Bevel-Sert Reduces Corrosion by Making Underground Piping Electrically Discontinuous HDPE Beveled Edge Has the Potential to Save Municipalities Significant Infrastructure Repair Expenses

(Phoenix, Az. April 21, 2011) – If you were to look at the average water pipe running under the ground, you would inevitably find some level of corrosion, from a minimal amount to the pipe being on the verge of breaking. This corrosion can affect the quality of the water and the lifespan of the pipe. The Bevel-Sert, an HDPE beveled radius developed by Infra-Tect, connects two ductile iron pipes and reduces the corrosion potential by increasing the electrical discontinuity between the pipe segments to a level of no more than 9%.

Another issue with older pipes is that they can burst at any time, causing hundreds of thousands of dollars in damage. According to an article in The New York Times, water mains installed across the country 70-200 years ago are bursting with alarming regularity. There are an estimated 240,000 water main breaks each year in the United States, according to the Environmental Protection Agency’s Aging Water Infrastructure Research Program. The article also draws attention to the cost involved with upgrading the nation’s infrastructure:

The new federal stimulus law provides $6 billion for water projects, with $2 billion of that directed to drinking-water systems. But that money is only, well, a drop in the bucket: a report released last month by the E.P.A. estimated that the nation’s drinking water systems require an investment of $334.8 billion over the next two decades, with most of the money needed to improve transmission and distribution systems.

Currently, workers are using a cut-off saw to bevel the edges of pipes to join them, a practice which is both dangerous and prohibited by OSHA regulations. Because the two pipes are directly connected, electro-connectivity will naturally occur from the moment the pipes are installed. Other issues can affect the rate at which corrosion occurs, including chemicals in the soil, the quality of the pipes, electrical current, and water. The Bevel-Sert mitigates all of these issues, extending the lifespan of most underground pipes up to 11 times by isolating each pipe segment at the joint.

How does the Bevel-Sert accomplish this? Because it is made of high-density polyethylene (HDPE), the chemical reaction that causes corrosion is abated and the current cannot pass from one joint to the next. The Ductile Iron Pipe Research Association states that there are “long-line corrosion cells,” which occur due to the accumulation of electrical current passing up and down the pipe line—-but this can be eliminated by making joints that are not bonded or by making them electrically isolated. That is exactly what the Bevel-Sert does.
