Core Product Advantages

High-Temperature Performance: A321H material with titanium stabilization, excellent creep resistance at high temperature (≤870℃), no deformation after long-term service in heat exchangers and boilers.
Corrosion Resistance: Bright annealed + passivation double protection, strong resistance to intergranular corrosion and medium corrosion, adaptable to various industrial harsh environments.
Dimensional Precision: Strictly in line with ASTM A213 standard, precise OD/WT tolerance, smooth tube wall, good interchangeability, reducing assembly difficulty and improving work efficiency.
Hygienic & Easy Maintenance: BA surface is oil-free, dust-free and smooth, no dirt accumulation, easy to clean, meeting industrial hygienic requirements for fluid transfer.
Durability: Seamless production process, uniform structure, high tensile strength and toughness, not easy to burst or leak, long service life and low maintenance cost.
Versatility: Widely used in heat exchangers, boilers, condensers and high-temperature chemical processing, supporting customization of specifications and shapes to meet diverse needs.
