What Are The Reasons That Affect The Widespread Application Of Titanium Fittings?

At present, the manufacturing process of titanium pipes on the market is basically mature, but the application of titanium pipes has always been constrained by costs, especially for specific requirements such as thin-walled pipes, high-strength pipes, and longer pipes. The production difficulty of titanium seamless pipes is high, the equipment is complex, the cycle is long, and the yield is low. So, titanium welded pipe fittings emerged.
Titanium pipes are not without corrosion in the environment. Titanium pipe manufacturers have found that pure titanium condenser tubes have severe corrosion perforation and edge rupture on both the inner and outer surfaces after 15 years. In addition, during the assembly and application process of titanium pipes, it is often necessary to bend, weld, and process the ends of the pipes. Due to the high yield to elasticity ratio of titanium pipe fittings, the rebound is obvious during bending, and excessive rebound makes it difficult to control the geometry and accuracy of the pipe.
During the process of pipe processing, the deformation of each pass significantly affects the performance of the pipe. A large amount of deformation can not only improve production efficiency but also better break down the coarse cast structure, making the grain size of the pipe fine and uniform. However, excessive deformation can increase the forming resistance of the pipe, resulting in local temperature rise and uneven deformation and abnormal grain growth. Reasonable deformation can form textures in the radial, axial, and circumferential directions of the pipe, thereby improving its performance.
