Vessel is an effective and efficient medium of sea transportation
because it can transport goods in a large number. In planing and
constructing the vessel, therefore, it is not only striven to be
economical without decreasing its function, instruction of
classification, and contruction power, but also simple to get the
treatment. It will make the vessel more durable and the condition of
equipment structure more stable to support the operation. One the
important project and construction is to determine materials that will
be used on the vessel. Pipe is a dominant component in operational
system of each activator engine. Besides, it is as medium to transfer
bold fluid and gas from a space to another space. Hence, it is important
to protect the pipe from decreasing function which is caused by
corrosion, so that damages the pipe. Considering the high vessel
reparation fee, it is better to shade the pipe from the damages. The
most efficient and the easiest protection and treatment to reduce
corrosion in a pipe system is by using Galvanized method
