T12 alloy steel pipe because the material is so called T12 T12 alloy tube. T12 alloy tube is a product of a seamless steel pipe. The solid tube after inspection and removal of surface defects and cut into desired length end to end in the tube perforation surface centering, and then sent to the furnace heating, puncher perforation. In perforation while constantly rotating and forward roll and the role of the head tube gradually formed within the cavity, said capillary. Automatic pipe rolling mill and then sent on to continue rolling. Finally, are machine are whole wall thickness sizing, sizing machine within specification. The use of continuous pipe mill production of hot-rolled T11 alloy tube is a state-of-the-art methods. If the caliber of the production is relatively small, relatively high accuracy and surface appearance quality requirements of steel pipe on the process for the production of cold drawn. T12 alloy tube in the high-pressure pipeline, container, heat exchangers, boiler tubes, power plants and other applications is very wide. http://tjdsgg.cn
