Jiangsu Plaza Premium Electric Instrument Co.,Ltd.(HY)
Product description
For tubular heating elements, the typical electrical termination is a ceramic insulator with a threaded stud terminal. Flexible lead wire extensions or other mounting options are available for specific applications.
Standard tube diameters are 8mm 10mm 12mm 16mm, but other special sizes are available for electric tubular heating element. Depending on the diameter, lengths can be supplied up to 6000mm. Standard sheath materials are Stainless Steel 201, 304, 316 and 321, but special sheath materials may be available based on diameter and size of the element required.
