The bending strength of the steel pipe and steel pipe wall thickness has little

 

Steel pipe should be the deflection limiting their strength requirements as flexural capacity before the probe beam is used on both sides, both of which are closely related with the inside and outside diameter of the steel pipe, such as pure mechanical analysis, the moment of inertia and the cross-section of the steel pipe the coefficient of correlation, while the moment of inertia of the section modulus of the steel pipe (tube) are respectively equal to the 4 th power of the outer diameter of the steel pipe with inner diameter of the fourth power of the difference multiplied by π except 64 and equal to the 4 th power of the outer diameter of the steel pipe with an inner diameter 4 th power of the difference multiplied by 0.0892 In addition the outer diameter of the steel pipe. When the determining factors of the inner and outer diameter of the steel pipe, the steel pipe wall thickness will naturally be included, of course, can also be seen that the role of the diameter of the steel pipe wall thickness to be significantly.
