Skills requirement:

1 1/4 Inch Asme B16.9 90 Long Radius Elbow requires control of the radius of curvature. For example, if the radius is 1.5D, the radius of curvature must be within the required tolerance. Since most of these pipe fittings are used for welding, in order to improve the quality of the welding, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, how thick the edges are, what the angle is and the range of deviation. There are provisions, the geometry is much more than the pipe fittings. The surface quality and mechanical properties of the elbow are basically the same as the tube. For the convenience of welding, the material of the steel of the pipe to be connected is the same.
