Calcium Silicate Pipe Covering

Calcium Silicate Pipe Covering

Thermo-12 Gold is pre-formed, high-temperature, abuse-resistant calcium silicate pipe insulation and block insulation. It has exceptional structural strength, and can be used on operating systems that reach 1200°F (650°C). Thermo-12 Gold is composed of hydrous calcium silicate and is made with XOX, a proprietary formula and process that inhibits corrosion to the outside surfaces of pipe and equipment. Calcium silicate insulation is inorganic, noncombustible, asbestos-free and meets or exceeds the physical and thermal property requirements of ASTM C533, Type 1.

Product Description

Calcium silicate (CalSil) is used to insulate high-temperature pipes and equipment and for fire endurance applications. It is manufactured and sold in three different forms: preformed block, preformed pipe, and board. Today’s calcium silicate manufactured in North America is noted for its high compressive strength, corrosion-inhibiting properties, and high-temperature structural integrity. It can withstand continuous temperatures up to either 1,200°F (Type I, for pipe and block) or 1,700°F (Type II, fire endurance boards).

Common Applications
Calcium silicate insulation is typically applied on high-temperature (greater than 250°F) pipe and equipment in industrial facilities, such as chemical plants, refineries, and steam electric power plants. Since it is a rigid material that has a relatively flat thermal conductivity curve, extremely high compressive strength, high flexural strength, a Class A rating for Flame Spread/Smoke Developed, and is noncombustible (ASTM E136), it is widely used in high-temperature, industrial applications subject to physical abuse.

Due to its high compressive strength (greater than 100 psi), high flexural strength (greater than 50 psi), and resistance to damage from tumbling, plus its ability to maintain those properties over time up to its rated 1,200°F, calcium silicate can withstand considerable physical abuse without loss of insulating efficiency. In addition, calcium silicate insulation can withstand vibration induced by high-temperature steam flow around internal pipe obstructions, such as valve internals, measuring devices, and flow restriction orifices.”
