Refractory Systems
These insulation systems are designed to withstand extremely high temperatures that would destroy normal insulation.
What are refractory insulation systems?
This cement-like refractory material is mixed with water and poured or trowelled into forms.
What is castable refractory?
Reflective insulation reduces this type of heat transfer by reflecting heat back toward the source.
What is radiant heat?
These coatings are applied to the inside surface of insulation such as cellular glass to protect against abrasion.
What are bore coatings?
These coverings protect insulation on pipes, fittings, ducts, and equipment.
What are jackets?
Refractory installations typically operate above this temperature.
What is 1500°F (815°C)?
This material bonds refractory bricks and seals joints.
What is refractory mortar?
This reflective material is used because it maintains strength at high temperatures and resists corrosion.
What is stainless steel reflective material?
This type of bore coating provides a tough protective finish.
What is an anti-abrasive coating?
Name two common metal jacketing materials used for insulation protection.
What are aluminum, stainless steel, or galvanized steel?
Name two pieces of industrial equipment that commonly use refractory insulation.
What are furnaces, boilers, kilns, dryers, incinerators, or high-temperature piping?
These cements are used to repair refractory surfaces, bond insulation materials, or seal systems.
What are high-temperature cements?
These reflective materials are woven fabrics made from alumina-silica fibers.
What are reflective fabrics?
This heavy-bodied mastic protects the bore by providing a soft cushion between insulation and the substrate.
What is bedding compound?
These supports distribute pipe weight so insulation is not crushed by hangers.
What are saddles?
These gaps are intentionally left between refractory sections to allow movement when materials expand or contract.
What are expansion joints?
This rigid high-temperature insulation is commonly used on piping and boilers.
What is calcium silicate?
Reflective fabrics are often used to make these removable protective coverings for irregular surfaces.
What are removable insulation blankets?
This adhesive seals insulation joints and can seal breaks in vapor-barrier jacketing.
What is contact adhesive?
These protective pieces may be installed where insulated pipes pass through walls.
What are sleeves?
Without these, refractory systems can crack, bulge, or fail.
What are expansion joints?
This lightweight insulation made from alumina-silica fibers can withstand temperatures up to about 3200°F.
What is ceramic fiber?
Reflective fabrics are often coated with this reflective metal powder.
What is aluminum powder?
These paste-like materials provide protective finishes and seal breaks in jacketing.
What are mastics?
This plastic film is used to protect underground cellular foam pipe insulation.
What is polyethylene film?
