Functions and application scenarios of explosion-proof walls

Thread Content

I. The primary function of blast walls: A blast wall (explosion-resistant wall) is a specialized protective structure designed to withstand the effects of explosion shock waves, high temperatures, and debris. • Blast resistance: Withstands explosion overpressures of 0.1–3 MPa, preventing shock waves from penetrating. • Fragment containment: Walls do not splatter or produce high-speed dangerous fragments. • Partition protection: Maintains fire, smoke, and gas diffusion prevention even after an explosion. • Structural stability: It shares the load with the main structure, preventing collapse caused by local failures. • Risk containment scope: Limit explosive damage to a localized area, protecting personnel and critical equipment. II. Typical application scenarios
1️⃣ Industrial high-risk scenarios
• Chemical/Petroleum: Reactor areas, storage tank areas, oil and gas processing plants, control rooms. • New energy: Lithium battery workshop (filling/formation), hydrogen storage/electrolyzer area. • Dust explosion prevention: grain processing, plastic crushing, and metallurgical coal injection workshops. • Pharmaceuticals/Specialty Chemicals: Solvent synthesis, hazardous materials production sections. 2️⃣ Warehousing and energy facilities • Hazardous materials storage: areas for storing explosives, chemicals, gasoline, and liquefied gas tanks. • Oil/gas stations: oil storage tanks, gas filling stations, gas boiler rooms. • Electric power/nuclear power: substations, nuclear island safety areas, fuel buildings. 3️⃣ Military and security • Ammunition depots, explosives workshops, military bases, test sites. • Anti-terror positions, border checkpoints, important shelters. 4️⃣ Public and civilian • Laboratories/hospitals: Hazardous materials testing areas, oxygen cylinder storage rooms. • Transportation hubs: subways, airports, and storage sites for hazardous materials at ports.
