FIRE RESISTANCE OF EQUIPMENT
LEADING-EDGE APPROACHES

OPK-ZFO structural protection to provide functional resistance of process equipment to fire exposure and to prevent cascade effects.  
Maintenance of workability of the process equipment components, especially emergency and fire protection in case of fire or explosion is the most important part of industrial safety for the hazardous facilities.


SCOPE OF APPLICATION

OPK-ZFO jackets are used to provide functional resistance of valves, control and instrumentation elements, actuation parts of emergency protection etc.
OPK-ZFO flexible fire jackets is the efficient fire protection solution for control systems and provides for significant minimization of risks and damages which may be caused by ignitions at oil refineries, oil platforms, petrochemical plants, thermal power stations, vessels.


REGULATORY FRAMEWORKS

At the moment there are no domestic or foreign regulatory frameworks fully specifying the requirements and values of functional fire resistance of process equipment components.   
Therefore while the requirements for evaluation of functional fire rating of the process equipment are under development, recommends to refer to provisions of the document GAZPROM set of standards (STO GAZPROM) .   

 STO Gazprom 2-1.1-356-2009 Procedural Guidelines to Enhance Resistance of Process Equipment of Gazprom Production Facilities to Fire and Explosion Exposure and to Prevent Cascade Effects:  
 cl. 6.1.4 A term of functional fire resistance of process equipment is introduced by the present standard, which is similar to ensuring safe operation in the event of fire.

cl. 6.1.5. To evaluate the fire rating of process equipment components a value of functional fire resistance is used, designated as F15-F90, where figures after F letter mean time (in minutes) of ensuing safe operation of the process component when exposed to negative factors of fire.  
cl. 5.3.1 Fire ratings of valves, dampers and other components of shut-off and control valves shall be determined according to requirements of ISO 10497:2004 Valves. Requirements for Fire Tests or API 607:2005 Fire Tests for Limited Turn Valves.  

OPK-ZFO flexible fire jackets are produced for operation according to the technical requirements and individual drawings.

OPK-ZFO jackets are delivered in the form of covers ready for prompt installation directly on equipment without any complicated tools used.
