How to store carbon steel pipes?
Carbon steel pipes are manufactured from steel ingots or solid round steel by perforating them into rough pipes, followed by hot rolling, cold rolling, or cold drawing. With good strength, toughness, and relatively low cost, carbon steel pipes find widespread use in industries such as construction, machinery manufacturing, chemicals, and petroleum. Applications include structural support for buildings, machinery components, and fluid transport pipelines. Common materials for carbon steel pipes include Q235B and Q345B. Q235B offers decent elongation, strength, good toughness, castability, and ease of stamping and welding. Q345B, a low-alloy steel, provides excellent overall mechanical properties, good low-temperature performance, plasticity, and weldability.
