During the construction of hot-dip shipbuilding use GL-D hull structural steel galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the shipbuilding use GL-D hull structural steel construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, shipbuilding use GL-D hull structural steel welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
