Stainless steel is a versatile material made up of a steel alloy with a trace of chromium added to it. The inclusion of chromium improves the material's corrosion resistance, which is why it's known as chrome steel.
Stainless Steel Pipes with various Grades include seamless and welded stainless steel pressure pipes, electric fusion welded (EFW) pipes for high-pressure applications, large-diameter welded pipes for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipes.
What is EFW Pipe?
Electron beam welding is referred to as Electric Fusion Welding (EFW) steel pipe. It refers to how the pipes are made. In the EFW manufacturing process, welded pipes are created by hot or cold rolling plates and seam welding. Such EFW pipes are developed following international quality standards to reach the greatest degree of quality.
What is SS 321 EFW Pipe?
SS Grade 321 EFW Pipes are a high-carbon 321 Alloy version developed for exceptional strength at high temperatures. All applications for stainless steel SS Grade 321 EFW Pipes are in the temperature range of roughly 900o C, with high strength, phase stability, and scaling resistance, as well as resistance to subsequent aqueous corrosion.
EFW 321 A358 Pipes are put through a series of tests to determine their strength, durability, temperature resistance, and other factors.
Pipes are composed of stainless steel 321 with titanium stabilization to avoid chromium carbide production.
Because they are non-responsive to inter-granular corrosion after heating in the carbide precipitation range of 425 C to 850 C, stainless steel ASTM A358 TP 321 EFW pipes are utilized. Welded Pipes A358 GR. TP 321 EFW is well-known for its great quality and durability. These pipes are made of austenitic stainless steel. Titanium is also utilized to help these pipes stay stable.
Crept resistance is another advantage of SS 321 EFW Pipes. These EFW Welded Pipes are capable of resisting intergranular corrosion even after being exposed to temperatures in the chromium carbide precipitation range.
321 EFW Pipes are austenitic chromium-nickel stainless steel pipes that have been electric-fusion welded and are appropriate for corrosive or high-temperature usage, or both, as well as general applications. Oil and gas, petroleum, petrochemical, chemical, machine construction, and automobile sectors, among others, utilize 321 Stainless Steel EFW Pipes.
