The wall thickness calculation result is more reasonable and the circumferential stress distribution is more homogeneous when the safety factor of tensile strength is taken to be 2.4. Taking the 20×10 4 m 3 oil storage tank and selecting a proper welded joint efficiency, the wall thickness is calculated by the presented optimization method. In order to make up the deficiency, an optimization method based on API 650 is presented, which considers the effects of yield strength, tensile strength and yield ratio on the determination of allowable stress. Heading 8.1 Plain members and mechanically fastened joints 8.2 Welded built-up sections 8.3 Transverse butt welds 8. Details are tabulated in BS EN (hereinafter denoted EC3-1-9) and are separated into the following headings. 14,015/year is in the bottom 10 of workers in the United States. that can be used for fatigue damage calculations. While for the tanks made of high strength steel, like 12MnNiVR (GB 50341), the yield ratio of the steel has reached 0.803, which is larger than the upper limit value of API 650. Use this easy calculator to convert an annual salary to its equivalent as an hourly wage. The wall thickness calculation result applying the method of API 650 is more reasonable than other standards. Like API 650, EN 14015 computes the shell course required thickness via a fairly straightforward equation as shown here: Where: c is the corrosion allowance in. In section 10.5.

Both EN 14015 and API 650 give guidelines for fuel storage tank design for small internal pressure.

Results show that as the volume of oil storage tank increases, some wall thickness calculation results of the standards have been larger than the allowable value, leading to the unreasonable distribution of the wall circumferential stress. This document was uploaded by user and they confirmed that they have the permission to share it. TANK design software performs calculations in accordance with the latest API. Storage tank shell thickness calculation tool based on the API 650 and EN 14015 standards allows you to estimate material consumption for the cylindrical shell of a tank and to compare how steel grade affects material consumption. Taking three oil storage tanks with different volumes of 10×10 4 m 3, 15×10 4 m 3 and 20×10 4 m 3 for examples, the wall thickness calculation methods of API 650, GB 50341, JIS B 8501 and BS EN 14015 have been analyzed and compared. Optimization calculation method determining wall thickness for large oil storage tank made of high strength steel is investigated in this paper.
