Product Highlights
Excellent Corrosion Resistance
Stainless steel 304 contains approximately 18% chromium and 8% nickel, providing outstanding resistance against oxidation, corrosion, and many chemical environments.
High Dimensional Accuracy
ERW manufacturing technology ensures consistent outer diameter, wall thickness, straightness, and welding quality, making the pipes ideal for precision applications.
Smooth Internal and External Surface
Advanced forming and welding processes provide excellent surface finish, reducing friction loss and improving flow efficiency.
Cost-Effective Solution
Compared with seamless stainless steel pipes, ERW pipes provide competitive pricing while maintaining excellent performance for many industrial applications.
Manufacturing Process
Raw Material Inspection: Inspection of stainless steel coils to ensure chemical composition and surface quality.
Coil Slitting: Stainless steel coils are cut into suitable widths according to pipe specifications.
Tube Forming: The strip is gradually formed into a round tube through forming rollers.
ERW Welding: High-frequency electric resistance welding creates a strong and uniform welded seam.
Heat Treatment: Heat treatment improves mechanical properties and corrosion resistance.
Surface Treatment: Processes include annealing, pickling, polishing, or customized finishing.
Quality Inspection: Each pipe undergoes dimensional inspection, surface inspection, and testing before shipment.
