Abstract

PURPOSE:To prevent the generation of uneven distribution of temperature on metallic tubes due to cooling water penetrating into the tubes from both ends of the tubes nonuniformly hardened duct to uneven distribution of temperature in heating and hardening the metallic tubes by jointing the tubes so as to harden the tubes uniformly.
