Thermal insulation blankets are used to cover the heating elements on a heat treatment set up, to help ensure the desired temperature is reached, reduce heat losses away from the edge of the heaters, and provide personnel protection.
These insulation blankets are supplied wrapped in stainless steel mesh which improves reusability of the insulation.
28 kg/m³ density insulation, though costing a little more, has better insulation properties than 96 kg/m³ insulation.
This 600mm wide x 600mm long blanket is normally used for pipe welds up to 150mm (6”) diameter, as a single blanket or larger diameters when used with additional blankets.
Superwool is a high temperature insulating fibre blanket manufactured from Calcium Magnesium Silicate. This material has a thermal performance equivalent to refractory ceramic fibre up to 1200ºC. However, unlike ceramic fibre, Superwool is body soluble and has a larger needle particle size. These qualities mean that Superwool represents a lower respiratory hazard than ceramic fibre, although, as with all high temperature insulating fibre, normal respiratory protection in the form of an appropriate dust mask should be worn during handling.
