Passive fire protection (PFP) is a critical safety measure for protecting critical equipment in a variety of industries, including oil and gas, petrochemical, and power generation. PFP systems work by preventing the heat from a fire from reaching the equipment that they are protecting. This is done by using a combination of materials that are resistant to heat and fire. There are various types of fire ratings for protection, such as jet fires or hydrocarbon pool fires, with different durations of protection.

There are two main types of PFP systems: Flexible and Rigid.

Flexible PFP systems are made of materials like fiberglass, mineral wool, or foam. They are typically used in applications where there are tight spaces or where the PFP system needs to be able to move. Flexible PFP systems are easy to install, low in cost, and can be cut to fit any shape. However, they are less durable than rigid systems.

Rigid PFP systems are made of materials such as expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR). They are typically used in applications where there is a need for high thermal performance. Rigid PFP systems are more durable than flexible PFP systems, but they are also more challenging to install.

Here is a table that summarizes the pros and cons of flexible and rigid PFP systems:

Which type of PFP system is right for you?

The best kind of PFP system for you will depend on your specific needs. If you are looking for a PFP system that is easy to install and maintain, flexible PFP systems are a good option. An example of a flexible PFP system is our Ancloz Armourflex flexible removable PFP Jacketing, which can be applied to installations like Floating Production Storage and Offloading (FPSO) vessels that regularly use them. If you need a highly durable PFP system to prevent heat transfer, rigid PFP systems are a better choice, such as rigid box systems that are made up of the PFP material encased in metal.

Here are some additional factors to consider when choosing between flexible and rigid PFP systems:

• The type of equipment you are protecting
• The type of fire that you are most concerned about (Jetfire or Poolfire)
• The budget you have available
• The duration of protection

Conclusion

Flexible and rigid PFP systems are both effective ways to protect critical equipment from fire. The best type of PFP system for you will depend on your specific needs and budget.
