Classification of Stainless Steel Pipe
✅ By Manufacturing Process
Seamless Pipes
No weld seam. High strength and pressure resistance. Best for high-temperature, high-pressure environments.Welded Pipes
Made by rolling and welding steel plates or coils. Cost-effective and suitable for general use.
✅ By Material Grade
304 / 304L – General-purpose stainless steel with good corrosion resistance.
316 / 316L – Excellent resistance to chloride and seawater corrosion.
2205 – Duplex stainless steel with high strength and superior stress corrosion resistance.
Other Grades – 309S, 310S, 410, 430 available upon request.
✅ By Shape
Round Pipes – Standard for fluid transport and structural use.
Square Pipes – Preferred in construction, machinery, and architecture.
Rectangular Pipes – Used in frames, furniture, and metalwork.
Custom Shapes – Available upon drawing or design.
