Abstract
The invention discloses a method for manufacturing a spherical tank. The method includes the steps of 1, material preparing; 2, blank discharging; 3, cold press molding; 5, bevel cutting; 6, shell plate shaping; 7, ledge, connecting pipe and flange assembling and welding; 8, grinding and welding repairing; 9, rust removing, coating, packing and transporting. An operator conducts operation according to the step 1 to the step 9 in the method for manufacturing the spherical tank, all the operating steps for manufacturing the spherical tank have corresponding reference standards and corresponding implementation processes accordingly, and therefore the operator can conduct operation according to the processes; in this way, the working loads and the strength of the operator are greatly reduced, and labor and labor hours are saved; meanwhile, the manufacturing efficiency of the spherical tank is efficiently improved to a certain degree.
Description
technical field [0001] The invention relates to the technical field of spherical tank manufacturing, in particular to a spherical tank manufacturing method. Background technique [0002] With the development of industry, the application of large-scale spherical tanks is urgently needed by people. The shapes of spherical tanks are spherical and ellipsoidal. Most of them are single-layer spherical shells. When storing liquefied gas at low temperature and low pressure, double spherical The shell is filled with heat insulating material between the two layers of spherical shells. The most widely used is a single-layer spherical tank. The spherical tank is welded with multiple spherical shell plates, and the multiple spherical shell plates are pressed into a spherical surface by multiple pieces. Ball petals are assembled and welded by orange split method, football split method or mixed football split method. [0003] However, the existing spherical tank manufacturing methods ar...
