Explosion-proof doors to resist accidental industrial building outside of the device, and ensure the safety of personnel and industrial equipment inside the building in good condition, free from blast damage; effectively prevent the continuation of an explosion hazard. The use of special steel industry in accordance with strict mechanical data set production, and with high-performance hardware accessories, to use more practical and beautiful. Protection of life and property safety. Blast doors also known as: the doors. [1], in the case of an explosion, did not meet pre-set explosive, explosion-proof doors can still be used normally. [2], in the event of an explosion, according to the notice of the explosion pressure and the set of the incident reflected power. Explosion-proof doors can withstand blast pressure range within the species, but to achieve the necessary protection against casualties and property losses. [3], when the explosion occurred, the explosive force reaches the preset can be deformed, but still maintain the use of the components of the door, to avoid personnel are retained, blocking the storm. [4], the necessary sealed isolation, and prevent the direct isolation of space and the outside air convection, was cut off in order to reduce the space protected by external contamination. [5], proof door is a safe facility, with autistic features and emergency escape capabilities. [6], anti-shock-proof door is common: 0.021Mpa = 21Kpa, 0.045Mpa = 45Kpa, 0.069Mpa = 69Kpa.
