350°C
Key Advantages:
► Multi-industry compliance with API 6A/6D specifications
► Delamination-resistant construction with 98% compression recovery
► Cost-effective sealing solution for high-cycle industrial applications
► Independently verified asbestos-free composition (UKAS-certified ISO9001)
► Superior chemical stability against lubricants and refinery streams
Industrial Applications:
• High-pressure flange connections in petrochemical pipelines
• Power generation turbine housings
• Marine diesel engine assemblies
• Hydraulic compressor valve systems
• Fluid transfer infrastructure components
