Corrosion resistance of duplex 2205 pipe is better than 304 stainless steel pipe, with good corrosion

Corrosion resistance of duplex 2205 pipe is better than 304 stainless steel pipe, with good corrosion resistance in the production of pulp and paper. Moreover, 316 stainless steel is also resistant to erosion by marine and aggressive industrial atmospheres. 316 stainless steel has good oxidation resistance in intermittent use below 1600 °C and continuous use below 1700 °C. In the range of 800-1575 degrees, it is preferable not to continuously apply 316 stainless steel, but when 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better carbide precipitation resistance than 316 stainless steel and can be used in the above temperature range. Annealing is carried out at a temperature ranging from 1850 to 2050 degrees, followed by rapid annealing and rapid cooling. 316 stainless steel cannot be hardened by heat treatment. 316 stainless steel has good welding properties. All standard welding methods can be used for welding. When welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding according to the application. For best corrosion resistance, the weld...

New York American Water to install new pipes in Woodmere | Herald Community Newspapers

A $570,000 project to install new water main piping along Elm and Pine streets in Woodmere began on March 5, according to New York American Water officials. The project will replace 1,250 feet of four-inch water main installed in the early 1900s with new eight-inch ductile iron water main, officials said. The work also calls for the replacement of four hydrants and 34 utility-owned service lines. Main replacement will take place along Pine Street from Central Avenue to Cedar Lane and along Elm Street from Broadway to Cedar Lane. That began on March 5. Each project is expected to take roughly four weeks to complete. Final street restoration will follow nearly a month after the services have been installed and pass all required tests from the Nassau County Department of Health. “Replacement of two stretches of water main along Pine Street and Elm Street will help improve water quality, service reliability and water pressure in the area,” New York American Water Manager of Engineering John Kilpatrick state in a news release. New York American Water will coordinate with residents along Elm and Pine streets to minimize disruptions. Work will take place between the hours of 8 a.m. an...
