Stainless steel and Ni-based alloy pipes and tubes exhibit exceptional corrosion resistance, heat resistance, and low-temperature performance, making them ideal for harsh environments in petroleum refining, petrochemicals, and energy sectors like power and gas. Their durability and reliability have also led to increased use in building construction due to their aesthetic appeal. Additionally, they are now widely adopted in high-cleanliness applications, such as semiconductor and liquid-crystal manufacturing equipment, where stringent cleanliness standards are essential.
