Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.Product News about Seamless Steel Pipe and Welded Steel PipeSeamless black steel pipe; 2019 08 13 Material classification of pipe fittings; 2019 08 09 Small diameter seamless steel pipe; 2019 08 05 Seamless elbow forming; 2019 06 27 Seamless steel pipe wt class; 2019 06 26 G3452 Steel Pipe; 2019 06 25 Short joint welding of oil casing; 2019 06 20 Steel pipe News Tianjin Wanlei Steel Pipe Co.A333 Gr.6 Seamless Steel Pipe Was Delivered To The Client [Apr 30, 2020] Third Party Inspection For Seamless Steel Pipes [Apr 24, 2020] 20 inch And 24 inch Seamless Steel Pipes
