CARBON STEEL PIPE
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading carbon steel pipe manufacturer and supplier
Carbon steel pipes are primarily categorized into seamless steel pipes and welded steel pipes based on their manufacturing processes. Their main composition consists of iron-carbon alloys without other alloying elements. They can be classified into low-carbon steel, medium-carbon steel, and high-carbon steel according to carbon content. As carbon content increases, strength and hardness improve, but ductility and weldability decrease.Carbon steel pipes exhibit excellent strength and toughness, capable of withstanding high-pressure loads. Additionally, carbon steel pipes possess good machinability and weldability, enabling their extensive application across various scenarios. A drawback of carbon steel is its relatively poor corrosion resistance, making it susceptible to oxidation and corrosion in humid or extreme environments. Consequently, secondary treatments like epoxy coating or hot-dip galvanizing are often applied under harsh operating conditions to enhance durability. Due to their relatively low cost and reliable performance, carbon steel pipes are extensively used in construction, machinery manufacturing, energy transmission, and other industries.
As a leading manufacturer and supplier of carbon steel pipe products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
