During the use of plastic storage tanks, situations such as tank bursting or bulging may occur. Due to the limited load-bearing capacity of the storage tank's connection surfaces, reinforcing ribs are added to the common vertical surface of the two bodies to increase the strength of the surface and ensure the strength and rigidity of the plastic components. Key design points for the reinforcing ribs of PE rotational molding storage tank containers:
(1) Replacing a single, taller reinforcing rib with a lower height, but slightly more numerous ones to prevent surface indentation during cooling and shrinkage of the thicker ribs at the bottom.
(2) The arrangement of the fibers is consistent with the filling direction of the molten material.
(3) The root of the tendon is transitioned with a circular arc to prevent stress concentration and subsequent damage when subjected to external forces. However, an excessively large radius of the rounded corner at the root can lead to indentation.
(4) No parts are generally mounted on the shaft.
(5) Avoid placing the bosses too close to the inner wall of the product to prevent insufficient filling of the localized melt.
