Elbow

LR & SR Pipe Elbows | 45°/90°/180° | Seamless & Welded Industrial Fittings

Pipe elbow is standard pipe fitting to adjust pipeline flow direction, supplied in long radius and short radius, 45°,90°,180° angles. We produce carbon steel elbow for heavy industrial piping and stainless steel elbow for corrosive medium. Seamless and butt weld elbow meet ASME B16.9 standards for high pressure & temperature projects.

As professional pipe elbow manufacturer, we support custom size, wall thickness and connection types including threaded & socket weld.

Elbow

Main Classification

By radius：Long Radius Elbow (1.5D), Short Radius Elbow (1D)

By angle：45°,90°,180° return bend

By craft：Seamless elbow, welded elbow

By connection：Butt weld elbow, threaded elbow, socket weld elbow

Application Limits

Short radius elbows for limited space; long radius for low turbulence long-distance pipelines. Not for ultra-small bore explosion-proof piping (choose threaded elbow separately).

Comparison Table：Long Radius VS Short Radius Elbow

Item	Long Radius Elbow	Short Radius Elbow
Radius	1.5D	1D
Flow loss	Low, smooth flow	Higher flow resistance
Installation space	Require larger space	Compact narrow layout
Pressure adaptability	All pressure classes	Low & medium pressure only
Common usage	Long-distance main pipelines	Indoor compact branch pipes

Comparison Table：45° / 90° / 180° Elbow

Item	45° Elbow	90° Elbow	180° Return Bend
Flow deflection angle	45 degrees	90 degrees	180 degrees, reverse flow
Flow resistance	Minimal	Medium	Highest resistance
Typical layout purpose	Gentle pipeline turn, long distance main pipe	Vertical/horizontal right-angle steering	U-shaped loop, heat exchange circulation
Common usage scenario	Long oil/gas trunk lines	Factory general process piping	Boiler, cooling circulation system
Pressure recommendation	All pressure grades	Full range pressure	Low & medium pressure circulation lines

FAQs

What’s the difference between long radius and short radius elbows?

Long radius (1.5D) has low flow resistance for main pipelines; short radius (1D) saves space for compact branch piping.

Which elbow angle is most widely used?

90° elbow is standard for vertical and horizontal pipe turns; 45° for gentle long-distance routing, 180° for circulating loops.

What connection types can elbows be made with?

Butt weld, threaded and socket weld ends to match different piping systems.

What specifications can you customize?

Custom angles, wall thickness, sizes DN15–DN3000 and special schedules are supported.

Are seamless elbows suitable for high-pressure pipelines?

Yes, seamless elbows feature uniform wall thickness and perform well under high pressure.
