Protecto 401 Lined Pipe and Fittings
U.S. Pipe’s PROTECTO 401 Lined Ductile Iron Pipe and Fittings provide excellent protection
and the strength necessary to do the job in tough sewer pipe applications. PROTECTO
401 has been successfully used in thousands of sanitary sewer applications and has
been proven with both laboratory testing and two decades of actual sewer service on
all sizes of Ductile Iron pipe and fittings.
PROTECTO 401 Ceramic Epoxy Lining was designed specifically for protection of Ductile
Iron for sanitary sewer service by providing a reliability similar to cement mortar lining in
drinking water service but having the excellent chemical resistance of a novalac epoxy for
septic sewer service. Easily recognized brownish red bells and spigots, as well as
stenciling showing “for sewer only”, ensure that the correct lined pipe is used for sewer
service. This concentration of design and formulation effort has resulted in a Ductile Iron
pipe lining system with excellent durability, resistance to undercutting, and resistance to
chemical attack
