Ratio of max pit depth to average metal loss. >3 indicates problematic pitting.
: The standard covers the material selection, manufacturing, testing, and inspection of cast and wrought corrosion-resistant alloys. It is designed for use by material suppliers, manufacturers of equipment, and users of equipment in petroleum and petrochemical services.
(now AMPP SP0775 ) is the definitive standard for monitoring internal corrosion in oilfield operations using metallic coupons. First established in 1975, it provides a uniform framework for preparing, installing, and analyzing weight-loss coupons to evaluate the corrosiveness of oil, water, and gas handling systems. Core Purpose and Scope
: The use of high-quality CRAs that are properly inspected and tested can lead to significant cost savings by minimizing the need for repairs, replacements, and downtime.
AMPP (merger of NACE and SSPC) now maintains SP0775. Always check the latest revision.
