CHANGE OF DIRECTION

Socket Weld Elbows

Socket weld elbows change the direction of a pipe run. The elbow angle establishes the turn; the socket connections receive the adjoining pipe ends.

01 / PRODUCT OVERVIEW

A controlled change in direction.

An elbow connects two pipe sections on different axes. A 45° configuration makes a shallower turn; a 90° configuration creates a right-angle change in the route.

In a socket-weld connection, the pipe enters a recessed end in the fitting and is joined by an external weld. The compact body and clearly defined connection faces give this fitting its characteristic form.

02 / CONFIGURATIONS

How the configurations differ.

45° elbows

A shallower change of direction for a pipe route that does not require a right-angle turn.

90° elbows

A right-angle change in direction. Orientation and available clearance belong in the layout review.

03 / PRODUCT KNOWLEDGE

Understand the turn in the pipe route.

Direction and connection size describe different things.

The elbow angle describes the change in direction between the adjoining pipe sections. The socket size describes the connection at each end. Keeping those two ideas separate makes the fitting’s role easier to understand.

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

A 45° elbow makes a shallower turn; a 90° elbow creates a right-angle change in the pipe route. The piping layout determines the angle and orientation.

Does the elbow angle identify its connection size?

No. The angle describes the turn in the route; the socket size describes the pipe connection at each end. They are separate parts of the fitting description.

04 / SELECTION CONSIDERATIONS

What matters in the application.

Layout & clearance

Check the required change in direction against the pipe layout, available space and any drawing-controlled dimensions.

Connection compatibility

Identify the mating pipe and required connection sizes. A fitting name alone does not establish compatibility.

Material & duty

Select the material and governing specification for the service conditions established by the project.

05 / UNDERSTAND THE SPECIFICATION
