Titanium Grade 2 (UNS R50400) Seamless Pipes
Commercially Pure Grade 2 titanium pipes offering lightweight strength, non-magnetic properties, and lifetime corrosion resistance in marine environments.
ASTM B861 / ASTM B338 Grade 2 CP Titanium Pipe & Tube
Starlight Tubes is a specialized manufacturer of Titanium Grade 2 (UNS R50400 / DIN 3.7035) seamless and welded pipes. As the most widely utilized commercially pure titanium grade, Grade 2 delivers exceptional resistance to seawater, brine, wet chlorine gas, chlorates, and organic acids, making it essential for critical marine and chemical plants.
Our Grade 2 titanium pipes are manufactured with strict inert-gas shielding to ensure high purity and ductile forming properties. Every pipe undergoes ultrasonic testing, pneumatic/hydrostatic pressure testing, and complete chemical gas analysis (C, O, N, H, Fe).
