45 Degree Elbow
A pipe elbow is one kind of pipe fittings which can change the liquid or gas flowing direction in a piping system. It is mainly used to connect two pipes,sometimes called a “quarter bend”.
A 45 degree elbow is the elbow which can change the flow direction in a 45 degree . As a joint, it is used between the two pipes which has this right angle.
The function of a 45° elbow is the same as a 90° elbow, but the measurement of dimensions is different to that of the 90° elbow. The radius of a 45° elbow is the same as the radius of the 90° LR (1.1/2D). However, the center to face dimension is not equivalent to the radius as in 90° LR elbows. This is measured from each face to the point of intersection of the center lines perpendicular to each other, distances B on the image.
In the field of butt welding steel elbows, it looks like a half of the 90 degree elbow ,Commonly , the 90 degree elbows can be a seamless elbow or a welded elbow. Bending the two ends of pipe to a angle of 45 degree, it is a 45 degree seamless elbow.
The 45 degree elbows usually are manufactured as LR (Long Radius) elbows . Only in little occasion, for example, very tight place, people use the short radius elbow. because there is nearly no factory produce such 45 degree short radius elbow, engineers or workers would cut a 90 degree elbow into two 45 degree elbow instead.
