Typical Applications
Oil & Gas Industry
Designed to protect bolted flange connections in refineries, petrochemical plants and gas processing units, reducing the risk of bolt failure under hydrocarbon fire exposure.
Offshore Platforms & FPSO
Widely applied on offshore installations, including FPSOs and drilling platforms, where critical bolted joints require reliable fire protection in harsh marine environments.
Pipeline and Valve Assemblies
Installed on pipeline flanges and valve connections to maintain mechanical integrity during fire scenarios, ensuring continued operation or safe shutdown.
LNG & Gas Handling
Suitable for LNG terminals and gas distribution systems, where flange protection is essential to prevent leakage caused by thermal stress or fire exposure.
Chemical & Process Industries
Used in chemical plants and industrial processing facilities to protect critical bolted joints from fire hazards and extreme temperatures.
FAQs about fire rated bolt caps?
1、Can bolt caps be customised for different flange sizes?
Yes, bolt caps can be manufactured to suit a wide range of flange types, bolt configurations and project-specific requirements.
2、What fire standards can bolt caps be designed to meet?
Bolt caps can be engineered to comply with recognised fire protection standards, including hydrocarbon fire curves and jet fire resistance requirements, depending on project specifications.
3、How do bolt caps prevent flange leakage during a fire?
By reducing the rate of heat transfer to bolts and studs, bolt caps help maintain bolt tension and sealing pressure, lowering the risk of flange failure and leakage under fire conditions.
