20000立方米内浮顶原油储罐设计毕业设计

Abstract

Based on the engineering design, work of 20，000 m3 large roof c0ne bottc,m avfiationkerosene tank，make the design analysis of over 32 m diameter roof with rib Comparison was made for inter floating roof tank with fixing roof tank , shell design technical requirements for shell of inter floating rooftank were described from aspects of lay2out of shell , function , fabrication and inspection etc. , the relevant matters and the reformation procedures werediscussed for reforming from fixing roof tank to inter floating roof tank.

Key words : inter floating roof tank ; fixing roof tank ; venting hole ; spreading tube ; hole for oil measure ; guide tube；large tank，roof design
