Discussion on Manufacturing Technology of Ultra-Long, Ultra-Thin, Large-Diameter Seamless Steel Pipes
An ultra-long, ultra-thin seamless steel pipe forging has the following specifications: length ≥11000mm, raw pipe wall thickness ≤25mm, finished wall thickness: 15+0.50mm, outer diameter: 800+10mm. This product is widely used in the preparation of blanks for spin forming processes in certain aerospace products. The manufacturing of such ultra-long, ultra-thin, large-diameter seamless steel pipes, especially the control [...]
