As to the different application, we can choose different metal material for the metal corrugated pipe culvert. There are three materials for the metal cprrugated pipe culvert, stainless steel, tin bronze, beryllium bronze. Austenitic stainless steel corrugated pipe culvert are always used as the isolation medium or the sealing element because of its excellent mechanical property and anti-corrosion performance. The metal corrugated pipe culvert with the tin bronze has a certain elasticity, fine processing property, high fatigue strength. Which is usually used in the instrument application. Beryllium bronze can be used in the high requirement occasion for its fine performance. Besides those common material, there are constant elastic alloy, high temperature alloy.
