At the beginning,
Considering the tube material is Q235 and the length of 20GP container is 5.89m, 6m tube is too long to put in. So

Introduction
Q235 is also called A3 plate.
Common carbon structural steel-plain plate is a kind of steel material.
Q represents the yield limit of this kind of material, and 235 in the back refers to the yield value of this kind of material, which is about 235MPa.
It is widely used because of the low carbon content, better comprehensive performance in strength, plasticity and welding properties.
