Description

Product material

Inconel Alloy 625 control lines and welded coiled tubes are engineered for high performance in extreme environments, offering exceptional resistance to oxidation, pitting, and crevice corrosion. Made from nickel-chromium-molybdenum alloy, Inconel 625 provides excellent strength and resilience in temperatures ranging from cryogenic to 982°C (1800°F). These tubes are well-suited for critical applications in demanding industries, particularly where exposure to harsh chemicals or high-pressure systems is common.
