The diversity of building scenarios puts forward special requirements for fire doors, such as high-temperature workshops, humid coastal areas, and explosion-proof workshops, conventional fire doors are prone to performance failure and shortened life, so it is necessary to select special fire door products in a targeted manner. The following are the fire door selection schemes and core requirements for three typical special environments.
High-temperature environments (metallurgical workshops, boiler rooms, chemical reactor areas) need to choose high-temperature resistant fire doors. The temperature in such scenarios is maintained above 50°C all year round, and the temperature can rise to more than 1000°C in the event of a fire. The special high-temperature resistant fire door needs to use a high-temperature alloy frame and special fireproof glass, with a built-in ceramic fiber fireproof core material, and the fire resistance temperature can reach 1200°C, and the fire resistance limit ≥ 2.0 hours. The high-temperature fire door of the pilot door industry is also equipped with a heat dissipation structure design to reduce the damage of high temperature to the door body, and has been used in many domestic steel plants and chemical plant projects, passing the rigorous high temperature environment test.
Wet environments (coastal areas, underground garages, aquatic product processing plants) need to focus on corrosion resistance. High humidity and high salt spray environment are easy to lead to rust of steel doors and mildew of wooden doors, so it is necessary to choose 304/316 stainless steel or anti-corrosion treatment steel fire doors, the surface is drawn, spraying and other processes to enhance the anti-corrosion ability, the hardware accessories are made of stainless steel, and the sealing rubber strip is made of silicone rubber material that is moisture-resistant and not easy to age. Pilot Door Industry's customized stainless steel fire doors for coastal areas in Southeast Asia have passed a 72-hour salt spray test and have met the corrosion resistance standard, and have been successfully applied to a port warehouse project in Malaysia.
Explosion-proof fire doors should be selected in explosion-proof environments (dangerous goods warehouses, petrochemical workshops, gas stations). Such scenarios need to take into account both fire and explosion-proof functions, and the door body needs to be made of high-strength explosion-proof steel plates, which have the ability to resist shock waves, and the built-in fireproof core materials meet the requirements of fire resistance. The door body opening method adopts an explosion relief design, which can automatically relieve pressure under the action of explosion pressure to avoid secondary damage caused by door body crushing and splashing. The product must pass the national explosion-proof certification to ensure that it can still play a fire separation role in the explosion scene. The explosion-proof fire door of the pilot door industry adopts thickened steel plate and reinforcement structure design, and the shock wave pressure is up to 0.15MPa, which has passed the relevant explosion-proof certification and is suitable for various dangerous goods storage and production sites.
In addition to meeting the core performance requirements, special environment fire doors also need to ensure certification compliance, such as high-temperature fire doors need to pass high-temperature resistance testing, explosion-proof doors need to have explosion-proof certification, and cross-border projects need to meet the special environmental standards of the target market. Pilot Door Industry can provide customized solutions according to the scene temperature, humidity, medium and other parameters, from material selection, structural design to certification to ensure that the product is suitable for special environmental needs.
