Water Treatment System And Pressure Pipe Therefor
US Patent:
7429323, Sep 30, 2008
Filed:
Apr 27, 2005
Appl. No.:
11/116025
Inventors:
Richard E. Deremiah - Centerville OH, US
Assignee:
Price Brothers Company - Dayton OH
International Classification:
C02F 1/78, F16L 9/08
US Classification:
210192, 210199, 210254, 210418, 138109, 138145, 138155, 138175
Abstract:
A pressure pipe for transporting corrosive material, such as ozonated water, is formed with a pipe joint that is resistant to ozone. An intermediate portion of the pressure pipe is formed from a low-carbon steel cylinder with inner and outer concrete layers and prestressing wire. A stainless steel slip joint member is attached to an end of the low-carbon steel cylinder to facilitate joining adjacent pipe sections. The stainless steel slip joint members resist the corrosive effects of ozone, while the inner concrete layer protects the low-carbon steel cylinders of the intermediate portion. In one aspect of the invention, a water treatment system constructed from pressure pipe as described above is connected as a bypass loop to a primary pipe run from a water source to a treatment plant. Ozone is introduced to water diverted through the bypass loop. The water decomposes prior to being reintroduced back into the primary pipe run.
Testable Pipe Joint
US Patent:
2004017, Sep 9, 2004
Filed:
Mar 3, 2003
Appl. No.:
10/378487
Inventors:
Richard Deremiah - Dayton OH, US
Assignee:
Price Brothers Company
International Classification:
F16L049/00
US Classification:
285/230000
Abstract:
A locking ring-type pipe joint has a spigot ring provided on a first pipe section, a bell ring provided on a second pipe section, and a locking ring that may be contracted to engage the spigot ring to the bell ring. First and second circumferential grooves formed in the spigot ring are configured to receive a test gasket and a pipe seal gasket respectively. An annular test space between the gaskets is in closed connection with a pressure port, whereby the pressure seal of the pipe seal gasket may be evaluated after the pipe sections are joined and prior to activating the joint restraint feature, installing the next pipe, and back-filling the pipe sections.
