Domestic Carbon Steel Long Radius 90° Weld Elbow

90° long radius direction change for welded piping systems. Carbon Steel 90° Elbow for water, steam, and general fluid service.

• 90° direction change — standard fitting for changing pipe direction
• Long radius pattern — smooth 90° turn for lower pressure drop
• Carbon Steel construction for reliable long service life
• Butt weld ends — welded directly to matching pipe

Overview

Domestic Carbon Steel Long Radius 90° Weld Elbow is a 90° butt weld elbow for changing pipe direction in welded piping systems. Long radius elbows make a sweeping 90° turn with lower pressure drop than short radius.

Common Uses

• Changing pipe direction in plumbing rough-in
• Water supply distribution and branch connections
• HVAC heating and cooling piping
• Industrial and commercial piping systems
• Connecting to valves, pumps, and equipment

Key Features

• 90° butt weld pattern
• Long radius pattern — smooth 90° turn for lower pressure drop
• Carbon Steel body
• End connections: Butt Weld

Frequently Asked Questions

What is the difference between long radius and short radius elbows?

Long radius elbows have a 1.5D centerline radius for smoother flow and lower pressure drop. Short radius elbows use a 1D radius for tighter spaces where clearance is limited.

What is the difference between a 45 and 90 degree elbow?

A 90-degree elbow makes a sharp right-angle turn. A 45-degree elbow makes a gentler change in direction with lower pressure drop and turbulence — preferred where flow efficiency matters.

What do STD and XH mean?

STD (standard) and XH (extra heavy) are butt weld wall schedules. Match the fitting schedule to the pipe schedule so the weld lands on equal wall thickness.

Are lead-free fittings required for potable water?

Yes. Federal law and most state codes require lead-free (less than 0.25% weighted average lead content) fittings on potable water systems.
