Dosing Line Spool
Dosing Line Spool is a section or division designed to accurately transport and inject the quantities of chemicals, additives, or treatment fluids into an industrial process system. It is commonly used in industrial fluid handling, chemical processing, water treatment, and pharmaceutical applications to ensure the precise dosing, safe flow control, and efficient distribution of chemicals.
Dosing Line Spool assemblies are manufactured using materials such as PPH, FRP, HDPE, PVDF, or stainless steel (SS), depending on the chemical compatibility and operating conditions. They can include flanges, valves, connectors, injection points, and support fittings for easy installation and reliable operation.
