TYTPETYPES OF BUTT WELD FITTINGS

TEES

Tees are butt weld fittings used to combine or divide process flow, and Reducing Tees additionally allow for butt weld fittings size change.  The run outlets of the tee are the two in-line outlets, and the branch is the third outlet.  The branch outlet is the reducing outlet in a Reducing Tee.

ELBOWS

An elbow is a butt weld fitting is used to change the direction of flow in a piping system, usually at the 90° or 45° angle. Like a reducing tee, reducing elbows also exist to simultaneously change flow direction and reduce flow diameter.  90 degree elbows are also available in both short radius and long radius patterns, whereas 45 degree elbows are only available as long radius.  

LONG RADIUS (LR) VS SHORT RADIUS (SR) ELBOWS

A long radius butt weld elbow has a radius of curvature (Identified as [A" in the above drawing) is 1.5 times the nominal diameter, and a short radius butt weld elbow has a curvature that is 1.0 times the nominal diameter of the butt weld fitting. Long radius butt weld elbows give less frictional resistance to the fluid than the short radius butt weld elbows.  Short radius butt weld elbows are generally cheaper and can be used where space is a concern, but they also create a greater pressure drop than long radius butt weld elbows.

Bend vs Elbow

There is often confusion around bends and elbows.  Bends are generally made or fabricated as per the need of the piping design, whereas elbows are manufactured in mass quantities, conform to industry standard size specifications, and available off the shelf. Butt Weld Fitting bending techniques also face constraints regarding material thinning, and if not done properly, there can be concerns regarding the pressure integrity of the line being maintained.  Elbows are most commonly used for SR and LR bends, but when the curvature exceeds 3R, bends are most commonly utilized. 

Reducers

Reducers are butt weld fittings used to facilitate a reduce the flow diameter in a piping system.  Concentric reducers are most commonly used, as they create less friction for the fluid flow, however, eccentric reducers are utilized when space  or alignment is a concern. 

Cross

Crosses are a 4 way butt weld fitting, with 1 inlet and 3 outlets or vice versa.  These are sometimes referred to as 4-way tees.

Caps

Caps are butt weld fittings used to terminate the flow, welding to the end of a butt weld fitting or pipe.
