Wall thickness of the inner steel tube is less than a wall thickness of the outer steel tube, and maximum carbon content of the outer steel tube alloy is greater than a maximum carbon content of the corrosion resistant steel. Thickness of the fuel line is ranged between 5 wt.% to 60wt. % of inner diameter of the fuel line.",
