Stainless steel pipes with plain ends have a smooth surface without any modifications or attachments. Plain end pipes are typically used in applications where the pipe needs to be joined using welding techniques or other specialized connection methods. They are commonly found in industrial piping systems, construction projects, and infrastructure applications where welding or coupling is the preferred method of connection.

Threaded stainless steel pipes feature ends with external or internal threads, allowing for easy and secure connections using compatible fittings such as couplings, elbows, or valves. Threaded ends provide a convenient method for assembling and disassembling pipe sections without the need for welding or specialized tools. They are commonly used in plumbing systems, gas distribution networks, and applications that require frequent maintenance or disassembly.

Beveled stainless steel pipes have angled end surfaces, typically at a 30° or 45° bevel, which facilitates proper welding joint preparation. The beveled end ensures smooth and precise alignment during welding, promoting strong and reliable connections. These pipes are commonly used in industries such as oil and gas, petrochemicals, and construction, where welded joints need to withstand high pressure or corrosive environments.

Flanged stainless steel pipes feature raised flanges at the ends, providing a robust and secure method of connection using flange fittings. Flanged ends are widely used in piping systems that require easy disassembly or where the pipes need to be connected to other equipment or components, such as pumps, valves, or tanks. Industries that commonly utilize flanged end pipes include chemical processing, oil refineries, and power generation.
