摘要
The present invention relates to a baffle in an LNG ISO tank, and more particularly, to a baffle for preventing cracks in end welds by alleviating the water hammer phenomenon that occurs when transporting LNG. The water hammer prevention baffle in the LNG ISO tank according to the present invention includes a plurality of baffles, a tank frame, and a weld end. The plurality of baffles includes an upper hole, a lower hole, and a manhole. In addition, it is preferable that the plurality of baffles do not directly hit the welding end of the liquefied gas when the inner liquefied gas reciprocates in the axial direction by crossing the bottom hole and the manhole. In addition, it is preferable that the welding portion is located at the end and not directly abutted on the bottom hole of the baffle in the axial direction. According to the present invention, there is an effect of buffering the axial impact of the internal liquefied gas since a plurality of baffles have a bottom hole and a manhole alternately drilled with each other. In addition, according to the present invention, the internal liquefied gas cannot directly impact when the water hammer occurs because the welding part and the lower hole of the baffle intersect with the axial direction of the tank.
