Stainless Pipe 

Stainless steel pipes are pipes made from a steel alloy that contains chromium, nickel, and other elements that make them resistant to corrosion, oxidation, and high temperatures. They are often used in industrial processes and applications to carry substances like oil, natural gas, water, and steam. 

Here are some characteristics of stainless steel pipes:

• Corrosion resistance: Stainless steel pipes are naturally resistant to corrosion, but they can still rust if exposed to damaging chemicals, heat, moisture, grease, or saline for extended periods of time. 

• Durability: Stainless steel pipes are durable and hard wearing. 

• Maintenance: Stainless steel pipes are easy to maintain. 

• Recyclable: Stainless steel pipes are recyclable and environmentally friendly. 

• Fabrication: Stainless steel pipes can be formed into various shapes, bends, and curves. 

• Grades: Stainless steel pipes come in various grades, each with its own unique composition and characteristics. The most common grades used for piping are 304 and 316. 

• Manufacturing: Stainless steel pipes are commonly manufactured using a welding process or extrusion. 

To identify if a pipe is stainless steel, you can remove the oxide layer on the steel, put a drop of water on it, and rub it with copper sulfate. If it doesn't change color after rubbing, it's usually stainless steel.
