A single-shell multi-layer hybrid spherical storage tank and its manufacturing process

Abstract

A single-shell multi-layer hybrid spherical storage tank and its manufacturing process, including a hybrid shell with reserved manholes and inlets and outlets. The hybrid shell includes an equatorial zone, a temperate zone and a polar plate, wherein the equatorial zone and the temperate zone It adopts orange-flap type and the pole plate adopts football-flap type; the inner wall of the hybrid housing is provided with a lining layer, and the outer wall of the hybrid housing is provided with a compression layer, a tensile layer, an anti-rust layer and a wear-resistant layer in sequence from the inside to the outside. The structure of the storage tank is also more stable, effectively increasing the service life of the spherical storage tank. The invention has a simple processing process and is easy to implement, effectively improves the material utilization rate when manufacturing storage tanks, and reduces the waste of manpower and material resources caused by complicated processes. At the same time, it enhances the stability of the tank and ensures the sealing of the tank, making it difficult for gas or liquid to leak. It extends the service life of the spherical storage tank to a certain extent and reduces explosions and fires caused by leakage. and the possibility of an accident.

Description

technical field [0001] The invention relates to the technical process route field of spherical storage tanks, in particular to a single-shell multi-layer hybrid spherical storage tank and its manufacturing process. Background technique [0002] A spherical storage tank is a pressure vessel used to store liquid, gas or liquefied gas. Because of its advantages of thin wall thickness, light weight, less materials, low cost, and small footprint, it is widely used in petroleum, petrochemical, chemical, metallurgical and other industrial fields and some other industries. According to the form of the spherical shell, it can be divided into football petal type, orange petal type and the combination of the two, while the football petal type has complicated weld seam layout, difficult construction and assembly, and orange petal type has complicated blanking and molding, and the utilization rate of the plate is low, so generally Use a hybrid of the two. The hybrid type combines the t...

AI Technical Summary

Problems solved by technology

However, the structure of the single-layer spherical tank is relatively simple, and the wall thickness is thin.

Most of the spherical tanks store flammable, explosive or toxic media. Once an accident occurs, it will not only cause the leakage and release of the media, but also cause a series of serious accidents such as poisoning, pollution, etc.
