This 45 degree elbow can change the flow direction of 45 degrees. As a pipe connection, it is used between two pipes at right angles.
In the field of butt welded steel elbows, it looks like half of a 90 degree elbow. Typically, a 90 degree elbow can be a seamless elbow or a welded elbow. The ends of the tube are bent at a 45 degree angle, which is a 45 degree seamless elbow.
The 45 degree elbow is usually made as an LR (long radius) elbow. There are only a few occasions, for example, very tight places where people use short-radius elbows.

We determine the diameter of the tube blank according to the law of the volume change of the metal material before and after plastic deformation. The diameter of the tube blank used is smaller than the diameter of the elbow. Then we control the deformation process of the blank by the core mold, so that the compressed metal in the inner arc flows, compensating for other parts thinned by the expansion of the diameter, thereby obtaining an elbow with uniform wall thickness.
1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends of the 45 degree elbows are all turned into bevels, leaving a certain angle with a certain edge.
2. The surface quality and mechanical properties of the elbow are basically the same as the tube. In order to facilitate the welding of the elbow, the pipe is the same as the steel of the pipe to be connected.
3. The steel we use to make elbows is used as engineering and building structural parts. In alloy steel, the total amount of such steel alloys is low, but the production and use amount is large.
