Why is it so important to test linings for Ductile Iron pipes on Ductile Iron samples instead of steel or concrete?

Ductile Iron Pipes have a unique oxide layer resulting from the manufacturing processes. Protecto 401™ is designed to work in conjunction with this oxide layer.  Other substrates, such as steel or concrete, do not have the cast-in oxide layer that is integral to ductile iron.

Over decades of research, no efficient blasting method has been devised to completely remove the oxide layer in ductile iron.  Since the substrates are totally different, testing on steel or concrete for Ductile Iron linings is not reliable.

Beware of manufacturer's who claim to make one product for use on Steel, Ductile Iron and Concrete.

Testing and "real world" experience matter.  Make the responsible choice- use Protecto 401™ Ceramic Epoxy- tested in Ductile Iron Pipe and Fittings for three decades.

Nothing protects tough sewer pipe applications more effectively than ductile iron pipe and fittings lined with Induron's Protecto 401TM Ceramic Epoxy. It's been successfully used in hundreds of sanitary sewer applications and proven both in laboratory testing and decades of actual sewer service.

Since 1981, literally thousands of miles of ductile iron sewer pipe have been lined with Protecto 401TM. Give your projects and your reputation the protection they deserve. Specify ductile iron pipe and fittings lined with Protecto 401TM.

Ceramapure may be used AS EQUAL for Protecto 401 in sewer service

Protecto 401 is not for use as a Potable Water Lining.
Use Induron's Ceramapure PL 90 for Potable Water Lining of Ductile Iron Pipe.
