1D Bend factory believes that "1D elbow" and "bend pipe" are introduced separately, so let's get to the point, is there any difference between the two?

　　1.1D Bend factory believes that the first is the process: 1D elbows have hot pushing, cold pushing, hot pressing and other processes; the bending process includes intermediate frequency bending, hot pushing and CNC bending. Among them, carbon steel and alloy steel are the most commonly used elbows in pressure pipes, and stainless steel is hot push.

　　2.1D Bend factory according to R radius: The R radius of 1D elbow is a specified value, that is to say, there are certain standards. For example, the R of the 10" long radius elbow is 381mm, and the short radius elbow is 254mm, but the elbow is different.

　　3.1D Bend factory feels the difference in scouring force: the 1D elbow is different from the elbow itself. R is a position that controls the length and size of the elbow or elbow, just like the difference between the size of the circle we adults use our arms to circle and the size of a child's arm circle. In this way, it is easy to understand that the small R must wear more than the large R when passing through the dielectric material.

　　4.1D Bend factory believes that there is also a special case, such as bridges, which must be spanned with long-span elbows. At this time, the elbow is definitely useless, and the general heat pipe uses the elbow.
