Titanium Alloy Flange ASTM B16.5 Gr2 Gr7 Gr12
Titanium Alloy Flange ASTM B16.5 Gr2 Gr7 Gr12
Titanium flanges connect pipes, valves and equipment in chemical, petrochemical, power and water treatment systems. A flange joint combines two flanges, a gasket and a set of bolts and nuts; tightening the nuts deforms the gasket so that it fills the uneven areas of the sealing face and forms a tight, leak proof connection. This titanium alloy flange is forged and CNC machined in Gr2, Gr7 and Gr12 with a polished raised face RF finish, giving a light, corrosion resistant joint that holds under high pressure.
