FLAT TUBULAR ELEMENTS

Standard or customized types, straight or bended

DESCRIPTION

Elektrotermija offers highly compressed tubular heating elements made of stainless steels, with flat oval cross section. They can be delivered in straight design or bended as to specification, with various connection types or with brazed mounting bushes. There is a possibility to produce of element with connection at one or two ends or locating the thermocouple inside the rod. Standard elements are available from stock. Additionally, various sheath materials are possible. Flat tubular elements are recommended for use in a wide range of industrial applications even in the harshest operating conditions.
