Butt Weld Elbow

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

Butt weld elbow is commonly used fitting in piping systems. It has a curved shape and can bend the pipe in a horizontal or vertical direction. It is connected to the pipe through welding, allowing the fluid or gas to flow along a specific path. It can be used to avoid obstacles, pass through walls or floors, and adapt to different spatial limitations and engineering requirements, achieving flexibility in pipe layout and optimizing the design of the piping system.

45° butt weld elbow
90° butt weld elbow
180° butt weld elbow

There are 45° short radius elbows and 45° 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.
It is commonly used in horizontally laid piping systems to change the direction of fluid flow.
It is connected to the pipe by welding, and has high strength and sealing performance, and can withstand high pressure and temperature.
Made of 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.

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.

Functions

Butt weld elbows can change the flow direction of fluid in a piping system. It can redirect the flow of fluid from one direction to another, allowing for adjustments in the flow direction within the piping system.
