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 stainless steel line pipe typically involves a welding process. Steel coils or sheets are cut to size, formed into a cylindrical shape, and then welded along the seam to create a seamless pipe. The welding process can be performed using various techniques, such as submerged arc welding or electric resistance welding, depending on the specific requirements of the application.

Production inputs

The main inputs required for the production of 730611 stainless steel line pipe include high-quality stainless steel raw materials, such as 720810 hot-rolled coils, 720920 cold-rolled coils, or 721070 stainless steel plates. Additionally, specialized welding equipment, such as welding machines and consumables, are essential for the manufacturing process. Other inputs may include various tools, machinery, and energy sources required for the pipe-forming and welding operations.

Production outputs

The primary output of HS code 730611 is stainless steel line pipe used in oil and gas pipelines. These pipes are often consumed by companies involved in the 271000 petroleum and natural gas industry, as well as 230990 other miscellaneous food preparation and manufacturing, 281410 anhydrous ammonia, and 281511 (sodium hydroxide (caustic soda)) industries, which may require specialized pipeline infrastructure for their operations.
