About steel; stainless; line pipe of a kind used for oil or gas pipelines n.e.c. in chapter 73, welded, (not seamless)

HS code 730611 covers stainless steel line pipe used in oil and gas pipelines. This type of pipe is essential for the transportation of energy resources, playing a crucial role in the global energy infrastructure. The demand for 730611 line pipe is closely tied to the exploration, production, and distribution activities of the oil and gas industry, making it an important component of the broader energy sector.

Production process

The production of 730611 line pipe involves a multi-step welding process. Stainless steel coils or sheets are first cut to the desired size and shape. The edges are then carefully aligned and welded together using advanced techniques such as submerged arc welding or gas tungsten arc welding. The welded pipe is then subjected to heat treatment and other finishing processes to ensure its strength, durability, and corrosion resistance.

Production inputs

The main inputs required for the production of 730611 line pipe include high-quality stainless steel, welding consumables, and specialized machinery. Stainless steel grades such as 72111 Stainless steel; flat-rolled products, width >= 600mm, not further worked than hot-rolled and 72122 (Stainless steel; flat-rolled products, width >= 600mm, not further worked than cold-rolled (cold-reduced)) are commonly used. Additionally, the production process requires welding equipment, pipe-forming machinery, and various tools and accessories.

Production outputs

The primary output of HS code 730611 is stainless steel line pipe used in oil and gas pipelines. These pipes are typically consumed by the 2711 Natural gas; liquefied or in the gaseous state and 2709 Petroleum oils and oils obtained from bituminous minerals, crude industries, as they are essential for the transportation of these energy resources. The 730611 line pipe may also be used in other applications, such as 8430 Machinery for moving, grading, levelling, scraping, excavating, tamping, compacting, extracting or boring earth, minerals or ores; pile-drivers and pile-extractors; snow-ploughs and snow-blowers and 8431 Parts suitable for use solely or principally with the machinery of headings 84.25 to 84.30.
