Features of Seamless Product
1. The product shows more excellent economical efficiency and practicability with the increase of the wall thickness. The production cost would increase substantially when the wall thickness is very small.

2. The seamless stainless steel pipe is bound to have limitations by the production process. It often has low accuracy, uneven wall thickness, low brightness of inside and outside surface, high sizing cost, as well as pit and black spot on interior and exterior surface which are not easy to remove.

3. The detection and shaping must be processed off-line. So, the product presents the superiority in high pressure, high strength and mechanical structure.
