Frequently Asked Questions

What is a Carbon Steel Sweepolet?

A Carbon Steel Sweepolet is a contoured branch outlet fitting used to connect a branch pipe smoothly to a main pipeline.

What is a Sweepolet used for?

A Sweepolet is used to create reinforced branch connections while providing a smooth transition between the main pipe and branch pipe.

What is the difference between a Sweepolet and a Weldolet?

A Weldolet has a compact profile and suits most standard process piping. A Sweepolet has a long, swept radius that reduces stress concentration and supports smoother flow, making it better for pipelines, cyclic or vibrating service, and piggable lines.

Can Carbon Steel Sweepolets be used for high-pressure piping?

Yes. Carbon Steel Sweepolets can be used in high-pressure piping when the correct material grade, pressure rating, size, and applicable design requirements are selected.

What is ASTM A105 Sweepolet?

An ASTM A105 Sweepolet is a forged carbon steel branch outlet fitting manufactured from ASTM A105 material for pressure piping applications.

Can Sweepolets be used for branch connections?

Yes. Sweepolets are specifically designed to provide secure branch connections between a main pipe and a smaller branch pipe.
