The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost. Secondly, the technology of the product determines its limited performance. Generally, seamless steel pipes Low precision: uneven wall thickness, low brightness inside and outside the tube, high cost of sizing, and there are pits and black spots on the inside and outside that are not easy to remove; thirdly, its detection and shaping must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.
