About iron or steel (excluding cast iron); line pipe of a kind used for oil or gas pipelines (other than of stainless steel or seamless), n.e.c. in chapter 73
HS code 730619 covers a critical component of the global energy infrastructure - line pipe used for oil and gas pipelines. These steel pipes play a vital role in the transportation of vital fossil fuels, connecting production sites to refineries, storage facilities, and distribution networks. As the world's energy demands continue to grow, the importance of this industry in facilitating the efficient and reliable movement of oil and natural gas cannot be overstated.
Production process
Line pipes classified under HS 730619 are typically produced using a combination of rolling, welding, and finishing techniques. The manufacturing process often begins with the procurement of steel coils or plates, which are then cut, formed, and welded into the desired pipe dimensions. Advanced techniques such as electric resistance welding (ERW) or submerged arc welding (SAW) may be employed to ensure the integrity and strength of the final product.
Production inputs
The primary inputs for the production of line pipes under HS 730619 include steel raw materials, such as coils or plates, as well as specialized machinery for cutting, forming, and welding the pipes. Additional inputs may include various consumables like welding electrodes, protective coatings, and testing equipment to ensure the pipes meet industry standards and specifications. The availability and quality of these inputs are crucial to the overall productivity and competitiveness of this industry.
Production outputs
The primary output of HS 730619 is line pipe used for the transportation of oil and natural gas. These pipes are essential components in the construction and maintenance of pipelines that connect production sites to refineries, storage facilities, and distribution networks. The output of this industry may also be consumed by other related industries, such as 730630 Steel pipe, seamless, of a kind used for oil or gas pipelines, 730640 Steel pipe, welded, of a kind used for oil or gas pipelines, and 730650 Other steel tubes, pipes and hollow profiles, welded, of circular cross-section, of a kind used for oil or gas pipelines.
