Embodiment Construction
[0024] The present invention will be further described below in conjunction with drawings and embodiments.
[0025] Such as figure 1 As shown, the deck pass-through part of the present invention comprises a pass-through steel pipe 1, flanges 2 at both ends welded to the pass-through steel pipe 1, sleeve pipe 3, and web 4 respectively, and the sleeve pipe 3 is set on the pass-through steel pipe 1. Both ends are welded in the middle of the steel pipe 1 through the cabin, and the web 4 is loosely sleeved on the casing 3 . The overall galvanization of the deck tank in this embodiment can improve its ability to resist seawater corrosion. Since the diameter of the casing is 2-3 mm larger than the outer diameter of the steel pipe 1, a cylindrical air insulation layer 5 with a uniform thickness of 1-1.5 mm is left between the casing 3 and the steel pipe 1, which can reduce the number of casings 3. When welding with the web 4, the welding heat conducted from the casing 3 to the steel...
