PROTECTO 401™Ceramic Epoxy Lining (www.protecto401.com) from Induron® 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.
Tested against salt spray, 20% sulfuric acid, 35% sodium hydroxide immersion and distilled water immersion.
PROTECTO 401 Ceramic Epoxy is also resistant to a wide range of oils, greases, solvents, detergents and fuels.
Intended for use in domestic sanitary sewage lines.
PROTECTO 401™ Lined 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.
FAQ: Can PROTECTO 401™ Ceramic Epoxy be repaired at the jobsite location if the lining is damaged during installation, or if a length of pipe must be cut to meet a field dimension?
Yes. PROTECTO 401™ Joint Compound is the material approved for patching the ends of field cut pipe or for repairing any damage detected prior to installation. A touch-up kit is available for contractors and fabricators.
FAQ: How does PROTECTO 401™ compare to other competitive lining materials with respect to its ability to adhere to the inside surface of ductile iron pipe?
Competitive lining materials do not compare well with PROTECTO 401™’s ability to adhere to the inside surface of ductile iron pipe. PROTECTO 401™’s ability to resist undercutting and disbondment as determined by standardized testing on production run ductile iron pipe far surpasses any ductile iron pipe lining material that has been tested to date.
FAQ: How is PROTECTO 401™ tested after the initial application of the epoxy so as to ensure compliance with the specifications?
Following the application of PROTECTO 401™ to the interior surfaces of ductile iron pipe or fittings at a nominal thickness of 40 mils, a nondestructive pinhole detection test and a thickness test is performed to ensure the material forms a sound, chemically resistant protective lining.
FAQ: How long has PROTECTO 401™ been used in underground domestic sewage service and what does the record show about its performance?
PROTECTO 401™ has a history of domestic sewage service dating back to 1981. During that time period, thousands of miles of PROTECTO 401™ lined ductile iron pipe have been installed all over the United States, South America, and the Middle East with no known lining failure.
FAQ: How resistant is PROTECTO 401™ lining to the abrasive materials commonly found in a fast flowing sewer?
Extremely resistant! Abrasion resistance of coatings is normally measured using ASTM D-4060. However, this test is conducted on coatings applied to flat steel panels, and is not applicable to curved specimens of ductile iron pipe. There is a European standard test for measuring the Abrasion Resistance of Sewerage Piping – EN 598, which was used to test PROTECTO 401™.
In this test (metric units have been converted to approximate English units), a pipe sample approximately 40” long is filled with a siliceous gravel to a depth of approximately 1½” and filled with water to the same level. The gravel particle size is graded to fall between 0.08” and 0.4” with an average particle size of approximately 0.24”. The sample is fixed to a frame which is rocked between plus 22.5° and minus 22.5° every three to five seconds. After rocking through 100,000 cycles, the lining loss is measured as prescribed in the standard. The allowable lining loss shall not be greater than 23.6 mils.
In the testing conducted on a PROTECTO 401™ lined sample of ductile iron pipe, the test was conducted for a duration of 1,000,000 cycles (ten times longer than required). Lining loss was measured at only 2 mils.
FAQ: Is PROTECTO 401™ Amine Cured Novalac Ceramic Epoxy a proprietary lining product available to only one domestic U. S. ductile iron pipe company?
No. PROTECTO 401™ is made by the Induron Company and is available and sold by all domestic manufacturers of ductile iron pipe.
FAQ: Is PROTECTO 401™ a toxic material? Is it harmful to human or animal health?
Using Environmental Protection Agency (EPA) Method 1311 – Toxicity Characteristic Leaching Procedure, cured films of PROTECTO 401™ were tested and found not to leach any amount exceeding that allowed by EPA for the 32 toxic substances listed in that procedure. Based upon that testing and a literature search, it has been determined that PROTECTO 401™, when used as recommended to protect sewer lines against corrosion, does not present a health hazard to humans or any risks to the environment.
FAQ: Is PROTECTO 401™ suitable for potable water applications?
No. PROTECTO 401™ lined pipelines are not suitable for conveying potable water.
FAQ: Is PROTECTO 401™ able to resist sulfuric acid concentrations and ordinary household chemicals found in the most septic of domestic sewage applications?
Development of PROTECTO 401™ began in 1979, with the first PROTECTO 401™ lined project for domestic sewage service in 1981. Ongoing testing of PROTECTO 401™ lined samples in accelerated simulated sewer environments, coupled with the service history of hundreds of miles of PROTECTO 401™ lined pipe without one known lining failure, gives ample evidence of its ability to resist even the most septic of domestic sewage.
FAQ: What are the flow characteristics of PROTECTO 401™?
The flow characteristics of PROTECTO 401™ lined ductile iron pipe are equal to or better than cement mortar lined ductile iron pipe. For open channel or partially full gravity pipelines a Manning flow coefficient of n = 0.011 is used. For full-flowing pressure pipe, a Hazen-Williams flow coefficient of C = 140 is used.
