Frequently asked questions
What is the difference between a long radius and short radius elbow?
A long radius (LR) elbow has a centre-line radius of 1.5 × NPS and is the default choice. A short radius (SR) elbow has a radius of 1.0 × NPS. SR elbows save space but add pressure drop and are not suitable for pigging.
What is the centre-to-end dimension of a 90° LR elbow?
For ASME B16.9 90° LR elbows the centre-to-end dimension A is 1.5 × NPS in inches. For example, a 6" elbow is 229 mm (9 in) and a 4" elbow is 152 mm (6 in).
What is the difference between a concentric and an eccentric reducer?
A concentric reducer keeps both ends on the same centre line. An eccentric reducer has one flat side. Eccentric reducers go on pump suctions with the flat side on top, so air pockets cannot form.
What is a 3D or 5D bend?
A bend whose centre-line radius is 3 or 5 times the nominal pipe size. They are usually made by induction bending and supplied with tangent lengths. 5D bends allow pigging in pipelines.
