Tubular Heating Elements
Tubular heating elements are designed for use in either radiant heating or contact surface heating. A very common type of heating elements, tubular heating elements can be bent in standard or custom shapes to fit a particular application. Tubular heaters are divided into two main categories: single-ended and double-ended. Single-ended tubular heaters have two terminals at one end while double-ended tubular heaters have one terminal on both ends.
In order to ensure optimal performance, tubular heating elements sometimes are housed within a casing or other protective component. This protective covering is usually made of sleeve or sheath. Copper, aluminum, brass, nickel alloy, iron, rubber, synthetic rubber, steel, stainless steel, and polyimide are common options used to construct the covering.
There are multiple options when selecting tubular heaters. Cryogenic use, level of corrosion resistance, dynamic power regulation capabilities, and portability are important aspects of tubular heating elements. The heaters can also be explosion-proof or finned. Many also offer independent timing controls, overheat protection, internal temperature detectors, and other additional features.
