Stainless Steel and CRA Seamless Tubes: High-Quality Products for High-Quality Markets

摘要

Corrosion Resistant Alloys (CRA) pipes represent a growing market niche, but one with high profitability. Among the most important applications for CRA pipes, is OCTG (Oil Country Tubular Goods). One of the main drivers in the OCTG market is the development of unconventional resources, like shale gas, shale oil, and tight sands. Deep-well, high-temperature and pressure, sour and high-corrosion environments increasingly require the use of highly sophisticated materials such as CRA. In these cases, the market volume is relatively low but concentrated in some specific areas.The demand for seamless tubes calls for martensitic steel with a 13% Cr content as the prominent alloying element, duplex and super duplex grades, austenitic steel with a Cr content of 28% and more, and nickel-, titanium-, and zirconium-based alloys. CRA pipes are also widely used in processes involving highly corrosive fluids and gases (boilers, chemical processing, condenser systems, and refineries). Other typical applications are heat exchangers and precision tubes.High-end products mean high profitability and margins with a faster ROI, but cutting-edge technical knowledge represents a significant barrier to market entry.
