Start with the layout
Identify the line or drawing where the right-angle change occurs.
A right-angle turn.
Every detail defined.
A 90° elbow turns the pipe route through a right angle. Bring the angle, radius and connection details together in one clear enquiry.
90° / DIRECTION CHANGE
The same angle does not mean the same footprint.
The radius and centre-to-end dimensions affect the space occupied by an elbow. Use the approved layout to identify the geometry, rather than substituting one radius for another.
Keep LR and SR distinct
Long-radius and short-radius configurations should not be treated as dimensionally interchangeable.
Specify the connection
Include end size, wall thickness and the applicable weld-end requirements.
Flag any special geometry
Separate drawing-specific dimensions from the standard configuration.
ENQUIRY CHECKLIST
Specify the complete fitting.
These fields describe the requirement. Numerical dimensions must come from the specified standard or approved drawing.
| Requirement | Include in your enquiry |
|---|---|
| Direction change | 90°. |
| Radius configuration | Required designation and applicable reference dimensions. |
| Centre-to-end | Specified standard values or approved drawing requirements. |
| End sizes | Nominal connection sizes and wall thicknesses. |
| Material | Complete fitting specification and grade. |
| Documentation | Drawing revision, inspection and certificate requirements. |
NEXT STEPS
Connect geometry with the specification.
Availability and suitability require review of the exact configuration.
Material families
Find the family, then record the full product specification and grade.

Explore guide →COMMON QUESTIONS
Before you specify 90° elbows
Can I replace a long-radius elbow with a short-radius elbow?
Not without project review. The geometry and its effect on the system need to be assessed by the responsible engineer.
Does a 90° angle define centre-to-end dimensions?
Not by itself. The radius, size and applicable standard also matter.
Should I state a schedule or a wall thickness?
Use the approved specification. Include the governing dimensional reference when using a schedule designation, and identify any special thickness.
Do the illustrations provide dimensions?
No. The illustrations explain geometry only and are not manufacturing drawings.
