Iron or steel (excluding cast iron or stainless steel); seamless, line pipe of a kind used for oil or gas pipelines

HS v2017 Code: 730419

About iron or steel (excluding cast iron or stainless steel); seamless, line pipe of a kind used for oil or gas pipelines

HS code 730419 covers a critical component of the global energy infrastructure - seamless steel pipes used in oil and gas pipelines. These pipes play a vital role in the transportation of hydrocarbons from production sites to refineries and distribution networks. The demand for these specialized pipes is closely tied to the exploration, extraction, and distribution activities of the oil and gas industry, which is a major driver of economic growth worldwide.

Production process

The production of seamless steel pipes for oil and gas pipelines involves a complex manufacturing process. It typically begins with the heating and piercing of solid steel billets to create a hollow shell. This shell is then repeatedly rolled and drawn through a series of dies to reduce the wall thickness and increase the length, resulting in a seamless pipe. Advanced techniques like electric resistance welding may also be employed to enhance the pipe's structural integrity and performance characteristics.

Production inputs

The key inputs for the production of HS code 730419 pipes include high-quality steel, specialized rolling and drawing equipment, and advanced welding technologies. Steel suppliers must meet stringent quality standards to ensure the pipes can withstand the high pressures and corrosive environments encountered in oil and gas pipelines. Additionally, the manufacturing process requires significant capital investment in specialized production facilities and skilled labor.

Production outputs

The primary output of HS code 730419 is seamless steel pipes used in the construction and maintenance of oil and gas pipelines. These pipes are essential for the transportation of crude oil, natural gas, and refined petroleum products over long distances. The output of this industry is consumed by 460100 Oil and gas pipeline and related structures construction and 351110 Petroleum refineries.
