Elbow is a pipe fitting used to change the direction of the pipe in the piping system. According to the elbow Angle, 45° elbow, 90° elbow and 180° elbow are more commonly used. In addition, elbow manufacturers can also produce 60° elbow and other abnormal Angle elbow according to customer requirements and the actual needs of the project; According to the elbow production material, there are cast iron elbow, stainless steel elbow, alloy steel elbow, malleable cast iron elbow, carbon steel elbow, plastic elbow, among them, carbon steel elbow and stainless steel elbow is more widely used. So, do you know the difference between a carbon steel elbow and a stainless steel elbow? Is it just because of the material difference? Next, Ransheng pipeline will teach you the distinction between carbon steel elbow and stainless steel elbow.
To say the difference between carbon steel elbow and stainless steel elbow, we will certainly talk about their material is different, one is carbon steel, one is stainless steel. In fact, to put it bluntly, carbon steel elbow is an ordinary iron elbow, carbon steel elbow commonly processed materials are 20 #, A3, Q235, Q235A, Q235B and so on; The stainless steel elbow is on the basis of carbon steel added chromium Cr, nickel Ni, Mo and other alloy components, stainless steel elbow commonly used manufacturing materials are :304, 304L, 316, 316L, S30408, S30403, S31608, S31603 and so on.
The difference between carbon steel elbow and stainless steel elbow is that their performance characteristics are different, and the performance characteristics are different, the reason is because the material is different. Carbon steel elbow is an ordinary iron elbow, with good wear resistance and toughness, the production process is simple, reasonable comprehensive economy, applicable in many cases, but it is worth noting that carbon steel elbow easy to rust, so normally, carbon steel elbow welding after the need to do external paint anticorrosion treatment; And stainless steel elbow on the basis of carbon steel increased chromium Cr, nickel Ni, Mo and other alloy composition, its strength toughness index is stronger than carbon steel elbow, corrosion resistance, acid and alkali rust resistance, no need to use protective coating, stainless steel elbow connection after the pipeline leakage possibility is also relatively small.
Three of the differences between carbon steel elbows and stainless steel elbows is that their cleaning methods are different. Because of corrosion resistance and rust resistance of stainless steel elbows, stainless steel elbows need to be cleaned according to the requirements of the workpiece and the surface condition by alkali cleaning, water-soluble cleaning agent, chlorine solvent sandblasting, shot peening and other methods to clean, rather than using pickling method to clean.
Well, the above is the difference between carbon steel elbow and stainless steel elbow, I hope you can understand, and then choose the right type of elbow to use.
