hick-walled large-diameter seamless steel pipes excel in superior high-pressure resistance, strong structural stability, adaptability to harsh conditions, and long-term durability.

Hot-Rolled Coil (HRC) is a foundational, high-demand steel product. It’s made by heating steel slabs to 1100-1250℃ (above steel’s recrystallization temperature), rolling them continuously, and coiling the finished sheet.

HDG (Hot-Dip Galvanizing) and TDG (Thermal Diffusion Galvanizing) pipes both offer corrosion resistance, but differ in core process and performance:
