The comparison of bearing strength between carbon fiber pipes and steel pipes requires consideration of various factors, such as pipeline size, material strength, and pipeline manufacturing process.

In general, carbon fiber pipes have higher specific strength and stiffness than steel pipes of the same size, as carbon fiber is a high-strength and low-density material. Moreover, carbon fiber pipes are not easily corroded, and their surface is smooth and not prone to rusting.

In some cases, steel pipes are more suitable for heavy-duty applications than carbon fiber pipes because they have higher toughness and plasticity, allowing for plastic deformation when subjected to large external forces, thereby maintaining structural integrity. Carbon fiber pipes may break when subjected to excessive external forces.

Therefore, in specific application scenarios, multiple factors need to be considered to select suitable pipeline materials, including factors such as bearing capacity, weight, durability, cost, etc.
