A grooved elbow refers to a pipe fitting with grooves at its ends, designed for connecting two pipes at various angles. The grooved end of the elbow features a series of small dents or grooves, allowing easy and secure connection to the pipe using mechanical couplings or clamps.

Grooved elbows are commonly used in industrial and commercial applications where high flow rates, pressures, or temperatures are required in the pipeline system. Grooved elbows are preferred over other types of elbows because they are easy to install, requiring no welding or threading, and can be easily disassembled and reassembled for maintenance or modifications. The grooved elbows come in various sizes and configurations to accommodate different pipeline systems and applications.
