Oil tank design
Thread Content
The graduation project topic assigned to me by my teacher was: to design a lubricant storage tank with a capacity of 500 M³. To train us, the teacher said not to ask him any questions and to solve things on our own. I don’t really know how to design this in the first place, and the company I signed with requires the work to be done there; I have to travel back and forth every week, which leaves me with little time, so progress is very slow. I got a harsh critique from my teacher~~~ If anyone who has done similar designs can help, please share it. If you’re worried, you can delete the data and any information you don’t want to expose; I just need a design reference to see how it’s done, so as to avoid making mistakes and save some time. Any design for a lubricant storage tank of any capacity will do, whether it’s a diesel storage tank or a storage tank for some other type of oil; it would be useful to have references for such designs. I can’t find a single relevant design paper online; it’s frustrating~ I hope everyone can help by posting it on forums or sending it to my email address: 170125687@qq.com or brant888888@163.com. Thank you! ! ! This post was last edited by brant888888 on 2009-4-5 22:04.]
You can learn a lot by doing things hands-on. There are many experts on our forum, so if you have any questions, almost everyone will be quick to reply. Try to finish it by yourself:lol
I have the technical requirements for a 2,000 cubic meter tank for heavy crude oil; I assume their standards for implementation should be the same. Take a look for yourself to see if it can be helpful to you. The equipment is manufactured, inspected, tested, and accepted in accordance with GB50128-2005 \"Code for Construction and Acceptance of Vertical Cylindrical Welded Steel Storage Tanks.\" Both the longitudinal and circumferential weld joints of the tank wall are of the full-penetration butt type; the basic shape and dimensions of the weld grooves shall comply with the provisions of GB985-88, and E4315 electrode is used. The weld joint at the bottom of the tank shall be subjected to a tightness test using the vacuum chamber method; the negative pressure value during the test must be no less than 53 KPa, and it is considered qualified if there is no leakage. The fillet weld joints between the tank wall plates and the edge plates are subject to penetrant testing in accordance with JB/T4730.5-2005 \"Non-destructive testing of pressure equipment\", with grade I considered acceptable. Unless otherwise specified, the extension length of the take over is 200 mm (the distance from the flange sealing surface to the outer wall of the tank). The root thickness of all fillet welds and lap welds is equal to the thickness of the thinner of the two welded components, and the welding is continuous. Human body static electricity discharge devices in the form of stainless steel touch balls should be installed at the entrance railing of the spiral staircase and beside the sampling ports; the diameter of these balls should be between φ40 and φ50 mm, and they should be welded to the handrails in those locations. The spiral stairs and platforms shall be constructed and inspected in accordance with GB50205-2001 \"Code for Acceptance of Construction Quality of Steel Structure Engineering\". After all the oil tanks have been installed, a water filling test must be carried out. During this test, it is necessary to check whether there are any abnormal changes in the tank walls and whether there are any leaks in the welds throughout the tank. If any faults or defects are found, repairs must be made, after which another water filling test should be conducted. All anti-corrosion and insulation work related to the equipment are not included in this scope.
It is recommended to refer to the book \"Comprehensive Book on Chemical Equipment Design: Spherical Vessels and Large Storage Tanks\", which is available on the forum.
It is recommended to consult GB50341-2003 \"Code for Design of Vertical Cylindrical Welded Steel Oil Tanks\" or SH3046 \"Code for Design of Vertical Cylindrical Welded Steel Storage Tanks in Petrochemical Industries\"; these codes provide detailed specifications, requirements, and design calculations related to this topic； Carrying out a graduation project in accordance with the guidelines is like engaging in real practice, which will be very helpful in the future! For reference!
