BUTT WELDED PIPE ELBOW
Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.
For industrial pipe elbow, the connectin end type is butt weld, according to ANSI B16.25. Butt welded can described butt welding, buttweld, bevel end. BW
ELBOW TYPE
Elbow could be ranged from direction angle, connection types, length and radius, material types.
Classified by Direction Angle
As we know, according to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.
For 90 degree elbow, also described 90d elbow, or 90 deg elbow.
What is Elbow Radius
The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines.
If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.
If radius more than 1.5D, always named bend. elbow bend pipe fittings. Such as 2d elbow, 2d bend, 3d elbow, 3d bend, etc.
Classification by Material
Carbon steel, also called mild steel or black steel. Such as ASTM A234 WPB

Shape Type
Can be equal elbow or Reducing elbow
ELBOW SURFACE
Sand Blast
