Confirm the angle and radius
State the angle and centre-line radius with units. If using an R:D ratio, define D and give the required radius on the drawing.

Pipe Elbows & Bends
Pipe elbows and bends change the direction of a piping run. The angle, centre-line radius, end sizes and wall requirements define the geometry; standard elbows and other bends must be specified clearly.
PRODUCT DETAILS
Specify the connection completely.
We can also make custom sizes, wall thicknesses and other dimensions to your drawing. Send the pipe-end requirements and your drawing with your RFQ so we can confirm the details.
| Parameter | Details to confirm |
|---|---|
| Type | Elbow or bend; standard or drawing-based geometry |
| Geometry | Angle and centre-line radius with units; define D when specifying an R:D ratio |
| Ends | Outside diameter, wall thickness, end preparation and straight tangent length at each end |
| Reference | ASME B16.9 / B16.28 where applicable, or the project drawing |
Product dimensions, material grades and documentation are confirmed against your enquiry and applicable project requirements.
Primary dimensional reference: ASME B16.9 (overall scope NPS 1/2–48) for covered elbows; project drawing for other bends. Confirm the product type, edition and applicable size before order.

SELECTION & ENQUIRY
The details that make the difference.
Define both ends
Specify the outside diameter, wall thickness and welding-end preparation at both ends. Give each straight tangent length separately where required.
Send special geometry
For non-standard bends, provide the drawing number and revision, orientation, critical dimensions and tolerances, plus inspection requirements.

Product overview
Two ways to change the direction of a pipe run.
Pipe elbows are fittings used for a directional change and are commonly specified by nominal size, schedule, radius, material and fitting standard. Pipe bends are formed sections of pipe, often made to a project-specific radius, angle and tangent length.
Before quotation, provide the available drawing, pipe size, wall thickness, material, standard, angle, radius, quantity, destination and any documentation requirements.

COMMON QUESTIONS
Before you send the enquiry.
What should I specify for a non-standard bend?
Include angle, centre-line radius, pipe outside diameter, wall requirements and any straight tangents. A drawing helps define the complete geometry.
Which angle and radius details should I state?
State the bend angle and required centreline radius, together with pipe diameter and wall thickness. Attach a drawing where orientation or end-to-end dimensions matter.
Can two elbows of the same nominal size have different dimensions?
Yes. Angle, radius and governing dimensional requirements can differ. Check the required centre-to-end dimensions rather than selecting by nominal size alone.
How should multiple pipe bends be identified in one order?
Give each bend a unique item number and drawing revision. List its angle, radius, tangent lengths, pipe dimensions and material on the same line so that similar bends are not confused.
Should I specify end preparation?
Yes. Identify the required connection and welding-end preparation from the approved project documents. A catalogue image does not define the supplied end geometry.
