Drain Spool
A Drain Spool is a fabricated piping component that is used in industrial piping systems to safely collect, discharge, or drain liquids, chemicals, condensate, and process chemicals from pipelines, tanks, vessels, and equipment. It is designed to provide control of drainage during the system of operation, maintenance, cleaning, and shutdown processes.
Drain spools are commonly manufactured from materials such as PP, FRP, HDPE, PVC, PVDF, stainless steel, or mild steel. They are depending on the application of chemical compatibility requirements. Drain spools can be customized with flanges, valves, reducers, bends, and threaded connections for easy integration into the piping process systems. These spools are widely used in chemical plants, water treatment systems, pharmaceutical industries, refineries, and the process of chemical industries, where they are safe and efficient fluid drainage.
