Do you know how that's bent?

Feb 01, 2021

Two common terms used within our industry regarding elbows are center to face and radius or CLR (center line radius).  Some people use theses terms interchangeably.  However, there are very important differences between the two.

 

In the tube fittings industry a short elbow typically refers to an elbow without tangents. A 2" OD short elbow would be bent on a 3" radius and since it does not have tangents the center to face dimension would also measure 3".  On the other hand, a short radius elbow refers to an elbow bent on a radius equal to its diameter. For example a 2" OD short radius elbow would be bent on a 2" radius. This elbow may or may not have tangents. Therefore the center to face dimension could be 2" or it could be longer if it had tangents. A long radius elbow, which is considered standard, is bent on a radius 1.5 times its diameter. For example, a 2" OD long radius elbow is bent on a 3" radius. Once again, the center to face dimension could be 3" (without tangents) or longer (with tangents).

 

Knowing the difference between these different terms can save you some headaches purchasing the correct parts. If you would like to know more, please feel free to contact any of our sales people here at Andron. We look forward to hearing from you.

The difference between 304 and 316 stainless steel are the chemical properties. The key difference is that 316 has the addition of 2-3% molybdenum to the stainless steel. The addition of Molybdenum helps some applications due to the increased corrosion resistance, particularly to chlorides.
