ContraFlex® jet fire protection jackets can provide hydrocarbon jet fire protection for up to 180 minutes in line with ISO 22899-1:2009, what’s more with a flexible insulation and protection system- can be easily removed for equipment maintenance.

ContraFlex® jet fire resistant jackets can provide jet fire protection up to 180 minutes (J180) in line with ISO 22899-1:2009 “Determination of the Resistance to Jet Fires of Passive Fire Materials, Part One: General Requirements” and to the guidance criteria of the Health and Safety Executive, Offshore Technology Report OTI 95 634 “Jet Fire Resistance Test of Passive Fire Protection Materials”. Jet fires pose the most onerous threat in the field with elevated temperatures of 1,350°C for up to three hours.

ContraFlex® jet fire resistant jackets have been tested for tubular, planar and corner/edge features and have been approved by ABS, Lloyd’s Register and DNV. The extensive range of testing means that ContraFlex® may be used on piping, flanges, ESDV valves and actuators, vessels, heat exchangers, pipe supports and control panels.

Construction:

  • Outer Cloth: Flame retardant, alkali free silicone polymer coated material.
  • Jacket Thickness Jet fire PFP Jackets range from 36mm to 120mm. The jacket infill depends on the fire scenario and can be built up from a mixture of insulation, jet fire resistant materials and SS304 mesh.
  • Inner Cloth: Flame retardant, alkali free silicone polymer coated material.

Features:

  • Third party certification and inspection: ContraFlex® jet fire jackets hold Lloyd’s Register, ABS and DNV certification
  • Low maintenance and inspection time: ContraFlex® jackets can be safely and easily removed for ease of maintenance to the equipment and therefore keep downtime to a minimum. Furthermore, PFP jackets can be removed and refitted by maintenance personnel directly, excluding the requirement for specialist sub-contractors
  • Low installation time: ContraFlex® jackets are flexible and therefore easier to handle and install in relation to conventional cladding and enclosure type systems, therefore reducing installation time
ContraFlex jacket cross section example

ContraFlex jacket cross section example

ContraFlex® jet fire PFP Jackets have been tested to the following fire scenarios:

  • J45 – Jacket minimum thickness 35mm – minimum weight per m2 9.4kg/m2
  • J60 – Jacket minimum thickness 61mm – minimum weight per m2 13.1kg/m2
  • J120 – Jacket minimum thickness 61mm – minimum weight per m2 13.1kg/m2
  • J180 – Jacket minimum thickness 75mm – minimum weight per m2 13.9kg/m2

Jacket thickness is subject to change based on the section factor (Hp/A or A/V) for piping.

Individual material layers have been tested for Combustibility, Flammability and Toxicity in accordance with IMO MSC 307(88) Appendix 1, Part 1, 2 and 5.
