The advantage of stainless steel elbow material is that it has good corrosion resistance, which makes it an ideal choice for all kinds of pipes. Since stainless steel can be passivated by oxidants, a tough and dense chromium-rich oxide outer coating Dr2O3 is formed on the surface, which can effectively prevent further oxidation reactions. This is the reason why galvanized pipes have much lower corrosion resistance than stainless steel pipes, because other metal pipes (such as galvanized water and copper pipes) have very little passivation ability.

The stainless steel elbow material will not corrode uniformly like carbon steel, and does not require a protective coating during use. Using stainless steel, the oxygen content, temperature, pH and hardness in the water are uniform, so there is no restriction on the chemical composition of the water. It has excellent corrosion resistance. Stainless steel water pipes can enjoy a higher flow rate even at a flow rate of more than 40 m/s, but the corrosion rate is very low, not exceeding 0.003 mm per year. Especially suitable for watering buildings.

When storing the stainless steel elbow material, take care to avoid rain and impurities from entering. Rainwater and pollutants need to be wiped differently according to their nature. Stainless steel elbow should be checked regularly after storage. If there is rust, remove the rust layer. Under normal circumstances, oil is not required after cleaning the surface of the stainless steel elbow, but for high-quality steel, alloy steel plate, thin-walled elbows and alloy steel elbows, after derusting, they must be removed before storage. The inner and outer surfaces of the elbow must be coated with anti-rust oil. If your elbow is severely corroded, it is not suitable for long-term storage after rust removal and should be used as soon as possible.
