The threaded heating tube, also known as a screw-in heating element, is designed for efficient and reliable heating in a wide range of industrial and commercial applications. Its threaded connection structure allows for easy installation and secure sealing in tanks, pipes, or heating chambers.
Inside the heating tube, electric current passes through a high-resistance Ni-Cr wire, generating heat that is efficiently conducted through high-purity magnesium oxide insulation powder to the metal sheath. The threaded interface ensures tight contact with the heating medium, providing fast heat transfer and stable temperature control.
Constructed from high-grade stainless steel, copper, or Incoloy materials, the threaded heating tube offers excellent resistance to oxidation, corrosion, and high temperatures. It provides long service life, stable operation, and customizable configurations for various heating systems such as water heaters, oil heaters, and industrial tanks.
