Alkali Line Spool
An Alkali Line Spool is a component of piping designed for the safe transfer and distribution of alkaline or caustic chemicals within industrial piping systems. It is manufactured using the corrosion-resistant materials such as PPH, FRP, PVDF, HDPE, Stainless Steel, or lined piping to withstand highly alkaline environments.
Alkali line spools are used to connect tanks, pumps, valves, and processing equipment to ensure the leak-proof performance, chemical resistance, and long operational life, and long service life in industries such as chemical processing, water treatment, pharmaceuticals, and manufacturing.
