ASTM A333 Gr.3 Seamless Carbon Steel Pipe

lntroduction

Seamless pipe is a long strip of steel with a hollow section and no seams around the perimeter. The thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing cost will increase significantly; The process of the product determines its limited performance, and the accuracy of the general seamless steel pipe is low: the wall thickness is uneven, the brightness of the inner and outer surfaces of the tube is low, the cost of sizing is high, and there are pockmarks and black spots on the inner and outer surfaces that are not easy to remove; Its inspection and shaping must be processed offline. Therefore, it reflects its superiority in high pressure, high strength and mechanical structure materials.
