For high value-added special ship type, due to different hull structure, special purpose and other reasons, GL DH32 steel plate is also put forward higher requirements.
In particular, the special hull structure of this type of ship leads to a significant reduction in the proportion of displacement to the total weight of the ship, resulting in a high center of gravity and poor stability. In order to ensure the stability of the ship, the thickness tolerance of GL DH32 steel plate must be controlled in a small range to prevent the excessive proportion of overweight steel plate, which will affect the operational stability of the ship.
The new classification society code requires that the average thickness tolerance of GL DH32 steel plate must be positive tolerance, which also increases the difficulty of controlling the thickness tolerance of GL DH32 steel plate to some extent.
The key point for the production of high value-added GL DH32 steel plate is to accurately control the thickness tolerance of GL DH32 steel plates while meeting the average positive tolerance of THE thickness of GL DH32 steel plate.
