Stainless butt weld pipe fittings conform to ASTM A403, ASTM A960, MSS SP-43 Stainless butt weld pipe fitting dimensions conform to ASTM B16.9 (except Wall) and MSS SP-43 Manufacturing facility is ISO 9001:2008 Material certifications are available upon request.

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. This is due to the smaller degree of bend. Short radius 45° elbows are not available.

6 in. 90 Degree Elbow - Long Radius (LR) - Schedule 10 304/304L Stainless Steel Butt Weld Pipe Fittings

LR 45 Elbow: Long radius 45 degree elbow changes the direction by 45 degrees. SR90 Elbow: Short Radius 90 degree elbow is the same as LR90, except for the measurement between end of elbow to the center line is 1 x NPS.

LR 90 Elbow: Fittings that change direction in a piping system are called elbows. The directional change is given in degrees, such as 45 or 90. Long radius 90 degree elbow has the center line of elbow at 1.5 x NPS from elbow end. 3R elbow has center line at 3 x NPS from elbow end.
