304 stainless steel flange has strong corrosion resistance. When using it, you need to pay attention to the connection method of construction, because 304 stainless steel flange becomes a stainless acid-resistant steel flange in steel structure applications. Its metal surface is smooth, It is not easy to oxidize with air, so it is often used in high-pressure water pipes and corroded pressure pipes. 304 stainless steel flanges have excellent performance.
The 304 stainless steel flange effectively prevents the further occurrence of oxidation reaction. However, other metal pipes, such as galvanized water pipes and copper pipes, have very little passivation ability, which is the key reason why the corrosion resistance of copper pipes of galvanized pipes is far inferior to that of stainless steel pipes. 304 stainless steel flange corrosion resistance performance, 304 stainless steel flange will not occur uniform corrosion like carbon steel.
304 stainless steel flange adopts 304 stainless steel flange water pipe, which has no restrictions on the chemical composition of water, because stainless steel has good corrosion resistance in water with various oxygen content, temperature, PH and hardness; stainless steel water pipe can withstand high The flow rate, even if the flow rate is greater than 40 m/s, still maintains an extremely low corrosion rate, not exceeding 0.003 mm/year, which is especially suitable for high-rise water supply.
The thermal expansion coefficient of 304 stainless steel flange pipe is similar to that of copper pipe, which is 1.5 times that of ordinary steel pipe. Compared with 304 stainless steel flange, 304 stainless steel flange pipe fittings have the characteristics of slow thermal expansion and cold contraction.
