MEMBRANE PANEL FOR A LIQUID STORAGE TANK

摘要

PURPOSE: A metal membrane panel for a fluid storage tank is provided to reduce manufacturing costs and to simplify manufacturing procedures because an additional mold for manufacturing a membrane panel is not necessary. CONSTITUTION: A metal membrane panel for a fluid storage tank comprises first direction corrugations(20), second directional corrugations(30), and rectangular bottom parts(40). The first directional corrugations are arranged in a parallel each other to form a primary barrier wall of a low temperature fluid storage tank. The second directional corrugations are crossed with the first directional corrugations and are arranged in a parallel. The rectangular bottom parts comprise intersection parts(100) and are formed by the first directional corrugations and the second directional corrugations. The first directional corrugations comprise first grooves formed in a direction vertical to the first direction at the intersection parts. The second direction corrugations comprise second several pairs of second grooves which are formed in both sides of the first grooves facing each other.
