Distribution International supplies calcium silicate insulation (sometimes referred to as “CalSil”) designed for high-temperature piping, equipment, and fire endurance applications. Known for its structural strength and thermal stability, this material delivers long-term performance in some of the most demanding industrial environments.
Overall Performance: Calcium silicate insulation offers exceptional high-temperature structural integrity and compressive strength. It also provides effective corrosion inhibition, helping extend the life of underlying systems in harsh environments.
Physical Characteristics: This material is inorganic, non-combustible, asbestos-free, and designed to resist corrosion under insulation (CUI) for both carbon and stainless steel. It meets or exceeds the requirements of ASTM C533, Type I.
Temperature Range: Calcium silicate can handle temperatures typically ranging 250°F to 1,200°F/650°C (Type I, for pipe and block) or 1,700°F/927°C (Type II, fire endurance boards).
Environmentally Safe & Friendly: Calsil is asbestos-free and landfill disposable, offering a safe and sustainable option for industrial systems
Damage Tolerant: Calcium silicate has superior resistance to physical damage, calcium silicate withstands jobsite handling, installation stress, and other impacts without compromising performance.
Fabricated Products: Calcium silicate can be delivered in block, standard pipe cover, curved segments, fittings, and tank heads in sizes to match your job requirements. DI fabricates pipe cover to comply with ASTM C585 and fittings to ASTM C450. Utilizing the best-in-industry manufacturing techniques, DI ensures products are fabricated to exact standards, delivering products that fit the first time, every time.
Reduced Labor Cost: DI fabricated products eliminate in-field fabrication time and cost, allowing you to focus on installation.
