One key difference between seamless and EFW stainless steel pipes is their manufacturing complexity. Seamless pipes require more intricate and precise manufacturing techniques, resulting in a higher production cost compared to EFW pipes. Additionally, the seamless process allows for a wider range of sizes and thicknesses, while EFW pipes are typically limited in their size options. Another difference lies in the availability of grades and alloys. Seamless stainless steel pipes are available in a wide range of grades and alloys, offering greater flexibility for specific applications. EFW pipes, on the other hand, have a more limited selection of available grades and alloys. In terms of mechanical properties, seamless stainless steel pipes generally have superior strength and corrosion resistance compared to EFW pipes. The absence of welds or joints in seamless pipes reduces the risk of weak points that could be prone to corrosion or failure. In summary, seamless stainless steel pipes are manufactured without any welding seams, offering better strength, durability, and corrosion resistance. They are suitable for high-pressure, high-temperature, or corrosive applications. EFW stainless steel pipes, on the other hand, are created by fusion welding two stainless steel sheets or plates together, making them more suitable for lower-pressure and lower-temperature applications.
