HS v2022 Code: 730519

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 pipeline infrastructure. These large-diameter pipes play a crucial role in the global energy industry, facilitating the transportation of oil, natural gas, and other hydrocarbons over long distances. The demand for these pipes is closely tied to the exploration, production, and distribution activities of the oil and gas sector, making this industry an integral part of the broader energy economy.

Production process

The production of 730519 line pipes typically involves a multi-step manufacturing process. The raw materials, which include steel billets or coils, are first heated and then formed into the desired pipe shape through processes such as rolling, bending, or welding. Depending on the specific requirements, the pipes may undergo additional treatments like heat treatment, coating, or testing to ensure their structural integrity and suitability for use in high-pressure pipeline systems.

Production inputs

The main inputs required for the production of 730519 line pipes include steel raw materials, such as 720610 Iron and non-alloy steel in ingots or other primary forms, 720711 Semi-finished products of iron or non-alloy steel, or 720810 Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated. Additionally, specialized machinery and equipment, such as rolling mills, welding machines, and testing apparatus, are essential for the manufacturing process.

Production outputs

The primary output of HS code 730519 is large-diameter line pipes used in oil and gas pipeline infrastructure. These pipes are typically consumed by industries involved in the 270000 Mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes sector, such as 271000 Petroleum oils and oils obtained from bituminous minerals, other than crude; preparations n.e.c., containing by weight 70% or more of petroleum oils or of oils obtained from bituminous minerals; these being the basic constituents of the preparations; waste oils and 271600 Electrical energy.
