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

HS v2017 Code: 730791

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

HS code 730791 covers a critical component in 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 construction and manufacturing.

Production process

The production of these iron or steel tube and pipe fittings typically involves a combination of casting, forging, and machining processes. Manufacturers may use techniques such as investment casting, sand casting, or die casting to create the initial fittings, followed by precision machining to ensure the desired dimensions, threads, and other features. Heat treatment and surface finishing processes may also be employed to enhance the fittings' strength, durability, and corrosion resistance.

Production inputs

The main inputs required for the production of HS code 730791 items include iron or steel raw materials, such as billets, bars, or sheets, as well as specialized machinery and tools for the casting, forging, and machining processes. Additionally, energy sources, such as electricity or natural gas, are necessary to power the production equipment, and skilled labor is required to operate the machinery and ensure quality control.

Production outputs

The primary outputs of HS code 730791 are various types of iron or steel tube and pipe fittings, including elbows, tees, couplings, unions, and flanges. These fittings are essential components in a wide range of industries, including 460110 Oil and gas, 251110 Construction, 281110 Chemical manufacturing, and 281210 Plastics and rubber manufacturing, where they are used to connect and secure piping systems for the transportation of fluids, gases, and other materials.
