  • Pipe Repair On A Budget
    Key Pain Points Just with repairs alone each day 657 water main breaks occur in North America at a total annual repair cost of over 3 billion The magnitude of the problem is further evidenced as follows The EPA estimate for corrosion cost on US water lines is 4 4 5 0 billion per year and growing The EPA s 2011 drinking water infrastructure needs survey cited the need in aggregate for the municipal sector to invest about 384 billion in the upcoming 20 years to maintain existing infrastructure quality Let s take this one step further 1 Costs and Time Pipe joining methods are expensive requiring extensive labor equipment and installation time The average crew time for current ranges from 7 150 minutes depending on bevel diameter 2 Safety As noted industry standard installation and repair procedures for joining pipelines are unsafe and OSHA prohibited 3 Corrosion The EPA estimates 4 000 5 000 miles of annual drinking water pipe replacements each year and this is projected to peak in 2035 at 16 000 to 20 000 miles each year Repair Practices To Date There are currently three methods for providing corrosion control for ductile iron piping systems 1 polyethylene encasement sleeve poly wrap 2 adding complex and expensive cathodic protection devises 3 doing nothing and incurring the increased costs and the effects of corrosion Of these three doing nothing has been the most common method employed until such time that a pipe breaks Poly wrap is the recommended solution for mitigating corrosion but it has a reputation for poor performance due to rips and tears that can occur during installation The other methods address corrosion but elevate safety hazards and are far more expensive time consuming and less reliable solutions A New Solution Infra Tect is focused on developing and selling products that deliver a lower cost of installation operations maintenance and repair for water and wastewater infrastructure piping systems We have designed and patented ground breaking product innovations for utility systems The Bevel Sert our initial product is patented and proven to improve ductile iron pipe water infrastructure DIP by greatly reducing the time and money spent on new installation and repairs improving installation safety and reducing corrosion In fact the Bevel Sert is easy to install 1 minute to install saves 50 89 in installation costs eliminates the OSHA prohibited beveling practice and significantly reduces the pipe s ability to conduct electricity which reduces the corrosion process by up to 99 Made from HDPE the Bevel Sert is suitable for use in potable water applications where the outside diameter of the pipe is the same as ductile iron pipe The size range is 4 to 48 in diameter The HDPE bevel is smooth finished to allow for use with all types of rubber gaskets including restrained joint rubber gaskets The rounded bevel compensates for differing angles of deflection which can frequently occur during installation Considering the high benefit to cost ratio for utilizing the Bevel Sert
