| Abstract: | Based on the Spangler's formulas that are widely used for calculating the intrnal force and deflection of pipe wall in design of flexible pipes,this paper inquires the minimum of pipe stiffness,the. minimum of the ratio of wall thickness to diameter(i. e. t/d) the critical internal pressure,the,scope of t/d that is satisfied with strength condition and the principle of determining t/ d. A simple method for design of flexible pipes is provided. |
