Sep 17, 2018 · The thought is that both SS and galvanized steel are corrosion-resistant and the mechanical coupling provides a dielectric separation, which is incorrect. The dielectric corrosion that occurs between the galvanizing (zinc) and the SS is extreme because the materials are at nearly opposite ends of the metal nobility chart. Consulting - Specifying Engineer Selecting pipe and Sep 17, 2018 · The thought is that both SS and galvanized steel are corrosion-resistant and the mechanical coupling provides a dielectric separation, which is incorrect. The dielectric corrosion that occurs between the galvanizing (zinc) and the SS is extreme because the materials are at nearly opposite ends of the metal nobility chart. Corrosion Plumbing Piping - PHCP ProsDec 05, 2016 · The paragraph on dielectric fittings describes dielectric fittings as a combination fitting of copper alloy and ferrous materials with threaded, solder joint, plain or weld-neck end connections that match piping system materials. It calls for an insulating material suitable for the system fluid, pressure and temperature application.

Dielectric flanges are installed between pipes made from dissimilar metals to help prevent accelerated deterioration and corrosion. Each includes a union nut, 2 tailpieces, and a gasket. They are ideal for use in air and water conditioners, hot water storage tanks, Dielectric Unions and Flanges - Pipe Fittings - Grainger Dielectric flanges are installed between pipes made from dissimilar metals to help prevent accelerated deterioration and corrosion. Each includes a union nut, 2 tailpieces, and a gasket. They are ideal for use in air and water conditioners, hot water storage tanks, Dielectric union requirements - Pipelines, Piping and Apr 09, 2008 · Thank you both for the leads. The website was very helpful, and it appears as though the joint between copper pipe (V = 0.35) and stainless steel pipe (304 SS has +/- 18% chromium content, so V = 0.50) will NOT require a dielectric union, since the differnece is only 0.15.
Also be aware that directly joining two different types of metals, in this case, galvanized steel pipe and copper, can cause rapid corrosion at the joint (called dielectric corrosion). To limit this problem, make the steel/copper connections with special dielectric unions rather than with a regular coupling. Legend Valve Plumbing, Industrial, Commercial, Hydronics Legend provides high quality valves and fittings for plumbing, industrial, commercial and residential markets.

A plastic sleeve prevents destructive corrosion when connecting different metals. Pipe is also known as Schedule 40 and is designed for low-pressure applications. It is galvanized steel, which has fair corrosion resistance. Pipe is welded, so there is a weld bead on the inside. Not for use in heating systems that use hot liquids or gas..
