UNI Flanges

Dimensions: 1/2”, 2”, 3”, 4”, 6”, 8”, 10”, Customized up to 60”
Material: Carbon, Alloy and Stainless Steel
Thickness: Schedule 10(S) to SCH 160
Standard: ASME, ANSI, DIN, JIS, EN etc
Class Range: Class 150 to 2500 (# or LB). PN 2.5 to PN 250.
Flange Face Type: RF, FF, MFM, TG, RJ
End: Bevel end
Connection: Butt weld
Manufacturing Process: Forging
The weld neck flange features a long tapered hub for butt welding, ensuring strong structural integrity and excellent stress distribution. It minimizes leakage risks, ideal for high-pressure, high-temperature, and critical service applications.
It complies with standards like ANSI/ASME B16.5, DIN, EN 1092-1, and GOST , available in PN6-PN160 and DN15-DN5000, with materials including carbon steel, stainless steel, and alloy steel.
Widely used in oil and gas, petrochemical, power generation, and chemical processing industries.
