Product Description

The API Control Rod (SKU 801UC0, MPN SCRU0300) is a control rod for flanged expansion joints, designed for 3-inch pipe size with a 14-inch overall length. It is compatible with double-bulb expansion joints and restricts motion in the expansion direction, supporting double-bulb or single-bulb joint types.

Frequently Asked Questions

What is an API control rod for flanged expansion joints used for?

An API control rod for flanged expansion joints restricts axial movement in the expansion direction, protecting piping systems from over-extension. It is used in industrial applications such as HVAC, steam, and process piping where double-bulb or single-bulb expansion joints are installed.

What are the specifications of the API SCRU0300 control rod?

The API SCRU0300 control rod has a 3-inch pipe size and a 14-inch overall length. It is compatible with double-bulb expansion joints and restricts motion in the expansion direction. The part number is SCRU0300, and it supports double-bulb or single-bulb joint types.

Where to buy API control rods for expansion joints worldwide?
