The characteristics of structural design in the manufacture of titanium equipment 

The corrosion resistance of titanium equipment is also related to the size of the room. The possibility of corrosion in the narrow return line is greater than that of Jarisui. When titanium is connected to non-metallic materials, the corrosion tendency of seam corrosion is much greater than that in the titanium-titanium barrier. In fact, Common barrier corrosion in equipment also mostly occurs on the flange sealing surface connected to the non-metallic hot plate. Titanium pipes will also undergo barrier repair and corrosion in hydrochloric acid, ketone, oxalic acid and formic acid solution. This kind of titanium tube and Dahequan have unique characteristics in physics, chemistry, mechanics, corrosion resistance and process performance. Therefore, the structure design cannot directly apply the commonly used ferrous metals and other non-ferrous gold exhibition equipment structures. According to the performance characteristics of titanium materials, this regulation proposes a general rule for the structural design of titanium equipment, and titanium equipment manufacturers should also pay attention to it. 

1. Because the mechanical solutions of titanium and titanium alloys are different from steel, the pressure ratio of titanium is high, the plastic deformation range is contained, and the springback during cold stamping and cold inspection is large. Therefore, the structure of titanium equipment is required to be simple and good at the same time. The structure is also stupid than the cleaning of the table 5 near the green connector, which is convenient to use gas to protect the slow, protect the front, measured by the Tan Pei connector on the back 

2. Titanium can be welded with steel, niobium, tantalum, and lead metals, and there will be no brittleness after welding. This is because these metals are highly soluble in titanium, but titanium has poor mutual melting characteristics with steel and other metals, so titanium It cannot be directly welded with other metals, and can only be connected by bonding, brazing coal, explosive media and bolts.

3. Titanium has poor impact and initial fracture properties, so the continuity of the structure and the smoothness of the weld should be maintained during the design, and stress should be avoided as much as possible.

4. Purely in the oxide solution, it is easy to produce high corrosion in the sister courtyard, but the crevice corrosion of titanium is closely related to the temperature, oxide concentration, pH value and the size of the training barrier. 

5. The plastic deformation range of titanium is fast and small, and there is obvious work hardening. Therefore, the bending and hiding edges of titanium parts usually adopt a larger bending radius, and a smaller expansion rate is used when the tube is stretched. 

In seawater and clad sodium salt water, when the temperature is below 149℃, the titanium will not corrode. When the temperature exceeds 12.1℃, the titanium will be in the barrier of the polar capacity, especially in the non-full thermal film. Corrosion occurs in the place, but when Tan Yi exceeds 149C
