Sleeve (Sheath) Material
|
|
Most heaters have a protective sheath or sleeve that covers the heating elements. There are usually many choices for sheath or sleeve material.
|
| |
Your choices are...
|
|
|
| |
None
|
|
The heater has a bare, exposed heating element without a sleeve or sheath.
|
| |
Aluminum
|
|
The sleeve or sheath is made of aluminum, a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that provides good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
|
| |
Brass
|
|
The sleeve or sheath is made of brass, an alloy that provides good strength, excellent high temperature ductility, reasonable cold ductility, good electrical conductivity, excellent corrosion resistance, and low magnetic permeability.
|
| |
Copper
|
|
The sleeve or sheath is made of copper, a common, reddish, metallic element that is ductile and malleable. Copper is one of the best conductors of heat and electricity.
|
| |
Fluoropolymer (Teflon®)
|
|
The sleeve or sheath is made of a fluropolymer such as Teflon® (DuPont Dow Elastomers). Teflon refers to a class of fluoropolymer resins used for a wide variety of commercial applications. They are highly-resistant to temperature, chemical reaction, corrosion, and stress-cracking.
|
| |
HT Foil (Ceramic Foil)
|
|
The sleeve or sheath is made of high temperature (HT) foil. HT foil is sometimes called ceramic foil.
|
| |
Iron
|
|

|
| |
Stainless Steel
|
|
The sleeve or sheath is made of stainless steel, a chemical and corrosion resistant alloy that can have relatively high-pressure ratings.
|
| |
Steel
|
|
The sleeve or sheath is made of steel, a commercial iron that contains carbon in any amount up to about 1.7% as an essential alloying constituent. Steel is malleable under suitable conditions and distinguished from cast iron by its malleability and lower carbon content.
|
| |
Synthetic Rubber (Neoprene)
|
|
The sleeve or sheath is made of a synthetic rubber such as neoprene.
|
| |
