1. Carry out anti-rust treatment for Q345B seamless square tube, Q345B cold-drawn square tube maintenance and stacking knowledge, the key to use steel brush to polish its surface when Q345B seamless square tube anti-rust treatment, Q345B cold-drawn square tube This kind of method can reasonably remove the rust stains on the surface of the Q345B seamless square tube that is loose or warped.
2. Clean up the surface of Q345B seamless square tube, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co., Ltd. is cleaning up Q345B seamless square tube , Use organic solvents or solvents to clean up the surface. The maintenance and stacking knowledge of Q345B cold drawn square tubes is used to remove oil and dust. Q345B cold drawn square tubes use organic chemistry and electrolysis. Method, Q345B cold drawn square tube is only suitable for removing vegetable grease on the surface of Q345B seamless square tube, and dust cannot remove rust and oxide scale. Therefore, this type of method can only be used as an auxiliary in anti-corrosion production and manufacturing. Way.
3. Carry out pickling passivation for Q345B seamless square tubes. When pickling passivation for Q345B seamless square tubes, one will use organic chemistry and electrolysis. The Q345B seamless square tube pipeline removes the oxide scale. It is often divided into two methods. The reason for the development is that chemical water treatment can only clean the surface completely. For some crevices, it is difficult to achieve the results that everyone feels.
