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 range of iron or steel line pipes used in the oil and gas pipeline industry. These pipes play a crucial role in the transportation of energy resources, connecting production sites to refineries, storage facilities, and distribution networks. As a key component of critical infrastructure, the demand for these pipes is closely tied to global energy consumption and investment in pipeline projects.

Production process

The production of line pipes under HS code 730619 typically involves a combination of rolling, welding, and finishing processes. Steel billets or coils are first rolled into the desired pipe dimensions, with the seam then welded using techniques such as electric resistance welding or submerged arc welding. The pipes may undergo additional finishing steps, such as heat treatment, coating, or threading, to meet specific performance requirements and industry standards.

Production inputs

The main inputs for the production of 730619 line pipes include steel raw materials, such as hot-rolled coils or plates, as well as various consumables like welding electrodes, protective coatings, and specialized machinery. The quality and properties of the steel used, such as its strength, corrosion resistance, and weldability, are crucial factors in determining the performance of the final product.

Production outputs

The primary output of HS code 730619 is line pipes used in the oil and gas industry for the transportation of energy resources. These pipes may be consumed by 460110 Pipeline transport operators, 351110 Petroleum refineries, and other 351120 Natural gas processing plants that require reliable and durable pipeline infrastructure. The specific dimensions, material specifications, and end-use applications of these line pipes can vary depending on the project requirements and industry standards.
