Jul 07, 2010 Arthur, As the copper saturates the PM solution, the PMs are cemented and copper I chloride off white to gray colored is precipitated as the acid levels drop. Add some 31 muriatic acid to the white powder and see if it dissolves. Not sure about the brown sludge, but it sounds like an iron compound to me.

A kinetic investigation of copper cementation in a revolving drum was undertaken by the Bureau of Mines to explore the effects of a porous copper deposit attached to the iron surface and a fluidized slurry of copper particles surrounding the iron precipitant. The rate of cementation was found to be significantly enhanced by the increased cathodic areas provided by a porous copper deposit or the p
Out-of-sight, out-of-mind. Thats the phrase that comes to mind for all who have installed copper and copper alloy piping systems in buried, underground applications. An expectation well supported by the excellent corrosion resistance of copper alloys used in these applications. An expectation that may not be realized when this out-of-site, out-of-mind philosophy extends to the practices used ...
Apr 26, 2018 Copper has a relatively high melting point of 1,083 degrees Celsius 1,982 F, but if you have the right equipment, you can melt it at home. Melting Copper With A Blowtorch Use a wire cutter to remove any outer insulation coating, as this is toxic when burned.

Corrosion of Embedded Metals. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling.
Mar 07, 2012 Copper to PVC is NEVER bonded with PVC cement, so your basic premise is faulty. YOU can use anything you want to, but WE will NOT tell you it is proper or will last a lifetime , or even that it is NOT leaking once you set the base in place. hj, Dec 5, 2011 6. jimbo Plumber. Joined
Jun 18, 2012 Roberta walked us through the steps involved in making the concrete leaves, including mixing the concrete, adding colorant, mounding sand, choosing leaves, working with the underside of the leaf, building up the concrete, smoothing the bottom with a brush, and adding a copper fitting if we wanted to put our cast leaf on a copper pipe pedestal, for a raised bird bath or feeder.

You can connect PVC or CPVC to copper in several ways. One common method is to solder a female threaded fitting onto the copper pipe, screw in a male threaded plastic fitting and finish up by gluing plastic pipe to the plastic fitting. This isnt the best way, though, because you cant tighten the fitting if
