Butt Weld Elbow – Adjusting the Flow Direction Of Fluid In Piping Systems

Butt weld elbow is a commonly used fitting in piping systems. It is used to connect two pipes with the same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degrees or 90 degrees.

Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows are mainly used for elbow with higher pressure and temperature than other connection types (socket welded elbow or threaded pipe elbow)

 

Butt weld Elbow Types

 

180° butt weld elbow

180 Degree steel elbow helps change direction at 180 degrees, since it usually results in low pressure. Its application is limited to minimal deposition and low turbulence system.

• There are 180° short radius elbows and 180° long radius elbows. Long radius elbows provide smaller flow resistance and pressure loss, and are suitable for general piping systems. Short radius elbows are suitable for limited space or situations that require faster changes in flow direction.
• They are commonly used in situations where there is a need for a significant change in direction, causing the fluid to flow in the opposite direction.
• It is connected to the pipe by welding. It has high strength and sealing performance, and can withstand high pressure and temperature.
• Made of materials such as stainless steel, duplex steel, or special alloy steel, it has corrosion resistance and can resist corrosion from oxidizing agents, acids, alkalis, salt solutions, and other corrosive media.

90° butt weld elbow

90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. It is the common degree in all the pipeline systems and used most in all different degree of elbows. (As it is convenient to suit to steel construction and structural.)

Long radius 90 degree elbow

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.

Short radius 90 degree elbow

SR 90 degree elbow is the same as the pipe elbow mentioned above, but the diameter is shorter. Therefore, this kind of steel elbow is often used when space is not.

45 Degree Steel Pipe Elbow

45 degree elbow is second common use after 90 degree elbow.

45 degree elbow of long radius

The pipe elbow is mounted between two pipes so that the fluid direction can be changed to 45 degrees. Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure.

45 degree elbow of short radius

SR Elbow in 45 degree is usually attached to copper, plastic, steel, cast iron and lead, and can also be connected to stainless and rubber fixtures. It is widely used in chemical, food, water supply facilities, electronic industry, chemical pipelines, horticulture, agriculture production, solar equipment pipelines, air conditioning pipeline and other fields.

What is the Elbow Radius?

The elbow radius mean curvature radius. If the radius is the same as the pipe diameter, it is called a short radius elbow, also called an SR elbow, normally for low-pressure and low-speed pipelines.
If the radius is larger than the 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.
