ELBOWS
Large Stock & Rapid Production
TItanium Elbow
Titanium Elbows, manufactured in accordance with ASME B16.9 are pipe fittings sized between 0.5 inch to 48 inch. Used to connect pipes and piping sections together, precision engineering ensures that the integrity of the pipe structure.
We manufacture to the full range of ASME B16.9 sizes in a range of titanium grades as detailed below. If you would like to discuss your piping project or simply need a quick quote for parts, big or small, we’d love to hear from you!
ASME B16.9 Standard
The ASME 16.9 elbow standard defines dimensions of a small to medium size range of piping applications. The standard also covers a range of materials and the production techniques. Whilst the standard serves the majority of cases custom sizes can also be produced.
The B16.9 standard defines two types of elbows, short and long radius. Long radius elbows are used to reduce pressure changes within the piping. Short elbows are the more conventional sizes.
