Buttweld Carbon Steel and Stainless Steel Pipe Fittings
All fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the bw fitting.
What does Short Radius (SR) or Long Radius (LR) means?
You will often hear SR45 elbow or LR45 elbow. The 45 or 90 refers to the angle of the bend for butt weld fitting to change the direction of flow. A long radius elbow (LR 90 Elbow or LR 45 elbow) will have a pipe bend that will be 1.5 times the size of the pipe. So, a 6 inch LR 90 has bending radius that is 1.5 x nominal pipe size. A short radius elbow (SR45 or SR90) has pipe bend that is equal to the size of fitting so a 6” SR 45 has bending radius that is 6” nominal pipe size.
What is a 3R or 3D elbow pipe fitting?
First, the term 3R or 3D are used synonymously. A 3R butt weld elbow has bending radius that is 3 times the nominal pipe size. A 3R elbow is smoother than SR or LR fitting.
A concentric reducer buttweld fitting is symmetrical: both ends are aligned along the center.
An eccentric reducer butt weld fitting is not symmetrical: ends are off center of one another.
