On the surface, there is only one word difference between seamless elbow and seamless elbow pipe. In fact, they are very different. One is an elbow, and the other is a bent pipe. The following is an analysis of the differences between the two.
1. Technology
The processes of seamless elbows include hot pressing, hot pressing and cold pressing; the processes of seamless pipe bends include hot pressing, medium frequency bending and CNC bending. Seamless elbows are commonly made with medium frequency bending.
2. Erosion intensity
The R of seamless elbow and seamless elbow is different. R represents the position that controls the length of seamless elbow and seamless elbow. The erosion intensity of small R through the medium is much greater than that of large R. For example, the erosion intensity of 1D seamless elbow is not as good as that of 1.5D seamless elbow. The erosion intensity of 1.5D seamless elbow is lower than that of seamless elbow. The erosion intensity of seamless elbow is lower than that of seamless elbow. Seam elbow erosion wear is greater.
3. Application
Applications such as bridges require long-span seamless elbows, and seamless elbows are not suitable.
Therefore, we can see that seamless elbows and seamless elbows have their own advantages in various industries.
