The anti-corrosion and rust prevention of marine steel plates is of crucial importance. Here are some more detailed information:

Regular maintenance and inspection

Formulation of maintenance plans

According to the ship's usage and anti-corrosion and rust prevention requirements, formulate detailed maintenance plans. The maintenance plan should include inspection frequency, content, methods, and responsible persons.

The maintenance plan should be regularly evaluated and adjusted, and revised in time according to the actual situation to ensure the effectiveness and timeliness of maintenance work.

 

 

 

Inspection content and methods

Appearance inspection: Check whether the coating on the steel plate surface is complete, whether there are phenomena such as damage, blistering, and peeling. Appearance inspection can be carried out by visual inspection or with the help of tools such as magnifying glasses and endoscopes.

Thickness measurement: Use a coating thickness gauge or ultrasonic thickness gauge to measure the coating thickness and the remaining thickness of the steel plate. Thickness measurement should be carried out at representative locations to ensure the accuracy of the measurement results.

Potential detection: Use a reference electrode and potentiometer to detect the potential of the steel plate and judge the working state of the cathodic protection system. Potential detection should be carried out regularly to ensure that the steel plate is always in a protected state.

Water quality analysis: Analyze the seawater around the ship to detect parameters such as salt content, dissolved oxygen, and pH value to understand the corrosiveness of seawater. Water quality analysis should be carried out regularly, and corresponding anti-corrosion measures should be taken according to the analysis results.
