CRA BASICS: Material Handling

/ /
While duplex stainless steels, austenitic stainless steels, and nickel-based alloys are naturally resistant to atmospheric corrosion in most industrial environments, improper handling of these alloys may result in compromised material performance. Without special care, corrosion may result from surface damage or contact that often occurs during storage or transportation.

What Are Corrosion Resistant Alloys?

Corrosion resistant alloys are metals engineered to resist degradation by oxidation or other chemical reactions. The most common cra’s, used for mild to moderate corrosion resistance, are stainless steels. Stainless steels are iron-based alloys containing a minimum of 10.5% chromium, which is sufficient to prevent rust under typical room temperature atmospheric conditions. Stainless steels simply […]

What Are The Key Completion Design Considerations For CRA vs. GRE Lined Tubulars?

Regular API 5CT carbon Steel OCTG is fitted with a Glass Reinforced Epoxy (GRE) inner tube for an economical OCTG purchase option for corrosive, aggressive, and normal environments in both production and injection wells. GRE pipe technology is well used throughout the industry and is a Discontinuous Filament Winding process using high-strength fiberglass and amine […]
