HS v2017 Code: 730721

About steel, stainless; tube or pipe fittings, flanges, of stainless steel

HS code 730721 covers the import and export of stainless steel tube or pipe fittings and flanges. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential components for a wide range of applications. Stainless steel fittings and flanges are valued for their durability, corrosion resistance, and ability to withstand high temperatures and pressures, making them indispensable in industries such as oil and gas, chemical processing, and water treatment.

Production process

The production of stainless steel tube or pipe fittings and flanges typically involves a series of metalworking processes. This includes cutting, bending, welding, and finishing operations to shape the stainless steel into the desired fittings and flanges. Advanced manufacturing techniques, such as computer numerical control (CNC) machining, may be employed to ensure precision and consistency in the final products.

Production inputs

The main inputs required for the production of stainless steel tube or pipe fittings and flanges include high-quality stainless steel raw materials, specialized metalworking machinery, and skilled labor. Stainless steel grades, such as 72241000 Stainless steel, bars and rods, hot-rolled, in irregularly wound coils, are commonly used as the primary raw material. Additionally, various tools, jigs, and fixtures are necessary to facilitate the manufacturing process.

Production outputs

The primary outputs of this industry are stainless steel tube or pipe fittings and flanges, which are used in a wide range of applications. These components are often consumed by industries such as 84212300 Filtering or purifying machinery and apparatus for liquids, 84213100 Intake air filters for internal combustion engines, and 84219900 Parts of filtering or purifying machinery and apparatus for liquids or gases, where their durability and corrosion resistance are highly valued.
