Iron or steel; tube or pipe fittings, flanges, other than stainless steel

HS v2022 Code: 730791

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

HS code 730791 covers a critical component of the global industrial and infrastructure landscape - iron or steel tube and pipe fittings, excluding those made of stainless steel. These fittings play a vital role in connecting and securing various piping systems, 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. As a fundamental building block of modern industrial and construction projects, the demand for these fittings remains strong, making this a significant sector within the broader metal products industry.

Production process

The production of iron or steel tube and pipe fittings, as described by HS code 730791, typically involves a combination of casting, forging, and machining processes. Manufacturers may start with raw materials such as iron or steel billets, which are then heated and formed into the desired shapes and sizes using specialized equipment. Precision machining is often employed to ensure the fittings meet strict dimensional and quality standards, enabling them to withstand the rigors of industrial applications.

Production inputs

The main inputs required for the production of iron or steel tube and pipe fittings under HS code 730791 include iron or steel raw materials, such as billets, bars, and sheets. Additionally, manufacturers rely on specialized machinery and tools, including casting equipment, forging presses, and CNC machining centers, to shape and finish the fittings. Energy sources, such as electricity or natural gas, are also essential for powering the production processes.

Production outputs

The primary output of the industry covered by HS code 730791 is a diverse range of iron or steel tube and pipe fittings, including flanges, elbows, tees, and other connection components. These fittings are then consumed by a variety of downstream industries, such as 460110 Oil and gas, 421110 Water supply, 422210 Sewerage, and 230110 Construction, where they are used to assemble and maintain critical infrastructure and industrial systems.
