Steel, stainless; tube or pipe fittings, threaded elbows, bends and sleeves

HS v2022 Code: 730722

About steel, stainless; tube or pipe fittings, threaded elbows, bends and sleeves

HS code 730722 covers the import and export of stainless steel tube or pipe fittings, including threaded elbows, bends, and sleeves. These components are essential in a wide range of industries, from construction and plumbing to manufacturing and transportation. As a crucial part of piping systems, the global demand for these fittings continues to grow, driven by factors such as infrastructure development, industrial expansion, and the need for durable, corrosion-resistant materials.

Production process

Stainless steel tube or pipe fittings are typically produced through a combination of casting, forging, and machining processes. The raw stainless steel is first melted and cast into the desired shape, often using precision molds. The cast components are then subjected to forging or rolling to refine the microstructure and improve mechanical properties. Finally, the fittings undergo various machining operations, such as threading, drilling, and finishing, to achieve the required dimensions and surface finish.

Production inputs

The primary inputs for the production of HS code 730722 items include high-quality stainless steel alloys, which provide the necessary corrosion resistance and mechanical strength. Additionally, specialized machinery, such as casting equipment, forging presses, and CNC machining centers, are required to manufacture these fittings efficiently and to the desired specifications. Other inputs may include lubricants, cutting tools, and various consumables used in the production process.

Production outputs

The main outputs of HS code 730722 are stainless steel tube or pipe fittings, including threaded elbows, bends, and sleeves. These components are widely used in a variety of industries, such as 730610 Steel, stainless; line pipe of a kind used for oil or gas pipelines, 730630 Steel, stainless; other tubes, pipes and hollow profiles, welded, of circular cross-section, and 842139 Machinery and apparatus for filtering or purifying gases, n.e.c. in item no. 8421.39.
