1. Perlite Filling (Discharge/Filling) Work
Perlite rock is as the thermal insulating material of filling in low-temperature powder insulated storage tank interlayer, the features such as apparent density is light, coefficient of thermal conductivity is low owing to having, chemical inertness is good, serviceability temperature scope is wide, nonpoisonous and tasteless, are thus widely used in the device such as ice chest for air separation equipment, cryogenic liquid vessel.
2. Perlite Concrete Blocks Work
Perlite Concrete Blocks (PCBs) are engineered, lightweight, thermal insulating, reinforced, and waterproofed concrete blocks useful for, among other things, forming a bottom ring beam at the double-wall of cryogenic storage tanks. ey provide excellent thermal insulation at negative temperatures and structural support against static and dynamic loads. PCBs are manufactured from a mix of Construction Grade expanded perlite aggregate, Portland cement, and admixtures. ey are reinforced with steel or stainless-steel bars and lifting hooks and are manufactured under stringent quality standards to achieve consistent technical properties of compressive strength, thermal conductivity, density, and dimensional tolerances.
3. Fireproofing/Firestop Work
Fireproofing, a passive fire protection measure, refers to the act of making materials or structures more resistant to fire, or to those materials themselves, or the act of applying such materials. Applying a certification listed fireproofing system to certain structures allows these to have a fire-resistance rating.
Fire stopping, also known as compartmentation, is a fundamental part of passive fireproofing. It refers to the process of filling openings and joints between walls and floors with fire-resistant material, inhibiting the spread of fire between 'compartments' within a building.
