  The fabricability, good corrosion resistance and high thermal conductivity of aluminum brass (Al-brass) material has made it widely used in heating coil units of crude oil carrier vessels. But because of bad brazing technique, unexpected leakage some times occurred. To know the exact bonding state, the ultrasonic and X-ray test of tube which was brazed were done. The ultrasonic test is not a good method to know brazing state of tube. By the X-ray test, it is recognized that to know the exact brazing state of Al-brass tube is possible. And a new heating method of brazing should be developed to get a good bonding state.
