Different Types of Forged Steel Flange
Forged steel flanges are widely used when two machinery parts need to be connected together, they are frequently used in different systems including pumps, valves, pipes to make the structure and object stronger. There are 7 common types of flanges, threaded flanges, socket weld flanges, lap Joint flanges, slip on flanges, blind flanges, weld neck flanges, spectacle flanges. And basing on the pressure rating, there are class 150, class 300, class 6000, class 9000, class 1500, and class 2500. Now you know what is a class 150 threaded flange.
Dimensions and Weight of Class 150 Threaded Flange
You can calculate the estimated volume and weight through the below class 150 treaded flange dimension and weight chart. Please notice the material and weight is not inlcude the stud bolts used with the flange, they must be ordered individually.

Material Types of Class 150 Threaded Flanges
Commonly used materials all can be applied in manufacturing of all flanges, they can be divided into below four different types. They may have different name in different county standard, but you can specify them through their chemical composition and mechanical property
Standard | ASME B16.5, EN1092-1 |
Carbon Steel | ASTM A105 / A105N |
Low Temp Carbon Steel | ASTM A350 LF2/LF3 |
Pipeline Steel | ASTM A694 F42 / 46 / 56 / 60 / 65 |
Alloy Steel | ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 |
Package of Forged Steel Flange
For size below 8 inches, there will be a plastic protector for each flange and all flanges packed in a wooden case with water prof.
Size between 8 inches and 12 inches, they are wooden pallet with protector.
Size over 12 inches is nude.
