Our advanced Nu Line Epoxy Barrier Coating technology is available to Nu Flow Licensees, homeowners, business owners and government entities.
This simple but highly effective pipe restoration system uses cured-in-place (CIP) technology to quickly and completely coat the inside of copper or galvanized pipe.
The process stops and prevents future leaks while protecting against waterborne contaminates, such as lead, which can leach into piping systems over time.
Epoxy pipe lining restoration of plumbing, structural pipe and mechanical systems is a non-invasive process that uses epoxy to coat the inside walls of pipes without destruction to interior or exterior surfaces of building structures, hardscape or landscape.
Nu Line, Nu Flow’s top of the line epoxy lining system, is used not only as a long-term solution to prevent corrosion and leaks, but is commonly used as a preventative tool to preserve the life of existing piping systems.
Nu Flow manufactures our own epoxies and guarantees the highest possible quality control standards.
Our potable water epoxy meets or exceeds all industry standards for safety and performance. The life expectancy of the epoxy is estimated to be 100 years and has withstood the test of time for more than 40 years in Japan, and almost 25 years in the United States.
Nu Flow is master licensee of the U.S. Navy’s patented ‘702 epoxy and lining process, and operates under two Nu Flow drain lining patents and seventeen industry-related patents.
Pipe Degradation Timetable
Quick fact: Since the 1970’s, the mandatory addition of chemicals to drinking water causes pipe failure in above ground and below ground piping systems in as little as 5 to 10 years of service.
Metal piping systems begin to deteriorate from the moment they are put into service. Here’s a snapshot of estimated deterioration rates, prior to the chemical additive crisis.
40 + years
1950’s – 1960’s
20 – 30 years
Causes & Factors
Corrosion rates in metal pipes have increased greatly due to chemical additives, high oxygen, higher water temperatures and low water pH.
Inferior plumbing techniques and poor piping design can cause erratic water flow patterns that accelerate spot corrosion and cause fractures and other problems.
The corrosion and erosion of pipe walls result in pinhole leaks that, over time, will appear throughout the entire piping system. Undetected, these ‘small problems’ can cause catastrophic water damage and mold growth over time.
Epoxy Lining Benefits
Safe & Durable – Nu Flow’s epoxy is UL certified safe to NSF/ANSI Standard 61. The epoxy was developed and patented by the U.S. Navy and has been successfully applicated by Nu Flow technicians since the mid-1980s for the U.S. government and in domestic, commercial, industrial, and other applications. Testing engineers estimate the life expectancy of the epoxy is roughly 100 years.Epoxies for drain, sanitary and storm lines meet or exceed the physical properties set forth in ASTM F1743 for CIPP rehabilitation and ASTM F1216 for Inversion rehabilitation.
Cost Effective – Pipe lining is as much as 50 percent less expensive than traditional pipe replacement costs such as repiping. Lining is a non-invasive process, so there is no destruction to buildings, hardscape or landscape. Reconstruction costs for repiping are as much as 60 percent of direct pipe repair costs and epoxy lining eliminates the need for reconstruction.
Minimal Downtime – The epoxy lining process takes a fraction of the time of traditional repipe methods. For example, a repiping job that would normally take a full 6 to 8 weeks can take as little as two weekends (or 4 days) for Nu Flow to complete.
Minimal Disruption and No Occupant Displacement – Nu Flow’s pipe restoration process is quick, quiet, non-invasive, and requires no displacement of a building’s occupants. When needed, temporary bypass water systems are quickly installed to provide uninterrupted water service so that occupants, businesses, and clientele may continue business as usual in an undisturbed environment.
Versatility in Applications – Epoxy lining can be performed in any metal pipe in any building, structure, or environment, above or below ground. Nu Flow technicians have restored piping systems for hotels, high-rise condominiums, hospitals, restaurants, airports, schools, museums, U.S. Navy ships and many other commercial and industrial companies using Nu Flow technologies.Nu Flow epoxy liners are available potable water pipes as well as hot water recirculation systems, fire sprinkler and fire suppression systems, chiller lines and HVAC systems.
Environmentally friendly. Our epoxy pipe lining creates no waste for landfills or for recycling and generates no carbon emissions during manufacturing, making it an eco-friendly solution.Nu Flow epoxy lining also prevents heavy metals from leaching into drinking water and stops leaks and breaks in sanitary lines that pollute watersheds and seep pollution into groundwater.
