Galvanizing ~ The process of applying a coating of zinc to the finished product to provide corrosion protection. The coating can be applied by hot dipping or electrolytic deposition. Paul McElrath - Steam PipingElectric Resistance Weld Pipe (ERW) ~ Cold finished pipe made by a series of operations in which the flat rolled material is cold shaped into tubular form and welded at the seam. The heat for the weld is generated at the seam by the resistance to the flow of electric current applied through electrical contacts or an induction coil.Galvanic Action ~ The phenomenon of corrosion of an anode (positive terminal - like on a battery). When two dissimilar metals are immersed in an electrolyte, an electrical potential will exist between them. If the two are in an electrical contact, a current will flow. The metal that becomes the anode (negative) of this cell will corrode and dissolve while the cathode (positive) will be protected from corrosion. Clevis Hanger ~ A type of pipe hanger with a swivel yoke supported at the top by an adjustable vertical rod. This yoke bolts to pin holding a U-strap of metal (clevis) that supports the pipe. Paul McElrath - Install PVC Pipe : Siphoning ~ The suction or pulling effect that takes place in the trapway of a toilet as it is filled with outgoing water and waste.
