We supply high-quality large-diameter stainless steel round tubes for industrial use. OEM/ODM customization, seamless or welded, available in 304, 316L, 310S, and other grades. Trusted manufacturer with global delivery.
Our large-diameter stainless steel round tubes are engineered for heavy-duty industrial applications that require strength, corrosion resistance, and long-term durability. As an experienced OEM & ODM manufacturer in China, we specialize in producing custom-size stainless steel round tubes with diameters ranging from 89mm to over 600mm. Our tubes are widely used in industries such as petrochemical, construction, marine, energy, and machinery.
Manufactured using high-grade austenitic, ferritic, or duplex stainless steels (e.g., 304, 316L, 321, 310S, 2205), our large-diameter tubes feature excellent weldability, pressure resistance, and surface finishes (pickled, polished, or brushed). We support full customization including wall thickness, length, end treatments, and surface finish per client specifications.
