Stainless steel pipes and tubes have superior corrosion resistance, heat resistance, and low - temperature properties, and have been used as raw materials that can withstand harsh environments as seen in various fields. Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of application, like petrochemical, chemical engineering, natural gas and liquefied natural gas, food and sanitary, paper-making, heat ex-changer, seawater desalination, decoration area, etc.
