A Buttweld Elbow is a high-performance pipe fitting designed to change the direction of a pipeline,featuring beveled ends for direct butt welding to connecting pipes.It is widely used in medium to large‑diameter,high‑pressure,high‑temperature,and critical industrial piping systems.
Key Features
Butt-weld connection:Full circumferential welding ensures strong,rigid,and leak‑proof joints
Seamless or welded construction:Available in seamless(for high pressure)and welded(for general service)
Smooth flow path:Uniform inner diameter reduces turbulence and pressure loss
High structural integrity:Suitable for continuous operation under pressure,temperature,and vibration
Long service life:Minimal risk of loosening or failure compared to threaded fittings
Common Types
Angle:90°,45°,180°
Radius:Long Radius(LR,R=1.5D),Short Radius(SR,R=1.0D)
End type:Beveled end for butt welding
Materials
Carbon steel(ASTM A234 WPB),alloy steel,stainless steel(304,316,316L),duplex steel,etc.
Standards
ASME B16.9,ASME B16.28,MSS SP-43,EN 10253,DIN 2605
Applications
Oil&gas pipelines,refineries,petrochemical plants,power stations,chemical processing,shipbuilding,water supply,heating,and long‑distance transmission pipelines.
