Forged Titanium Weld Neck Flange Class 1500
Forged Titanium Weld Neck Flange Class 1500
A flange is a detachable connection in which the flange, gasket and bolts form a combined sealing structure. Flange connections are widely used in pipeline construction because they are easy to assemble and can withstand high pressure. This forged weld neck flange is produced by forging and CNC machining in Gr2, Gr5, Gr11 and Gr12 titanium to ANSI, ASME, DIN and JIS standards.

Flange Types & Standards
| Type | Description |
|---|---|
| Welding neck (WN) | Long tapered hub welded to the pipe, preferred for high pressure and severe service |
| Slip-on (SO) | Slides over the pipe and is fillet welded, a low cost general purpose type |
| Blind (BL) | Closes a pipe end or valve opening |
| Socket welding (SW) | Used on small diameter high pressure lines |
| Threaded (TH) | Used where welding is not practical |
| Plate flat (PL) | Simple flat flange for low pressure service |
Sealing Faces & Pressure
| Sealing Face | Code | Typical Use |
|---|---|---|
| Raised face | RF | General high pressure pipeline service |
| Male and female | MF | Gasket located in the female groove |
| Tenon groove surface | TG | Large diameter connections |
| Metal ring joint | RJ | Very high pressure and temperature lines |
Applications & Flange Advantages
These flanges are used in petrochemical, medical and healthcare, power, aerospace, metallurgy, marine, gas and environmental protection systems that require high pressure connections. Titanium offers a long service life, corrosion resistance and high yield and tensile strength, which keeps the joint reliable in aggressive media.
