Insulation/Isolating Gaskets and Flange Isolation Kits

Anchor Building Materials Trading LLC provides premium Isolation Kit Gaskets engineered to deliver exceptional sealing, electrical isolation, and corrosion protection in demanding industrial environments. These gasket kits ensure safe, efficient, and long‑lasting pipeline performance across oil & gas, petrochemical, marine, water, and industrial applications.

Applications
Isolation Kit Gaskets are ideal for:
• Oil & gas pipelines (upstream, midstream, downstream)
• Petrochemical and refinery plants
• Water and wastewater treatment systems
• Marine and offshore installations
• District cooling and HVAC systems
• Industrial processing facilities
• Cathodic protection systems
• Chemical and fertilizer industries
They are essential wherever electrical isolation, corrosion control, and high‑integrity sealing are required.

General Features
• Provides electrical isolation between flanges
• Prevents galvanic corrosion and metal deterioration
• Ensures leak‑free sealing under high pressure
• Resistant to chemicals, hydrocarbons, and moisture
• Suitable for high‑temperature and high‑pressure environments
• Compatible with RF, FF, and RTJ flange faces
• Long service life with minimal maintenance
• Easy installation with standard tools
• Available in multiple materials and thicknesses

Types of Isolation Kit Gaskets
1. Full‑Face Isolation Gasket (FF)
• Covers the entire flange face
• Ideal for low‑pressure water and utility systems
2. Ring Type Isolation Gasket (RT)
• Fits inside the bolt circle
• Suitable for high‑pressure oilfield and industrial applications
3. RTJ Isolation Gasket
• Designed for Ring Type Joint flanges
• Used in high‑pressure, high‑temperature pipelines
4. High‑Temperature Isolation Kits
• Made from G‑10, G‑11, or PTFE
• Suitable for extreme temperature environments
5. Fire‑Safe Isolation Kits
• Maintains sealing integrity during fire exposure

Specifications

• Temperature Range: –50°C to +200°C (material‑dependent)
• Dielectric Strength: High electrical resistance for isolation
• Flange Compatibility: ASME, DIN, API, BS standards
• Thickness Options: 1.5 mm – 6 mm
• Kit Includes:
• Isolation gasket (FF or RT)
• Insulating sleeves
• Insulating washers
• Steel washers

Materials
Available in:
• Phenolic resin
• Neoprene‑faced phenolic
• EPDM
• PTFE (Teflon)
• G‑10 / G‑11 glass epoxy
• Nitrile rubber (NBR)
• Mica / graphite composites (fire‑safe)
Material selection depends on fluid type, temperature, pressure, and corrosion risk.

Suggestions & Recommendations
• Use PTFE for aggressive chemicals and corrosive fluids
• Choose G‑11 for high‑temperature applications
• Select full‑face gaskets for water systems to prevent flange distortion
• Use ring type gaskets for oilfield and high‑pressure pipelines
• Replace sleeves and washers whenever installing a new kit
• Ensure flange faces are clean, aligned, and free from debris
• For cathodic protection systems, choose high‑dielectric materials
