321 Cold Rolled Stainless Steel Strip For Gas Pipe

Application scenarios
• Industrial gas system: In factories, workshops and other places where industrial gas (such as propane and natural gas) is used and the ambient temperature is high, 321 stainless steel gas pipes can withstand high temperature radiation during equipment operation to ensure stable gas delivery.
• High temperature environment gas connection: For example, gas connection pipes near ovens and boilers in the kitchen, or in laboratories, catering kitchens and other scenes with continuous temperature fluctuations, use its high temperature resistance to extend the service life of the pipeline.
• Scenarios with basic requirements for corrosion resistance: Compared with ordinary carbon steel gas pipes, 321 stainless steel gas pipes can better cope with humid environments or trace corrosive components in gas, reducing safety hazards caused by rust.

Differences from common gas pipes
• Compared with galvanized steel pipes: 321 stainless steel gas pipes have better corrosion resistance and high temperature resistance, but the cost is higher and suitable for special environments.
• Compared with 304 stainless steel gas pipes: 321 has stronger resistance to intergranular corrosion at high temperatures and is more reliable in environments above 500°C for a long time, while 304 has corrosion resistance at room temperature that can meet most civilian scenarios and has lower costs.

In general, 321 stainless steel gas pipes are not the mainstream choice for gas transportation. They are more used in niche scenarios with special requirements for high temperature resistance and intergranular corrosion resistance. Daily civil gas pipelines are still mainly galvanized steel pipes, 304 stainless steel pipes or plastic composite pipes.
