Titanium Grade 2 Pipe Fittings – Buttweld, Forged & Olet Types – ANSI/ASME Compliant – Worldwide Delivery.
We are a globally recognized manufacturer and supplier of Titanium Grade 2 pipe fittings, flanges, forged fittings, and branch outlets, engineered to meet the most demanding industrial requirements. With decades of expertise in supplying corrosion-resistant materials, our Titanium Grade 2 products are widely used in industries such as chemical processing, desalination, marine engineering, pulp & paper, and heat exchanger systems. The alloy’s excellent corrosion resistance, lightweight properties, and formability make it a preferred choice for critical piping systems under aggressive environments.
Our product portfolio includes Titanium Grade 2 buttweld fittings (elbows, tees, reducers, caps, stub ends), forged fittings (socket weld & threaded types such as couplings, unions, bushings), flanges (WNRF, SORF, BLRF, threaded, and lap joint), and outlet fittings (Weldolet, Sockolet, Threadolet, Elbolet). All components are manufactured as per international standards such as ASME B16.5, B16.9, B16.11, and MSS SP-97. Raw materials conform to ASTM B363 for buttweld fittings and ASTM B381 for flanges and forged products. Sizes range from ½” NB to 24” NB, with pressure classes from 150# to 600#.
Titanium Grade 2 (UNS R50400) is an unalloyed titanium offering excellent corrosion resistance in oxidizing and mildly reducing environments. It provides high strength-to-weight ratio, good weldability, and outstanding biocompatibility. The material has a tensile strength of approximately 344 MPa and excellent elongation, making it ideal for applications requiring ductility and resistance to seawater or chemical attack. Every product undergoes stringent quality control checks, including PMI testing, hydrotesting, ultrasonic testing, and visual inspection, under an ISO 9001:2015-certified system.
All Titanium Grade 2 fittings, flanges, and outlet products are securely packed using export-worthy materials like fumigation-treated wooden boxes or crates, with end caps and polyethylene protection to prevent damage during transit. We offer quick lead times, competitive pricing, and global shipping to over 60 countries across Europe, the Middle East, Southeast Asia, and North America. With strong inventory and reliable sourcing, we support urgent project requirements and long-term procurement needs alike.
Titanium Grade 2 Fittings & Flanges – Including ASME-Compliant Forged & Buttweld Types, Weldolet, Sockolet, Threadolet – Sizes from ½” NB to 24” NB, Class 150# to 600#.
