Sproule WR-1200® is a pre-formed, high-temperature, non-wicking pipe and block insulation. It is composed of expanded perlite that is uniformly reinforced with a high-strength fiber for use on systems operating up to 1200°F (649°C). Sproule WR-1200 is inorganic, non-combustible and meets or exceeds the physical property requirements of ASTM C610. It is produced with XOX Corrosion Inhibitor®, a distinctive formula that inhibits corrosion to outside surfaces of pipe and equipment, especially stress corrosion cracking of austenitic stainless steel.
