Stainless Steel Flanges, U-shaped Heating Tubes

are components used to connect pipes to each other, attached at the pipe ends. Flanges have holes, and bolts are used to tightly join two flanges together.

Stainless Steel Flanges, U-shaped Heating Tubes are sealed with gaskets between flanges. High-temperature resistance wires are evenly distributed inside high-temperature resistant stainless steel seamless tubes, and the gaps are densely filled with crystalline magnesium oxide powder that has good thermal conductivity and insulation properties. This structure is not only advanced and highly efficient in heat transfer, but also provides uniform heating. When current passes through the high-temperature resistance wires, the generated heat diffuses through the crystalline magnesium oxide powder to the metal tube surface, and then transfers to the heated object or water, achieving the purpose of heating.

 
Steel electric heating tubes use high-quality domestic thick-walled seamless stainless steel tubes, imported low-temperature magnesium oxide powder from the United States, and sealing materials, allowing the heating tubes to withstand temperatures up to 900°C. Under temporary dehydration conditions, the heating tubes 

are made by placing electric heating wires inside seamless metal tubes (carbon steel tubes, titanium tubes, stainless steel tubes, copper tubes), and tightly filling the gaps with crystalline magnesium oxide that has good thermal conductivity and insulation properties. The two ends of the heating wire are connected to the power supply through two lead-out rods. After filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation properties, the tube is reduced in diameter. Because the heating tube is bent into a shape resembling the English letter U, it is called a U-shaped heating tube.
