HS v2022 Code: 730793

About iron or steel; tube or pipe fittings, butt welding fittings, other than stainless steel

HS code 730793 covers a crucial component of the global industrial and infrastructure landscape - iron or steel tube and pipe fittings, specifically butt welding fittings that are not made of stainless steel. These fittings play a vital role in connecting and joining pipes and tubes, enabling the efficient transportation of fluids, gases, and other materials across a wide range of industries, from oil and gas to water and wastewater management, and construction.

Production process

The production of these fittings typically involves a combination of metalworking techniques, including stamping, forging, and welding. Manufacturers use specialized machinery and tools to shape the raw steel or iron materials into the desired fitting shapes, ensuring precise dimensions and tight tolerances. The butt welding process is a critical step, where the fittings are joined together seamlessly to create a strong, durable connection.

Production inputs

The primary inputs for the production of HS code 730793 fittings are high-quality steel or iron raw materials, often sourced from 720810 Iron and non-alloy steel in ingots or other primary forms and 720711 Semi-finished products of iron or non-alloy steel. Manufacturers also require specialized welding equipment, cutting tools, and other metalworking machinery to shape and assemble the fittings. Skilled labor, including welders, machinists, and quality control personnel, is another essential input for this industry.

Production outputs

The primary output of HS code 730793 is a diverse range of iron or steel tube and pipe fittings, including elbows, tees, reducers, and other butt welding fittings. These fittings are then consumed by a variety of downstream industries, such as 730110 Line pipe of a kind used for oil or gas pipelines, 730120 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, and 730300 Tubes, pipes and hollow profiles, of cast iron, as well as the broader construction and infrastructure sectors.
