Lined Three Way is a special fitting based on the traditional three-way pipe fitting, with a layer of fluoroplastic (such as PTFE, FEP, PFA, etc.) lining on the inner surface. This product is mainly used for flow division or confluence in corrosive medium pipeline systems, effectively changing fluid flow direction or achieving fluid mixing. Lined Three Way has excellent corrosion resistance, capable of effectively resisting the erosion of corrosive media such as strong acids, strong alkalis, and organic solvents, while maintaining the advantages of three-way fittings such as reliable connection and good flow performance. Lined Three Way fittings are widely used in corrosive medium pipeline systems in industries such as chemical, petrochemical, pharmaceutical, pesticide, and dye.
