Re: [MW:12853] Calculation of Shell thikness according to API 650

 

Hi,

Please refer Section 5.6 (SHELL DESIGN) of API650.

5.6.3 Calculation of Thickness by the 1-Foot Method

5.6.4 Calculation of Thickness by the Variable-Design-Point Method

5.6.5 Calculation of Thickness by Elastic Analysis

 

Also please find below the minimum thickness requirement as per API650

 

5.6.1 General

5.6.1.1 The required shell thickness shall be the greater of the design shell thickness, including any corrosion allowance, or the

hydrostatic test shell thickness, but the shell thickness shall not be less than the following:

Nominal Tank Diameter                     Nominal Plate Thickness

    (m)             (ft)                                 (mm)             (in.)

< 15             < 50                                     5             3/16

15 to < 36     50 to < 120                         6              1/4

36 to 60         120 to 200                          8               5/16

> 60             > 200                                  10               3/8

Dear experts;
      I hope to inform me how i should calculate shell thikness
according to API 650 when i had only the hieght and diameter.
Please with advace
