Quality Production and Testing

NUCO V-Band Couplings can be paired with NUCO Sheet Metal Flanges, NUCO Machined Flanges, or flanges cast as an integral part of your product. National Utilities has the capability to custom manufacture flanges in our modern Fort Worth production facility, complete with the finest equipment and tooling capabilities.

Sheet Metal Flange

Every NUCO Sheet Metal Flange is hydraulically formed using a radial-axial bulge forming process known for accuracy and consistency. We create flanges from corrosion-resistant 300 series stainless steel, nickel alloys, Inconel, A-40 or A-70 commercially pure titanium, and aluminum. These lightweight flanges provide hot-air duct joints where a low leakage rate is permissible, and do not require gaskets because of the metal-to-metal seal at the sheet metal flange face. NUCO Sheet Metal Flanges are readily available in standard tube sizes of 1 to 10 inches.

Machined Flange

Manufactured for higher performance applications, NUCO Machined Flanges feature the profile and metal combinations that will ensure proper seals for the application at hand. Take a look at our flange selection guide for an idea of our capabilities, and remember that National Utilities manufactures high-performance machined flanges for almost any specific customer requirements.
