SPROULE WR-1200®
Sproule WR-1200® is a pre-formed, high temperature, non-wicking pipe and block insulation composed of expanded perlite uniformly reinforced with a high strength fiber for use on systems operating up to 1200°F (649°C). It is inorganic, non-combustible and meets or exceeds the physical property requirements of ASTM C610. Sproule WR-1200 is produced with a blue visual color coding dispersed throughout the product to assure it can be identified as asbestos-free. Integral to Sproule WR-1200 is XOX, a distinctive formula and process that inhibits corrosion to outside surfaces of pipe and equipment, especially stress corrosion cracking of austenitic stainless steel.

THE IIG ADVANTAGE
Specifiers to the industrial processing and power generating industries recognize that stainless steel pipe is susceptible to stress corrosion cracking. IIG's solution is an expanded perlite product with a built-in corrosion inhibitor. Combined with resistance to water absorption, Sproule WR-1200™ perlite effectively minimizes corrosion to outside surfaces of pipe and equipment while providing excellent thermal insulation.
