Sproule WR-1200

Sproule WR-1200® Perlite Pipe & Block Insulation

Sproule WR-1200 is a preformed, 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, noncombustible 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.


  • Pipe insulation sections shrink-wrapped with poly film for protection from abrasion during shipment
  • Block insulation manufactured with reinforcing scrim to enhance structural integrity


Because of its compressive strength, low thermal conductivity and corrosion inhibiting properties, it is a product for application on high-temperature piping and equipment. In industrial processing and power generation facilities, Sproule WR-1200 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 XOX feature inhibits corrosion where moisture and chlorides may become trapped between insulation and stainless steel.
