Duplex Steel Stud Bolts are used to secure flanged joints in pressure vessels, heat exchangers, pipelines, and reactors. Their high strength and corrosion resistance make them ideal for marine engineering, chemical processing plants, offshore platforms, and refineries. They provide secure, leak-proof connections even in extreme temperatures or pressures. These bolts are preferred for applications involving harsh chemicals, seawater exposure, and mechanical vibrations. Their durability reduces maintenance intervals and boosts structural integrity, making them essential in high-risk industrial setups where failure is unacceptable.
