What is the cause of the corrosion of the ship plate?

Nowadays, many ship hulls are made of metal materials, but the metal materials in the sea water are affected by the sea water temperature, atmosphere and salt concentration, which often lead to hull corrosion, and the degree of hull corrosion is also very deep. After the corrosion of the hull, it often leads to the damage of the hull structure, and sometimes endangers the lives of the crew. Therefore, we need to understand the causes of corrosion of ship plate to facilitate maintenance.

1. Hull design factors
There are many factors causing hull corrosion, and the design of hull is one of the important aspects. In the design of hull cladding, the maintenance of hull cladding is not fully considered. The watertight device of the hull has no reliability, the hull has no corrosion resistance, and the watertight device related to the pipeline in the hull has no corrosion resistance. There is no corresponding preventive measures for the existing cracks of some hulls, resulting in serious corrosion.

2. Environmental factors
There are many reasons for hull corrosion, usually due to the degradation or damage of hull materials caused by various environmental factors. Therefore, the corrosion resistance of hull materials is related to environmental factors. The main material of hull is steel, which is divided into low alloy steel and carbon steel. Some of the most important environments outside the hull are seawater immersion.
