A New type of Online Accelerated Cooling Equipment for Seamless Steel Pipe and Its Application Experiments

A new type of online accelerated cooling equipment for seamless steel pipe and its application experiments were introduced in the present work. The equipment can simultaneously cool the inner and outer surface of seamless steel pipes. By using online accelerated cooling process, the mechanical properties of the test steel pipe made of Q345B composition meet the requirements of Q460E steel grade index, with the yield strength of 460~475MPa, the tensile strength of 601~603MPa, the elongation of 21.5~26.5%, and the -40°Cimpact energy of 136J.
