Water industry: Stainless steel is the best material for water preparation, storage, transportation, purification, regeneration, desalination and other water industries. Its advantages are corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), and light weight ( Reduced 1/ 3), less maintenance, long life (can be used for 40 years), low life cycle cost (LCC), etc., and it is a green and environmentally friendly material that can be recycled and reused. At present, the pipeline stainless steel in Tokyo, Japan has reached 76%, the water leakage rate of the pipeline has dropped from 14.7% to 7.5%, and the corrugated pipe joint has been developed recently, which has reduced the construction cost of stainless steel water pipeline by 20% and the total cost %, the maintenance cost is reduced by 3/4.
