OEM Stainless Steel Weld Pipe Factories – Black Steel Pipe Elbow – C. Z. IT

PRODUCT PARAMETERS

STEEL 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.

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.

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.

Classification by Material

According to the valve body material, it has stainless steel, carbon steel and alloy steel elbow.
