Conclusions of Investigation

1. Cr-containing oil coat may give Mariloy good corrosion

resistance to cargo oil environment.

　Inspection after 15-years service showed that Mariloy

pipe could be used without painting over 30 years in cargo

oil pipe environment.

2. There is no pit in the inside of water ballast pipe, though

all surfaces rusted. That means that general corrosion

occurred. As the maximum loss in wall thickness is 3.2mm

maximum after 15 years, Mariloy can be used without

painting over 30 years also in water ballast pipe

environment.

Conclusions

1. Good Corrosion Resistance

　Inspection after 15-years service showed that Mariloy

S-400 pipe could be used without painting over 30 years in

cargo oil pipe and in water ballast pipe environments.

2. Merit of Using Mariloy S- - 400 Pipe

　Using Mariloy S-400 gives you an economical and ecological solution;

vs. carbon steel pipe with painting: reduction in the fabrication and maintenance cost and time,

and solution to regulation of harmful paints.
