Abstract
In recent, the price of vessel have got higher and higher due to construct a large size, specific purpose and enforce the international rules of stability. So the vessels must be considered from the designing and building the vessel in the shipyard what is the best way to operate maximum ratio without trouble and repair.

The basic formation of this study is composed at first each characteristics of a natural basalt and fused cast basalt, re-crystallization of cast basalt and its properties, secondary the test way of fused cast basalt regarding compressive strength, bending strength, hardness, absorbtion and neutral salt spray test, thirdly the manufacturing process of fused cast basalt tube and bend, fourthly the way of inserting the liner in the steel tube and mortaring between steel casing and basalt liner, fifthly the characteristics of steel-fused cast basalt lined pipe regarding the safety standard of mechanics, thermal strength, temperature distribution of each cylinder wall, insulation test and bending strength.

Steel-fused cast basalt lined complex pipe is developed by inserting the basalt tube inside of steel pipe to protect the corrosion and abrasion of steel pipe to transport seawater of vessel by protecting of direct touch seawater to steel. Also fused cast basalt tube have a high chemical resistance and anti-abrasion characteristics, so this pipe will be used without repair till to her whole life.

Mortar for sticking of tube and steel pipe is also important to decide the quality of complex pipe. Because steel pipe has a high toughness and strength also fused cast basalt has a very high corrosion and abrasion resistance, by complex together them.

This thesis have been studied to use seawater pipe line for the permanent material with economic point and environment.

To apply this composite pipe in the vessel, during the design and construction of vessel in shipyard it need a review the safety guard of moment and radius, temperature distribution factors of each materials which are steel, mortar and basalt liner, the heat stress due to it has a different heat expansion coefficient steel and basalt liner, insulation resistance to check the sea water flow out from the basalt liner and touch with the steel pipe, bending moment due to it has a heavy weight and need the support bar at the middle portion between distance line, and the test of impact on the basalt liner due to it has a brittle.

From the experiment and study, the application of steel-fused cast basalt tube at the sea water line will be expected to increase effective profit balance of vessel due to without charge of management and maintenance until her whole life.
