Overview of Stainless Steel Stub End
A stainless steel stub end is a type of pipe fitting used in conjunction with a lap joint flange to create a flanged connection in a piping system. It consists of a short section of pipe with one end flared or machined to match the dimensions of the lap joint flange, while the other end is prepared for welding to the pipe.
Stainless Steel Stub End Mill Test Certificate
Stainless steel stub end generally constructed from stainless steel (common grades include 304,316L,904L),and also nickel alloy like inconel 625,inconel 600,monel 400,C276,offering excellent resistance to rust, corrosion, and high temperatures.
Manufacturing Processing of SS Fittings
- Material Selection: High-quality stainless steel is chosen based on application requirements.
- Forming: The caps are formed using methods like stamping, deep drawing, or spinning to achieve the desired shape (domed, flat, etc.).
- Machining: For threaded caps, threads are cut or machined into the fitting.
- Welding: For socket weld or butt weld caps, welding is performed to ensure a secure and leak-proof seal.
- Surface Finishing: The caps are polished, brushed, or passivated to enhance corrosion resistance and meet hygiene standards.
- Quality Inspection: Rigorous testing, including dimensional checks, visual inspection, and pressure testing, ensures the caps meet industry standards.
