1. Seamless steel pipe technology determines its performance limitations, the general low precision seamless steel pipe, wall thickness unevenness, low brightness inside and outside the tube, the length of the high cost and there are pockmarks inside and outside, black spots are not easy to remove.

2. Its detection and shaping must be processed offline. Therefore, it shows its superiority in high pressure, high strength and mechanical structure materials.

3. The thicker the thickness of seamless steel pipe it has greater practicality, if the thinner the thickness of its processing costs will increase.
