[0002] Stainless steel joints are a type of equipment made of stainless steel and used to connect pipes. They can connect pipes of different diameters and shapes to ensure the continuity and integrity of the pipeline system. They are widely used in many industries such as construction, machinery, and chemical industry.

[0003] Most of the stainless steel joints are made by a casting process.
