A Reducing Elbow is a type of fitting which is used to join two pieces of pipe of different sizes. The reducing elbow is so called because it looks like a reducing piece and elbow combined into one.
When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. It required more space than short radius elbow.
An elbow is a Pipe Fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.
Types of reducing elbow:
The reducing elbows are available in various types like:
90° reducing elbow
45° reducing elbow
135° reducing elbow
180° reducing elbow etc
In long radius elbow, centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe.
Buttweld pipe fittings comprises of long radius elbow, Concentric Reducer, eccentric reducers and Tees.They are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting`s dimensions and tolerances are defined as per ASME standard B16.9.
Butt Weld fittings are also called Welded Pipe fittings. These welded fittings in carbon steel and stainless steel offer many advantages compared to threaded and socketweld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½" to 102".
Reducing Elbow: Fittings that change direction in a piping system are called elbows. The directional change is given in degree such as 45 or 90. Long radius 90 degree elbow has the center line of elbow at 1.5 x NPS from eblow end. And the elbow ends in two different outdiameters
