Metallic Zinc Coating for Ductile Iron Pipe

Zinc metallizing with a high purity zinc wire has been utilized for external corrosion control of iron pipe for over 50 years, and supplied by U.S. Pipe for over 20 years.. While most publications on metallic zinc coated iron pipe are based on experience and case histories from England and Europe, it should be noted that metallic zinc is, and has been used extensively for external corrosion protection of ductile iron pipe by China, India, the Middle East, Latin America, Africa, Korea, Japan, and others. Zinc coating for external corrosion protection of ductile iron pipe is such a recognized and established worldwide practice that there is an international standard, ISO 8179-1(Ductile Iron Pipes-External zinc-based coating-Part 1: Metallic Zinc with Finishing Layer) which was first issued in 1985 (ISO, 2004).
