Ismail Flanges is your go-to manufacturer and supplier of Titanium Lap Joint Flanges right here in Jakarta, Indonesia. We pride ourselves on crafting precision-engineered flanging solutions that are perfect for applications needing top-notch corrosion resistance, lightweight strength, and easy disassembly. Our titanium lap joint flanges are typically paired with stub ends and are a favorite in systems that require frequent take-downs. Built to endure harsh chemical, marine, and high-temperature conditions, our flanges deliver outstanding durability and performance. At Ismail Flanges, we make sure all our products meet international standards, providing reliable and cost-effective solutions for critical fluid handling and pressure systems.
Our Titanium Lap Joint Flanges are crafted from commercially pure titanium (Grade 2) or titanium alloys like Grade 5 (Ti-6Al-4V). These materials contain at least 90% titanium, with some aluminum (up to 6%) and vanadium (up to 4%) added in. Thanks to their excellent corrosion resistance, these flanges thrive in chloride and acidic environments. When it comes to mechanical properties, they boast tensile strength from 345 MPa (Grade 2) to 950 MPa (Grade 5), yield strength ranging from 275 MPa to 880 MPa, and elongation between 15–30%. Plus, they’re lightweight, weldable, and maintain impressive structural integrity even under changing temperatures and pressures.
