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(650°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 , a distinctive formula and process that inhibits corrosion to outside surfaces of pipe and equipment.
Because of its compressive strength, low thermal conductivity and corrosion inhibiting properties, Sproule WR-1200° Perlite insulation is an excellent product for application on high temperature piping and equipment. In industrial processing and power generation facilities, Sproule WR-1200® Perlite insulation is the preferred product for stainless steel piping, which is very susceptible to stress corrosion cracking at operating temperatures above 140°F (60°C). The feature inhibits corrosion where moisture and chlorides may become trapped between insulation and stainless steel.
- Pipe insulation sections shrink-wrapped with poly film for protection from abrasion during shipment
- Block insulation manufactured with reinforcing scrim beneath the outside surface enhancing structural integrity
