Features of Titanium Welding Tube

1. High degree of automation, high production efficiency. Titanium welded pipe is the selection of high quality titanium strip, in the automatic pipe welding production line, after heat treatment, straightening, cutting, testing to obtain qualified pipe products. It only takes about 10 minutes from forming to packaging for a titanium welded pipe, and the production and inspection process are all automated.
2. Uniform wall thickness and high dimensional accuracy, less surface defects, high reliability. The uniformity of the wall thickness of the finished pipe is very high, and more importantly, there is no microcrack formation on the inner surface.
3. The weld seam strength is higher than the matrix strength. The welding of titanium tube adopts the optimized tungsten electrode argon gas protection welding with matrix metal self-fusion welding process, which does not fill the external metal, so as to ensure the unity of weld and matrix composition.
4. Cost advantage of titanium welded pipe. Competition in China's titanium welded pipe market is particularly fierce, and the product price has long been hovering at a historical low, and far lower than the price of similar products seamless pipe.

Surface of Titanium Welding Pipes

Titanium and titanium alloy have the advantages of high strength and good corrosion resistance, and are suitable for making thin-wall heat transfer parts. When it is used as a heat transfer element, the surface is smooth and the adhesion force is small, which can effectively prevent scaling and ensure a stable thermal conductivity for a long time. Gr1, Gr2, and Gr12 Titanium have moderate strength, good plasticity and good cold processing performance, and have been processed into various kinds of heat exchange tubes, which are widely used in the condenser and heat exchanger of nuclear power, seawater desalination, petrochemical industry, refrigeration, environmental protection and other fields. Titanium welded pipe will be more and more demand, the application field will be more and more extensive.
