How do titanium tubes take shape?

Titanium is formed at room temperature, a process similar to one in steel.
Titanium is less malleable at room temperature than one of the other structural metals. This automatically results in reduced stretch forming and a large bending radius. Due to this characteristic, thermoforming is sometimes used, especially if more intense bending is required (or in the case of stretch molding).
Titanium's elastic modulus is half that of steel, which means that the molding process can cause significant rebounds (which the manufacturer will compensate for).
Similarly, lubrication is an important part of the tube molding process, given the wear trend of titanium (greater than the wear trend of steel).
Preparation for molding
In most cases, titanium does not require additional action prior to molding operation. They can be used after receiving ingots, but this may not always be effective.
When any traces on its surface (e.g. chisels) are noticed, they are removed by different treatments (sandblasting, pickling, etc.). In addition, if there are any sharp edges, smooth them before the actual pipe molding process. Otherwise, there is a risk of cracking edges, which can affect the quality of the final product.
The molding type
Titanium tubes can be formed by two methods: cold and hot molding.
Cold molding
Titanium tubes are formed at low speeds and at room temperature, taking into account the elongation of metals. Therefore, the stretch test will be performed. The manufacturer will eliminate the rebound by using thermal training on the molded titanium tube.
It is well known that the malleability of titanium, including bending and stretch forming, increases with temperature. As a result, titanium tubes are usually made at high temperatures. As the temperature increases, it becomes easier to form titanium tubes.
Using this method, the rebound is virtually eliminated when grade 5 titanium (Gr5 TC4) is formed.
The titanium tube is bent
Titanium tubes are bent using conventional equipment. The spindle elbow machine is the first choice for small radius bending. In order to minimize the sagging trend of titanium, proper lubrication must be made of elbow equipment and wiper molds. For best results, the bending process should be carried out at low speeds.
How are titanium seamless tubes manufactured?
The seamless tube can be made of commercially pure titanium or one of the existing titanium alloys.
Initially, titanium ingots were processed at temperatures ranging from 850oC to 1250oC and eventually reduced to 600oC to 1100oC.
As a result of the treatment, solid blanks are given. It is then turned into hollow blocks through the perforation process at temperatures ranging from -100oC to 1250oC.

Dimension by elongation, and then take the reduction step. This occurs at temperatures between 600oC and 1100oC, resulting in a decrease in the outer diameter. Finally, the pulping step will be performed at a varying temperature between 550oC and 1150oC, which will further reduce the outer diameter.
