Corrosion is a leading cause of pipeline failures, but material selection can drastically reduce risks. API 5L pipes with PSL2 certification provide robust protection against sour gas, while galvanized coatings shield water pipes from rust. Carbon steel, though economical, requires additional treatments for acidic or saline conditions. This analysis compares anti-corrosion properties of ERW, seamless, and casing pipes in settings like offshore rigs, wastewater plants, or coastal infrastructure. Learn how to apply coatings, cathodic protection, or alloy adjustments to extend service life, minimize maintenance, and comply with safety standards across diverse industrial applications.
