Thermo-12® Gold/24

Pipe & Block Insulation

Description

Thermo-12® Gold is a moulded, high temperature, abuse-resistant pipe and block insulation with exceptional structural strength, composed of hydrous calcium silicate for use on systems operating up to 1200°F (649°C). The gold colour provides positive identification that it is asbestos-free. Thermo-12® Gold/24 meets or exceeds the physical property requirements of ASTMC533, Type 1. Integral to Thermo-12® Gold/24 is XOX, a distinctive formula and process that inhibits corrosion to outside surfaces of pipe and equipment.

Advantages

  • Guards pipe and equipment surfaces against corrosion;
  • Excellent resistance to breakage and physical abuse;
  • No binders to burn out = No loss of insulation integrity;
  • Superior thermal performance from 450°F to 1200°F (650°C);
  • Resistant to mould growth;
  • Fast, easy installation;
  • Large selection of sizes and forms

Applications

Thermo-12® Gold/24 is especially recommended for use in the petrochemical, power generation and process industries where piping and equipment operating up to 1200°F (649°C). Its strength, low thermal conductivity, and durability makes it the preferred product for application on high temperature piping and equipment. The XOX corrosion inhibiting properties are not diminished by heating and cooling so the corrosion protection will continue for the life of the product. Thermo-12® Gold/24 will not burn and may be used for fire protection in some applications.
