<p>The present invention relates to a lattice pressure tank having an inner hollow portion. More specifically, the lattice pressure tank having a through-hole in the center is composed of a plurality of lattice plates arranged and spaced at a predetermined distance in the lengthwise direction, the width direction, and the height direction to form a hollow portion composed of a hollow space inside the lattice pressure tank by the through-hole. The lattice pressure tank is capable of increasing the strength of the pressure tank by the lattice plates, reducing omnidirectional stress, and having an inner work space even if the tank is formed in a small size.</p> |
