Every minute counts when a structure catches fire. As soon as the steel reaches the critical core temperature of around 550°C, the structure threatens to collapse. Passive fire protection has consequently become an absolute must. In line with these requirements, WIWA has further developed its application systems for flameproofing materials further.
WIWA tried and tested systems can be used even under the toughest conditions – and the WIWA DUOMIX PFP 333 Zone 1 version is now certified for the offshore industry. Flame proofing materials are applied directly to the structural elements, such as steel girders, pipelines or steel containers. In case of fire, the material foams to increase the distance between the fire and the structural element, delaying the temperature increase of the steel.
This buys rescue and evacuation teams valuable time.
Strong pumps required
Intumescent fire protection materials with high viscosity and a high solids content can only be processed and applied efficiently with especially powerful systems – and depending on the place of use they may have to resist the toughest of conditions. "Fire protection work in the offshore area or on oil rigs is an enormous challenge through wind and water alone", Johannes Jacobi, Head of Marketing at WIWA, explains. "We have therefore made crucial further developments on our dual component application systems for passive fire protection in close cooperation with leading material manufacturers."
Lloyd's Register EMEA has tested this system and the result was: WIWA DUOMIX PFP 333 Zone 1 is one of the first dual component fire protection systems to be certified for the offshore industry.
High-build coatings, high coverage
WIWA DUOMIX PFP 333 Zone 1 is based on the successful WIWA DUOMIX PFP 333, with electronic components reduced to a minimum. All system components comply with the ATEX guidelines. Thanks to the powerful extrusion pumps, the WIWA DUOMIX PFP 333 allows the application of thick coats with an output to cover up to 500 square metres per day. WIWA have also developed a spray gun especially for fire protection materials, with nozzles of different sizes and spraying angles available.
