Product Detail

321 Stainless Steel Pipe is available in a variety of shapes, sizes, grades, and finishes. The most common shapes are round tubes and pipes. The grades vary depending on your application; some grades are better suited for certain tasks than others.

321 Stainless Steel Pipes is used in many different industries due to its high strength-to-weight ratio and its ability to withstand extreme temperatures without compromising structural integrity. It is most commonly used in the oil & gas industry for pipelines that transport oil or gas through rough terrain or extreme temperatures. It also finds use in the automotive industry as exhaust systems due to its strong corrosion resistance properties as well as being aesthetically pleasing when polished correctly. Furthermore, stainless steel 321 is also found in chemical processing plants where it can resist corrosion from harsh chemicals that are often found there without sacrificing performance or reliability.

Applications of 321 Stainless Steel Pipe

• Oil and gas equipment
• Offshore technology
• Seawater desalination plants
• Chemical industry, especially when handling chlorides
• Flue-gas cleaning
• Pulp and paper industry
• Cargo tanks and pipe systems in chemical tankers
• Firewalls and blast walls on offshore platforms
• Bridges
• Storage tanks
• Pressure vessels, reactor tanks, and heat exchangers
• Rotors, impellers and shafts
