SCH40 GI steel pipe with grooved ends refers to a steel pipe that is manufactured to meet the SCH40 standard for wall thickness and is made of galvanized steel. The "GI" stands for "galvanized iron" indicating that the pipe has been coated with a layer of zinc to protect it from corrosion.
The term "grooved ends" indicates that the pipe ends are designed with grooves to facilitate the installation of mechanical couplings or fittings. Grooved ends are commonly used in fire protection systems, HVAC systems, and other applications where quick and secure connections are required.
