45 Degree, 90 Degree,180 Degree Stainless Steel Elbow
The function of an elbow is to change direction or flow in a piping system. By default, there are 5 opportunities, the 45掳, 90掳 and 180掳 elbows, all three in the long radius version, and in addition the 90掳 and 180掳 elbows both in the short radius version.
Long and Short Radius
Elbows are split into two groups which define the distance over which they change direction; the centre line of one end to the opposite face. This is known as the centre to face distance and is equivalent to the radius through which the elbow is bent.
The centre-to-face distance for a long radius elbow abbreviated LR always is 1.1/2 x Nominal Pipe Size (NPS) (1.1/2D), while the centre-to-face distance for a short radius elbow, abbreviated SR even is to nominal pipe size.
Here below, for example, you will find the
centre to face distance of NPS 2 elbows
(the A distance on the image)
1. 90掳-LR.. = 1.1/2 x 2(NPS) x 25.4 A=76.2 mm
2. 180掳-LR.. = 2 times the 90掳 LR elbow A=152.4 mm
3. 90掳-SR.. = 2(NPS) x 25.4 A=50.8 mm
4. 180掳-SR.. = 2 times the 90掳 SR elbow A=101.6 mm
3D elbows as an example, are calculated with..
3(D) x 2(NPS) x 25.4
45掳 Elbow
The function of a 45掳 elbow is the same as a 90掳 elbow, but the measurement of dimensions is different to that of the 90掳 elbow.

The radius of a 45掳 elbow is the same as the radius of the 90掳 LR (1.1/2D). However, the centre-to-face dimension is not equivalent to the radius as in 90掳 LR elbows. This is measured from each face to the point of intersection of the centre lines perpendicular to each other, distances B on the image. This is due to the smaller degree of bend. Short radius 45掳 elbows are not available.
Standards
The most applied version is the 90掳 long radius and the 45掳 elbow, while the 90掳 short radius elbow is applied if there is too little space. The function of a 180掳 elbow is to change the direction of flow through 180掳. Both, the LR and the SR types have a centre-to-centre dimension double the matching 90掳 elbows. These fittings will generally be used in Furness or other heating or cooling units.
Dimensions, dimensional tolerances and more images, can be found in the main Menu Fittings.
In addition to the defined elbows, there is the Reducing Elbow, which is an elbow with various diameters on the ends. Because this elbow, for many suppliers it is not a standard item, and thus probably a high price with a long delivery time, the use of a normal elbow with a separate reducer is an option if the situation allows.
In other degrees elbows can be machined from a standard elbow. Longer radius type, the centre to face dimension e.g. is three times the nominal size (3D), even is available.
Dimensions, dimensional tolerances etc. for long and short radius elbows are defined in ASME B16.9.
Wall Thickness of Elbows
The weakest point on an elbow is the inside radius. ASME B16.9 only standardizes the centre-to-face dimensions and some squareness dimensional tolerances. The wall thickness at the weld line location even is standardized, but not through the rest of an elbow. The standard states that the minimum tolerance will be within 12.5% of the minimum ordered wall thickness of the pipe. A maximum tolerance is specified only at the ends of the fitting.
Many providers of buttweld elbows (and tees) provide one schedule greater thickness so that sufficient wall thickness, after forming, remains.
