Stainless Steel Elbows Connect Two Large Diameter Pipe Fittings

Stainless Steel Weld Elbow joints may need to withstand high tensile, compressive, torsional, and shear strengths, and carbon steel elbows are a better choice. Stainless steel elbows will not corrode, pit, rust or wear. Stainless steel elbow manufacturer briefly introduces that stainless steel elbow is a connecting device for two large-diameter pipes.

Stainless steel elbow is a connecting device between two large-diameter pipes, usually two elbow pieces plus a number of fastening bolts. Carbon steel elbow is an elbow made of carbon steel. Low carbon steel has good plasticity and low strength. After adding excessive carbon elements, it will become stronger, and the plasticity will decrease and the strength will increase.

The corrosion resistance of stainless steel elbows depends on chromium, but because chromium is one of the components of steel, the protection methods are different.

When the added amount of chromium reaches 10.5%, the atmospheric corrosion resistance of the alloy elbow increases significantly. However, when the chromium content is higher, although the corrosion resistance can still be improved, it is not obvious. The reason is that alloying steel with chromium changes the type of surface oxide to one similar to that formed on pure chromium metal. This tightly adherent chromium-rich oxide protects the surface from further oxidation.

This oxide layer is extremely thin, and the natural luster of the stainless steel elbow surface can be seen through it, giving the stainless steel elbow a unique surface. Moreover, if the surface layer is damaged, the exposed steel surface will react with the atmosphere to repair itself, and re-form the oxide "passivation film" to continue to protect.
