2. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   A galvanized coating of metallic zinc was often used to protect steel water pipes from corrosion, but this protective coating eventually would dissolve away, exposing the iron to deterioration. Pipes used to convey fuel gas are often made of "black iron", which has been chemically treated to reduce corrosion, but this treatment does not resist ...

3. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   These plaques can flake off, leading to visible impurities in water and a slight metallic taste. The life expectancy of galvanized piping is about 40–50 years, [12] but it may vary on how well the pipes were built and installed. Pipe longevity also depends on the thickness of zinc in the original galvanizing, which ranges on a scale from G01 ...

4. Deep freeze breaks pipes, creates water crisis across South - AOL

   Days of freezing temperatures in Deep South areas that usually freeze for only hours are threatening dozens of water systems as burst pipes leak millions of gallons of water. The problems were ...

   en.wikipedia.org/wiki/Lead_contamination_in...

   While performing research into premature pipe corrosion for the District of Columbia Water and Sewer Authority (WASA) in 2001, Marc Edwards, an expert in plumbing corrosion, discovered lead levels in the drinking water of Washington, D.C., at least 83 times higher than the accepted safe limit.

   At least a third of Oshkosh’s 21,500 water service lines are still yet to be identified as the Department of Public Works hopes to have all the city’s lead pipes replaced by 2025.

7. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

8. Plumbing - Wikipedia

   en.wikipedia.org/wiki/Plumbing

   Old water pipe, remnant of the Machine de Marly near Versailles, France. Lead was the favoured material for water pipes for many centuries because its malleability made it practical to work into the desired shape. Such use was so common that the word "plumbing" derives from plumbum, the Latin word for lead.

9. Pipe-in-pipe system - Wikipedia

   en.wikipedia.org/wiki/Pipe-in-pipe_system

   Internal pipes can be seen entering the external pipes in the bottom of the cabinet. In case of an internal leak, water will overflow through the external piping and can be detected inside the cabinet. A pipe-in-pipe system [1] is a form of plumbing where all water pipes are running inside another pipe. Its purpose is to ensure that any leaks ...
