Explosion proof door is a kind of anti explosion protection equipment to resist the accidental explosion of devices outside the industrial building, ensure the safety of personnel and the integrity of internal equipment of the industrial building, avoid the damage of blasting shock wave, and effectively prevent the continuation of blasting damage. It can be made of special industrial steel plate according to the mechanical data set strictly, and equipped with high-performance hardware accessories to ensure the safety of life and property.
How to distinguish true and false explosion-proof doors:
1、 Check whether the fire and explosion-proof door has a certificate and inspection statement. The certificate is the product type approval certificate issued by the fire product qualification appraisal center of the Ministry of public security. Whether the inspection statement is issued by the quality supervision and inspection center of fixed rescue explosion-proof system and refractory components or the quality supervision and inspection center of fireproof building materials.
2、 See if the fireproof and explosion-proof door is pasted with red identification (the center is a large black "s").
3、 See whether the fire and explosion-proof door has a product brand. The name of the manufacturer on the brand should be common with the certificate and inspection statement. The product name should clearly indicate that it is a fire door product.

The fire prevention experts of the fire brigade suggest that the quality of fire and explosion-proof doors is of course important, and the installation quality can not be ignored: for example, the movable gap between the door leaf and the lower frame of the door or the ground can not be too large. If it exceeds 9 mm, it will affect the smoke and fire prevention function of the fire door. As for the steel door frame, cement mortar shall be poured in the door frame. Knock on the door frame and listen to the sound to know whether the cement slurry is filled.
Function of explosion-proof door:
The function of explosion-proof door is to resist the blasting conditions in industrial buildings. Explosion-proof door is a kind of equipment to ensure personal safety and the internal structure of industrial buildings.
