Galvanized Pipe / Seamless & Welded Galvanized Pipe
Material:
Carbon Steel: Q195, Q215, Q235, SPHC, SPHD, SPHE etc.
Selection Recommendations:
Corrosion resistance: Zinc-aluminum alloy plating (e.g. Galfan) is recommended for coastal areas.
Welding: Mild steel (Q195-Q235) is easier to weld.
Cost: Ordinary carbon steel + hot-dip galvanizing is the most cost-effective.
(1) Welded Steel Pipe (ERW/SSAW): Raw materials: hot-rolled or cold-rolled steel coils. Flow: Uncoiling → leveling → high-frequency welding (HFW) → sizing → cutting.
(2) Seamless Pipe: Raw material: round billet. Flow: Billet heating → punching → hot rolling/cold drawing → straightening.
