    Describes an external protective coating system which is factory applied to ductile iron pipeline components as specified in ISO 2531, ISO 7186 and ISO 16631.

    Scope - (Show below) - (Hide below)

    This document specifies an external protective coating system which is factory applied to ductile iron pipeline components as specified in ISO2531 , ISO7186 and ISO16631 . This coating system comprises an electro-deposited metallic zinc-based coating of

    • pure metallic zinc with a purity of 99,99%,

    • zinc and aluminium alloy with or without other metals, or

    • other zinc alloys

    followed by a finishing layer that can be bituminous paint or synthetic resin compatible with zinc-based coating.

    NOTE ISO8179‑2 deals with zinc-rich paint coating.
