The stainless steel 45° short elbow is used to change the direction of the pipe, and the bent part has a gradual curvature. Its two ends need to be welded on the pipe to adapt to the change of the 45° angle of the pipe.
The manufacturing process of seamless elbows：
1）Heat Bending: Hot mandrel bending is performed using straight steel pipes. After heating the steel pipe at a high temperature, the pipe is gradually pushed, expanded, and bent by the tool inside the mandrel.
Hot mandrel bending can be used to manufacture seamless elbows with a wide range of sizes. The characteristics of mandrel bending depend largely on the overall shape and size of the mandrel.
Smaller thickness deviations and larger bending radii. At the same time, the number of required welds can be greatly reduced, improving the quality and availability of the pipe.
2）Cold Bending: Cold bending is the process of bending straight steel pipes at room temperature in a bending machine. Cold bending is suitable for pipes with an outer diameter of 17.0 to 219.1 mm and a wall thickness of 2.0 to 28.0 mm.
Cold bending can produce small-radius elbows, which is a fast and inexpensive bending method.
Short radius elbow center-to-end distance is equal to an inch NPS (R=1.0D), it is usually used in narrow areas.
