About iron or steel (excluding cast iron); line pipe of a kind used for oil or gas pipelines (not seamless), (not longitudinally welded), having circular cross-sections, external diameter exceeds 406.4mm

HS code 730519 covers a specific type of iron or steel line pipe used in oil and gas pipelines. These large-diameter pipes play a crucial role in the global energy infrastructure, transporting vital resources across vast distances. As a key component of the energy supply chain, this industry is of significant economic importance, supporting various downstream industries and enabling the efficient distribution of oil and natural gas.

Production process

The production of 730519 line pipes typically involves a multi-step process. First, the raw materials, such as steel billets or coils, are heated and formed into the desired pipe shape using specialized machinery. The pipes may then undergo additional processing, such as heat treatment or coating, to enhance their durability and corrosion resistance. Quality control measures are implemented throughout the production process to ensure the pipes meet strict industry standards.

Production inputs

The main inputs required for the production of 730519 line pipes include high-quality steel, advanced manufacturing equipment, and specialized labor. Steel is the primary raw material, with specific grades and compositions selected to meet the performance requirements of oil and gas pipelines. Specialized machinery, such as rolling mills, welding equipment, and coating systems, are essential for the efficient and precise fabrication of these large-diameter pipes. Additionally, skilled workers with expertise in pipe manufacturing and quality control are crucial to the production process.

Production outputs

The primary output of HS code 730519 is large-diameter line pipes used in the oil and gas industry. These pipes are typically consumed by 460100 Oil and gas pipeline construction and 460200 Oil and gas pipeline operation industries, which rely on them to transport crude oil, natural gas, and other energy resources over long distances. The output of this industry may also be used in other applications, such as 460300 Water pipeline construction and 460400 Water pipeline operation, where large-diameter pipes are required for water distribution and infrastructure projects.
