A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
Materials for Flanges
Zuudee Special flanges are manufactured in all the special materials like titanium(3.7035,3.7164/3.7165),hastelloy series(c276,B2,B3),inconel series(600,625,718),incoloy series(800,825),monel series(400,k500) etc. And the most used materials is forged titanium alloys and have machined surfaces.
All flanges, produced by Zuudee fall under the ASME en ASTM standards, unless otherwise indicated. ASME B16.5 describes dimensions, dimensional tolerances etc. and ASTM the different material qualities.For DIN Standards,please check with our engineers.
Types of Flanges
The most used flange types in Zuudee Flanges are:
•Welding Neck Flange
•Slip On Flange
•Socket Weld Flange
•Lap Joint Flange
•Threaded Flange
•Blind Flange

Except the most used standard flanges, there are still a number of special flanges such as:
•Orifice Flanges
•Long Welding Neck Flanges
•Weldoflange / Nipoflange
•Expander Flange
•Reducing Flange

Pressure Classes of Flanges
Forged Zuudee flanges, according to ASME B16.5, are made in seven primary ratings:
| Class | 150 | 300 | 400 | 600 | 900 | 1500 | 2500 |
| Diameter – A | 30 | 38 | 38 | 38 | 38 | 38 | 43 |

Dimensional Tolerances of Welding Neck Flanges ASME B16.5
| Outside Diameter ≤ 24 = 1.6 mm | > 24 = ± 3.2 mm |
Inside Diameter ≤ 10 = ± 0.8 mm | 12 thru 18 = 1.6 mm | ≥ 20 = + 3.2 mm / – 1.6 mm |
| Diameter of Contact Face 1.6 mm Raised Face = ± 0.8 mm 6.35 mm Raised Face, Tongue & Groove / Male-Female = ± 0.4 mm |
Diameter of Hub at Base ≤ 24 = 1.6 mm | > 24 = ± 3.2 mm |
| Diameter of Hub at Point of Welding ≤ 5 = + 2.4 mm / – 0.8 mm | ≥ 6 = + 4.0 mm / – 0.8 mm |
Drilling Bolt Circle = 1.6 mm | Bolt Hole Spacing = ± 0.8 mm Eccentricity of Bolt Circle with Respect to Facing ≤ 2½ = 0.8 mm max. | ≥ 3 = 1.6 mm max |
| Thickness ≤ 18 = + 3.2 mm / – 0 | ≥ 20 = + 4.8 mm / – 0 |
Length thru Hub ≤ 10 = 1.6 mm | ≥ 12 = ± 3.2 mm |
Notes:
1. Dimensions are in millimeters unless otherwise indicated.
2. T = Nominal wall thickness of pipe. Bevel for Wall Thicknesses T from 5 mm to 22 mm inclusive.
3. The length of the stud bolt does not include the height of the chamfers (points).
