Introduction of explosion-proof wall

Explosion-proof wall: a wall composed of metal structure, which has the ability to resist explosion shock wave and can limit the destructive effect of explosion to a certain range. Compared with the reinforced concrete explosion-proof wall, it has the advantages of being heavy and light, easy to disassemble and assemble, recyclable and so on.

1. material: non-combustible material with explosion-proof capability.

2. Scope of application: applicable to petroleum, chemical industry, nuclear power, military industry, offshore oil platforms, power transformer rooms, warehouses, etc.

A workshop for storing flammable and explosive materials in buildings that need to be isolated.

3. Materials and structures

(1) The explosion-proof wall consists of steel keel (galvanized square pipe 100*50*3mm), fiber cement composite steel plate (explosion-proof plate) and rock wool. The thickness of explosion-proof wall is 120mm.

(2) Fiber-cement composite steel plate (explosion-proof plate) is a synthetic fire-proof plate formed by pressing perforated galvanized steel plates with a thickness of 0.5m from top to bottom on fiber cement with a thickness of 8.5m. The fiber cement layer sandwiched between the two steel plates can absorb energy.

(3) The specification of fiber cement composite steel plate (explosion-proof plate) is1200 * 2400 * 9.5m. It can be cut according to actual needs.

4. Key point selection

(1) Explosion-proof walls are divided into non-thermal insulation type and thermal insulation type. The thermal insulation type is to make fiber cement steel plates inside and outside the metal skeleton, and the middle of the skeleton is filled with rock wool. The fire resistance limit of thermal insulation explosion-proof wall can reach 4h.

(2) The pressure value of explosion-proof wall is ≥400KPa, and what our company does can be above 1000KPa. (i.e. 1MPa).
