About steel, alloy; tubes, pipes and hollow profiles (other than stainless steel or seamless), welded, of circular cross-section, n.e.c. in chapter 73

HS code 730650 covers a crucial segment of the steel industry, focusing on the production of welded, circular cross-section steel tubes, pipes, and hollow profiles. These products are widely used in a variety of industries, including construction, manufacturing, and infrastructure development, making them an essential component of the global economy.

Production process

The production of steel tubes and pipes under HS code 730650 typically involves a welding process. Steel coils or sheets are first cut to the desired size and shape, then formed into a cylindrical shape and welded along the seam. This process can be carried out using various welding techniques, such as electric resistance welding (ERW) or submerged arc welding (SAW), depending on the specific requirements of the product.

Production inputs

The main inputs required for the production of steel tubes and pipes under HS code 730650 include steel coils or sheets, which serve as the raw material. Additionally, specialized machinery, such as tube-forming and welding equipment, is necessary for the manufacturing process. Other inputs may include various consumables, such as welding electrodes, shielding gases, and lubricants, as well as energy sources like electricity or natural gas.

Production outputs

The primary output of the industry covered by HS code 730650 is welded, circular cross-section steel tubes, pipes, and hollow profiles. These products are then consumed by a wide range of industries, including 730410 Steel, stainless; line pipe of a kind used for oil or gas pipelines, 730429 Steel, stainless; casing and tubing of a kind used in drilling for oil or gas, 730630 Steel, other than stainless; other tubes, pipes and hollow profiles, welded, of circular cross-section, of iron or non-alloy steel, and 730661 Steel, alloy; tubes and pipes, welded, of circular cross-section, of stainless steel.
