Spiral Welded Pipe vs. Other Pipe Types: A Detailed Comparison

Choosing the right type of الفولاذ pipe depends on cost, strength, applications, and durability. Below is a comparison of spiral welded pipes (SSAW), longitudinal welded pipes (LSAW), and electric resistance welded pipes (ERW):

الميزة	Spiral Welded Pipe (SSAW)	Longitudinal Welded Pipe (LSAW)	Electric Resistance Welded Pipe (ERW)
عملية التصنيع	Spiral welding from steel coils	Straight seam welding from steel plates	High-frequency electric resistance welding
Best For	Oil & gas pipelines, water transmission, piling	Large-diameter pipelines, heavy-duty applications	Structural and mechanical applications
نطاق القطر	Φ219-Φ3500 مم	Φ406–Φ1422mm	Φ21–Φ660mm
سُمك الجدار	6–26mm	8–40mm	1.5–16mm
Strength & Durability	High, but slightly weaker than LSAW	Stronger weld seam compared to SSAW	Lower strength, suitable for smaller diameters
الفعالية من حيث التكلفة	Lower cost due to efficient production	Higher cost due to plate welding	Most affordable but limited in strength
مقاومة التآكل	Can be coated with 3LPE, FBE, etc.	Can be coated with 3LPE, FBE, etc.	Limited corrosion resistance

Which Pipe is Best for Your Project?

✔ For large-diameter, long-distance pipelines → Choose SSAW or LSAW
