1500M3球型储罐设计 摘要 球罐大容量、承压的球形储存容器，广泛应用于石油、化工、冶金等部门，它可以用来作为液化石油气、液化天然气、液氧、液氨、液氮及其他介质的储存容器。也可作为压缩气体（空气、氧气、氮气、城市煤气）的储罐。 设计主要按照GB12337—1998《钢制球形储罐设计》进行设计本设计共分两部分，第一部分包括球罐的设计；第二部分为外文资料及其对应的中文翻译。其中第一部分介绍了球罐的发展状况和应用场合、材料选择、球罐设计、结构确定、强度计算、绘图等内容。以结构强度的设计计算为主，从基础理论、设计方法、结构分析、标准规定等方面进行了系统的阐述。 本球罐在MPa的设计压力、常温的设计温度下设计，设计厚度为mm，焊接接头系数采用100%无损检测选用1.00，压力试验采用水压试验，水压试验压力为MPa，球壳材料选Q345R,支柱采用赤道正切式支柱式支承，为了承受风载荷和地震载荷，保证球罐的稳定性，在支柱之间设置拉杆相连，球壳采用的是三带混合式，球壳分块少，板材利用率高，制造工作量小，焊缝短，焊缝个数少，检验量小，施工速度快，使球罐的施工质量易于保证，拉杆结构采用可调节式拉杆，使球罐平衡易于调节。 但在本次设计中由于设计者水平有限，所以难免会出现漏洞和不足，望指正。 关键词：球形储罐、压力容器 Abstract As a large-capacity tank, pressure the ball storage container, widely used in petroleum, chemical, metallurgical and other departments, it can be used as a liquefied petroleum gas, liquefied natural gas, liquid oxygen, liquid ammonia, liquid nitrogen, and other media storage container . Also available as compressed gas (air, oxygen, nitrogen, city gas) storage tank??? Designed in accordance with the GB12337-1998 “Design of steel spherical tank”， this design is divided into two parts, the first part includes an overview and design of spherical tank including the calculation of spherical tank; the second part includes an English paper with 20,000 characters and its corresponding Chinese translation. The first section describes the development of the sphere and applications, material selection, spherical design, structure identification, strength calculation and so on.The most important is the calculation,and I also introduce the structural design ,the basic theory, design methods, structural analysis, standards. The spherical design at 1.77MPa pressure and Room temperature and the design thickness is 46mm. The use of welded joints coefficient selection of 100% non-destructive testing 1.00, and use the hydraulic pressure test with 2.22MPa, ball shell material selection,.I use the equator tangent pillar strut-type support.In order to bear wind and seismic loads and ensure the stability of spherical,I set
