Flexible joints

Advanced Insulation’s ContraFlame® C20 Silicone Flexible Joint provides integrated insulation and passive fire protection (PFP) capable of withstanding harsh offshore weather conditions whilst providing acoustic, blast, thermal and fire protection.

The system is based on a unique syntactic silicone, pre-moulded into a U-shaped joint which is bolted between modules, allowing the required movement between the modules but also providing integral fire protection to offshore facilities. This system provides flexibility where rigid type PFP systems are not suitable. Advanced Insulation have been providing silicone-based subsea insulation for over 10 years which has led to the research and development of innovative silicone based PFP.
