Austenitic stainless steel spherical storage tank

Abstract

The invention discloses an austenitic stainless steel spherical storage tank. The austenitic stainless steel spherical storage tank comprises a spherical shell and a manhole, a plurality of equidistantly distributed upper-segment supporting columns are welded to the outer surface of the spherical shell, and lower-segment supporting columns are fixedly connected to the bottoms of the upper-segmentsupporting columns. Connecting pipes are arranged at the top and the bottom of the spherical shell, and safety accessories are arranged on the outer surfaces of the connecting pipes. Meanwhile, a plurality of base plates are welded to the front surface of the spherical shell, inclined ladders, transferring platforms, spiral ladders and top platforms are correspondingly welded to the outer surfacesof the multiple base plates, the spherical shell, the upper-segment supporting columns, the manhole, the connecting pipes and the base plates are made of austenitic stainless steel materials, and thelower-segment supporting columns, the top platforms, the spiral ladders, the transferring platforms and the inclined ladders are made of carbon steel materials. According to the austenitic stainlesssteel spherical storage tank, the spherical shell, the upper-segment supporting columns, the manhole, the connecting pipes and the base plates are made of the austenitic stainless steel materials, thebase plates are adopted to divide the inclined ladders, the transferring platforms, the spiral ladders, the top platforms and the spherical shell, the spherical shell can be effectively prevented from being polluted by iron ions, and thus the service life of the austenitic stainless steel spherical storage tank is ensured.

Description

technical field [0001] The invention relates to the technical field of storage devices, in particular to an austenitic stainless steel spherical storage tank. Background technique [0002] The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere.

[0002] The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, etc. Chemical products are needed to serve them. Some chemical products have played an epoch-making role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Human early life relied more on natural resources. The direct use of substances, gradually the inherent properties of these substances cannot meet the needs of human beings, so various processing technologies have been produced, which consciously and purposefully transform natural substances into new substances with various properties, and gradually develop them on the scale of industrial production Broadly speaking, anyone who uses chemical methods to change the composition or structure of substances or to synthesize new substances belongs to chemical production technology, that is, chemical technology. The products obtained are called chemicals or chemical products. With the development of society, the equipment is developing towards the direction of large-scale. Most of the storage pressure vessels use spherical storage tanks. Because the shell of the spherical storage tank is evenly stressed, under the same diameter and the same working conditions, the film stress of the spherical container is only the same thickness of the cylinder. Half of the hoop stress of the container, the corresponding pressure-bearing capacity is strong, and the surface area of ​​the spherical shell is the smallest, the weight is light, and the volume is the largest under the same volume. Therefore, large-scale storage pressure vessels use spherical storage tanks. Storage tanks have been widely used, but some media are stored in spherical tanks made of carbon steel and low alloy steel, which cannot meet the requirements of corrosion and prevention of iron ion contamination of the medium, thus reducing the service life of the storage tank. For this reason, we propose a Austenitic stainless steel spherical storage tank
