Polished Titanium Welded Neck Flange Ti6Al4V
Polished Titanium Welded Neck Flange Ti6Al4V
Titanium flanges are widely used in industries that require resistance to corrosion, such as chemical processing, petrochemical, oil and gas, marine, and aerospace, and are particularly suitable for aggressive environments, high temperatures and high-pressure conditions. This polished weld neck flange is forged and CNC machined in Ti6Al4V (Gr5), Gr2 and other grades with a raised face sealing surface.
