Frequently Asked Questions

A Carbon Steel Elbolet is a forged branch outlet fitting used to make a branch connection on a pipe elbow or curved piping section.

An Elbolet is designed for branch connections on elbows, while a Latrolet is used for lateral branch connections, typically at an angled position on the main pipe.

Elbolets are commonly manufactured according to ASME B16.11 and MSS SP-97 requirements.

Yes. Carbon Steel Elbolets are available in high-pressure classes such as Class 3000, 6000, and 9000, depending on the design and application.

An ASTM A105 Elbolet is a forged carbon steel branch outlet manufactured from ASTM A105 material, commonly used for industrial pressure piping systems.

Yes. Elbolets are specifically designed to provide branch connections on pipe elbows, making them suitable where a branch outlet is required on a curved section.

Yes. A long-radius (1.5D) and short-radius (1.0D) elbow have different curvatures, so the Elbolet must match the elbow radius to ensure a proper weld fit. Always specify the elbow size and radius when ordering.
