Titanium threaded tube (low fin tube) is rolled from a seamless titanium tube. Its threaded low fins are integrated with the titanium tube. It has no contact thermal resistance, high strength, pressure resistance, thermal shock resistance and mechanical resistance. Vibration, so it has better mechanical heat transfer and thermal expansion properties. The effects of increased heat transfer coefficient and reduced scaling of finished titanium tubes after rolling. However, the pressure drop increases slightly, while the flow area outside the tube increases. Tests have shown that when the heat transfer coefficient inside the tube is more than 2 times greater than that outside the tube, the heat transfer coefficient can be increased by 20% to 30%.

Titanium threaded tube (low fin tube) adopts industrial pure titanium tube TA1TA2. The base tube has excellent ductility and corrosion resistance. The titanium tube has strong corrosion resistance. This is because it has a particularly large affinity for oxygen and can generate a chemical on its surface. A dense oxide film protects the titanium tube from medium corrosion. Therefore, titanium has good stability in acidic, alkaline, neutral salt water solutions and oxidizing media. It has better corrosion resistance than existing stainless steel and other non-ferrous metals, and has excellent performance in comprehensive applications.

Titanium threaded tube (low fin tube) Among the many high-efficiency heat transfer elements that have been successfully developed, titanium threaded tube low fin tube has been promoted in industrial equipment and achieved good results.

Titanium tube Titanium alloy tube is based on the GB/T 3625-2007 standard and has high pressure bearing and strong corrosion resistance. The integrally rolled titanium threaded finned tube passes through, which increases the heat transfer area between the fluid and the wall surface and improves the total heat transfer of the tube. It increases the degree of fluid turbulence and improves the contact efficiency between the fluid and the wall. Destroy the development of the fluid thermal boundary layer, enhance the heat transfer capacity of the heat exchange tube and reduce the resistance of steam molecules to diffuse to the liquid film surface. Thin the liquid film thickness, increase the heat exchange area, and at the same time increase the contact time between the fluid and the wall within a certain range, which can effectively enhance the heat transfer effect.
