Silica Sleeves are primarily used as the thermal protection of circular items, these sleeves can be applied in aerospace (gas turbine and rocket engines), metallurgical, nuclear power, electricity generation, petrochemical industries, etc. for example, tube seals, high temperature gaskets, heaters, reformers, turbine exhaust, boilers, thermocouple wire, etc. Supporting continuous operating temperatures of 2300°F (1260°C) with peak temperatures to 3000°F (1650°C), extremely flexible silica sleeves will resist molten metal splashing, welding splatter, direct flame impact and are resistant to thermal shock. Besides these excellent qualities, Silica Sleeves are highly resistant to corrosion and deterioration caused by chemicals, have good electrical insulation capabilities and remain flexible and drapable at high temperatures.
