» Industrial » Perlite Insulation Pipe and Block
Specifiers to the industrial processing and power generating industries recognize that stainless steel piping is highly susceptible to stress corrosion cracking at temperatures over 140°F. IIG’s intelligent insulation solution is an expanded perlite product with a binder of sodium silicate - an excellent corrosion inhibitor. Combined with a resistance to water absorption, Sproule WR-1200™ perlite effectively minimizes corrosion while providing excellent thermal insulation.

| Sproule WR-1200 is a molded, high-temperature pipe and block insulation with exceptional corrosion inhibiting properties. For use on systems operating up to 1200°F (649°C), it is composed of expanded perlite, uniformly reinforced with a high-strength fiber, and with a binder that contains sodium silicate, long recognized as an excellent corrosion inhibitor. Sproule WR-1200 is produced with a blue visual color coding dispersed throughout the product to assure it can be identified as asbestos-free. It meets or exceeds the physical property requirements of ASTM C 610. |
