Description
The Titanium Gr12 Elbow (ASME B16.9) is a pipe fitting used to change the direction of
flow in a piping system. Depending on the design, elbows can
redirect flow upward, downward, to the left, right, or at custom
angles.
The long radius (L/R) elbow has a centre-to-end dimension of 1.5D, equal to 1.5 × NPS (Nominal Pipe Size) in inches. According to ASME B16.9, standard long radius elbows are typically available in 90° and 45° configurations.
Titanium Grade 12 (Ti-0.3Mo-0.8Ni) offers superior corrosion resistance, strength, and high-temperature performance, making these elbows suitable for demanding industrial
applications.
