### What is the difference between long radius and short radius bend in oil and gas pipes?

The difference between the 2 is length and curvature. A short radius elbow offers a tighter turn than the long radius. The short radius elbow is cheaper and will fit into a tighter space.

Short

### What is the difference between long turn and long radius in piping design?

Same thing consider the following Long turn ell ( Sweep) regular sweep and short sweep = 1/4 bend all are 90 degree fittings

### What is the basis of using long radius and short radius elbow?

It depends where the pipe is heading, flow is better in along radius, but sometimes there is no room for it.

### What is the formula of 90 degrees elbow?

If radius is short it is 1 times pipe diameter. If it is a long radius it is 1.5 times nominal pipe diameter.

### How do you calculate the center of a 90 degree pipe elbow?

If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius

### What is the difference between long radius and short radius elbow?

In the area of industrial pipe fittings: Long radius 90 deg elbow has a take off dimension of one and one half times the nominal diameter of the pipe. Ex-4 inch pipe has an actual diameter of 4.5, for the elbow the take off dimension would be 4"*1.5=6". The short radius elbow take off dimension is the same as the nominal size, 4". To add to the point, a short radius elbow can be used typically where space is a constraint. Hence fluid flow is also restricted in this case unlike in case using of Long Elbow.

### What is the difference between a 3d bend and a 3R ell?

There is no difference. Different suppliers and contractor describe the same situation with 3R or 3D. Here is how to think about it. A piping segment is formed or bent at a radius. The radius is measured at the centerline of the bend. The radius of the bend centerline is 3 times the nominal diameter of the piping segment being bent. 3R means the bend radii is three times the nominal pipe diameter. 3D means three times the nominal pipe diameter is the bend radii of the piping segment. Caution don't begin to convert 3R to 1.5D. Not applicable with this terminology. Standard long ells can be purchased with 3R bends, being 10 inch pipe ells have a bend radii of 30 inches.

### Does grind have a long i or short i sound?

The I has a long I sound, as in gripe and find.

### Why does Vesta only have one number for its radius?

Vesta is round and its radius is only one number unlike other asteroids which have more of an oblong shape -like a potato- and so their radius is expressed for the long side and the short side.

### Is short radius bend is suitable for steam pipeline?

Sure it is. You need to know, however, where to use it. for long runs of pipe with bends, it would be preferable to use long radius ells, to prevent excessive flexing of the fitting as the pipe expands and contracts due to thermal expansion. However, in short runs (less than 50 feet (or 15 meters)) of straight pipe without expansion joints and less than 300 degrees F (170 C) differential temperature, (steam temp. minus ambient temp.) short radius bends (or elbows) are more than adequate. As the diff. temp. increases the straight runs of pipe should be decreased in length, or expansion joints installed, to prevent excessive flexing at the joints and fittings.

### For pipefitters what is the take off on a 6 inch short radius 90 degree ell?

Short Radius 90 degree elbows are the same as pipe size.... Long Radius 90's are pipe size times 1.5.... so a 6" (SR) elbow is 6"... a 6" (LR) elbow would be 9"
