The difference between pipe bend and pipe elbow

　　Pipe elbows and pipe bends are fittings used to change the direction of pipes. ASME B16.9 Carbon Steel Pipe Fitting 5D Bend and pipe elbow have been widely used in construction. However, in actual use, the performance of pipe bend and pipe elbow is different.

　　Pipe bend is a pipe fitting, a common pipe fitting that is usually manufactured to specific needs. The length is much longer than the pipe elbow. Although they are both pipe fittings that change the direction of pipes, there are many differences between them.

　　1. Different manufacturing processes

　　There are significant differences in the production process between carbon steel pipe bend and elbows. During the manufacturing process of pipe bend, pipe bend can be used for cold bending. Then bend it directly with a pipe bender. The elbow can be manufactured in one go without secondary corrosion protection, but the manufacturer needs to customize the elbow, which requires corrosion resistance and long service life.

　　2. Prices are different

　　Carbon steel pipe bend cost less than elbows, but can be easily damaged without corrosion protection. However, due to its low price, it has been widely used in some less demanding projects.

　　3. Different bending radii

　　The bending radius of the carbon steel pipe bend is usually larger than that of the pipe elbow; the mechanical strength per unit area of the elbow is usually larger than that of the pipe elbow. You can choose according to your needs during use. For example, to cope with the erosion of pipeline fluid at corners, thick-walled elbows can be selected to resist erosion; large-radius bend can also be used to reduce (disperse) the erosion force.

　　4. Different scope of application

　　In a good construction business environment, pipe elbow and carbon steel pipe bend can be used. If we only consider product cost, then we choose cold pipe bend. After all, the quality of pipe bend is better, but the cost is high. In the construction development process, due to the convenience of engineering construction technology, pipe elbows are more suitable for use in relatively narrow places. The specific construction work environment of the problem needs to be fully considered. Although they can also be used in tight environments. However, some troubles are often encountered in actual use.

　　Actually, from a production parts perspective. The elbow is relatively short. During the actual construction process, if the direction needs to be changed, you can choose which pipe fitting to use according to the specific construction conditions.

　　During the construction process, you can also make reasonable choices based on the analysis of the actual development of the company. Pipe fitting bend and pipe fitting elbows are two different pipe components, so the construction can be completed better and the construction quality can be improved.
