How to Choose Stainless Steel Seamless Pipe or Welded Pipe
How to Choose Stainless Steel Seamless Pipe or Welded Pipe?
Based on the characteristics and differences of stainless steel seamless pipes and stainless steel welded pipes, reasonable choices should be made during application to achieve economic, beautiful and reliable effects:
1. When used as decorative pipes, product pipes, and prop pipes, they generally require good surface effects, and stainless steel welded pipes are usually used;
2. For generally lower pressure fluid transportation, such as low pressure systems such as water, oil, gas, air, and heating water or steam, stainless steel welded pipes are usually used
3. For pipelines used in industrial engineering and large-scale equipment to transport fluids, as well as pipelines that require high temperature, high pressure, and high strength on power plants and nuclear power plant boilers, stainless steel seamless pipes should be used;
4. Stainless steel welded pipes are generally used for liquid transportation below 0.8MPa, and seamless pipes can be used for liquid transportation above 0.8MPa. If the pressure requirement is not high, it will be more economical to use welded pipe.
