Problems solved by technology

[0003] Due to the rapid development of material technology, the strength level is getting higher and higher, and the possibility of manufacturing large-scale spherical tanks is increasing. The existing large-scale spherical tanks (1000m 3 or 1000m 3 The above) generally adopt the pillar-supported orange segment or hybrid spherical shell plate, which still has certain limitations in saving materials and improving the stability of the spherical tank.

Abstract

The invention relates to an assembly method of a shirt support and a spherical shell plate of a 1000m<3> nitrogen spherical tank, which comprises the steps of: assembling bulk spherical tanks; setting up an inner scaffold and an outer scaffold; installing and welding a positioning block; manufacturing and installing a ladder and a platform; preheating before the welding; welding lifting points; assembling the spherical tanks; dismantling the scaffolds and the positioning block; and thermally treating the whole spherical tank. The invention increases the stress area of supporting the spherical tank, also reduces the stress concentration of fillet welds in contact with uprights, and has uniform stress, good stability and reliable connection. The quantity of the spherical shell plates is reduced to 18, which reduces the workload for the manufacture of the spherical tank. The invention increases the quality of the whole spherical tank, improves the safety factor of the operation of the spherical tank, greatly lowers the total installation cost, remarkably enhances the safety of the spherical tank, prolongs the service life of the spherical tank, and decreases the operation and maintenance cost of the spherical tank.

Description

technical field [0001] The invention belongs to the technical field of welding engineering, in particular to a 1000m 3 The invention relates to an assembly method of a spherical shell plate and a skirt of a nitrogen balloon tank. Background technique [0002] Spherical tanks are widely used in urban public and civil industries (city natural gas, liquefied petroleum gas), metallurgical industries (oxygen, nitrogen, argon), chemical industries (many Flammable, explosive, toxic chemical products) and other industries. [0003] Due to the rapid development of material technology, the strength level is getting higher and higher, and the possibility of manufacturing large-scale spherical tanks is increasing. The existing large-scale spherical tanks (1000m 3 or 1000m 3 The above) generally adopt pillar-supported orange segment or hybrid spherical shell plate, which still has certain limitations in saving materials and improving the stability of the spherical tank.
