Stainless Steel Pipes: Types & Classifications Stainless steel pipes are primarily categorized by manufacturing process and surface finish: By Manufacturing Process: Seamless stainless steel pipes Welded stainless steel pipes By Surface Finish: Ordinary stainless steel pipes Matte stainless steel pipes Bright stainless steel pipes Stainless Steel Pipe Fittings Stainless steel pipe fittings are components used to connect pipes into a complete piping system. They are classified by connection method and functional type: 1. Classification by Connection Method Socket weld stainless steel fittings Threaded stainless steel fittings Flange stainless steel fittings Welded stainless steel fittings 2. Common Functional Types & Applications Elbows: Used at pipe bends to change the direction of fluid flow. Tees: Used at the junction of three pipes (for flow splitting or combining). Crosses: Used at the junction of four pipes (for multi-way flow distribution). Reducers: Used to connect two pipes of different diameters, ensuring smooth fluid transition. Caps: Used to seal the end of a pipe. 3. Common Materials The primary stainless steel grades used for pipes and fittings include: 304, 304L, 316, and 316L.
