The thicker the wall thickness is, the more economical and practical it is. The thinner the wall thickness is, the higher its processing cost will be 2. The process of titanium seamless pipe determines its limited performance. Generally, the precision of seamless steel pipe is low, the wall thickness is uneven, the brightness of the inner and outer surface of the pipe is low, the sizing cost is high, and there are pockmarks and black spots on the inner and outer surface, which are not easy to remove 3. Its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure, high strength and mechanical structure materials.
