What is ANSI class 150 flange?

The American National Standards Institute (ANSI) Class 150 is a system of dimensional standards for weld neck, threaded, slip-on, lap joint, socket weld and blind flanges. Dimensions for facing, bolts and studs are also included in ANSI Class 150. Video of the Day.

How do you calculate the weight of a flange?

How to calculate the weight of pipe flanges?

1. Pipe flanges are used to connect pipe sections to other pipe sections, inline components, and equipment.
2. 1.The materials used to construct a pipe flanges directly relate to the weight and the pressure it can handle.
3. Pipe flanges volume=π/4*A1*A1－B1*B1－D1*C1*C1)*C(mm)

### What is the thickness of class 150 flange?

ANSI/ASME B16. 5 Class 150 Forged Flanges Add Flanges

Nominal Size Outside Diameter (OD) Min. Thickness (T)
1 4.25 0.50
11⁄4 4.62 0.56
11⁄2 5.00 0.62
2 6.00 0.69

What is a 150 flange?

As temperature increases, the pressure rating of the flange decreases. For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F.

How much does a 30 inch flange weight?

Series A 150 Blind Flange

28 36.5 345
30 38.75 400
32 41.75 505

## What does a 150 lb flange mean?

How do you calculate the weight of a wide flange beam?

Wide flange beams are designated by the letter W followed by the nminal depth in inches and the weight in pounds per foot. Thus W12 × 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot.

How many bolt holes in a 150 flange?

Diameters and bolt circles for standard ASME B16. 5 flanges – 1/4 to 24 inches – Class 150 to 2500.

Nominal Pipe Size NPS (inches) Class 150
Diameter of Flange (inches) Diameter of Bolt Holes (inches)
8 13-1/2 0.88
10 16 1
12 19 1

### Why is called a 150 flange?

If we consider a pressure rating of 150, it means that the safe working pressure for this pipe flange or valve at a specific temperature for a given material is 150 pounds per square inch.

What does a 30 blind flange weigh?

What is difference between Series A and B flanges?

Series A flange is heavier, thicker and cost more whereas series B flange has more bolt holes and is lighter cheaper than series A. API605 flange and series B flanges are same thing.

## What is ANSI flange standard?

ANSI B16. 5 -1996 is the official standard for ANSI Class Pipe Flanges and Flanged Fittings, applied specifically to those made from cast or forged materials, as well as blind flanges and some reducing flanges crafted in cast, forged, or plate.

What is ANSI class rating?

What is an ANSI Class Rating? The ANSI Class rating of a flange is defined as the maximum amount of pressure that the flange can withstand at increasing temperatures. There are seven primary pressure classes for flanges. They are 150, 300, 400, 600, 900, 1500, and 2500.

How do I know what class my flange is?

The Pressure Rating for flanges will be given in Classes. Class, followed by a dimensionless number, is the designation for pressure-temperature ratings as follows.. Class 150 300 400 600 900 1500 2500. Different names are used to indicate a Pressure Class.

### How is flange torque calculated?

Using a calibrated torque wrench (Manual or Hydraulic Torque Wrench), flange bolt torque can be measured during flange assembly….Applied Torque, T= (k∙f∙d)/12 in FPS Unit

1. T=Torque in ft-lb.
2. k=Dimensionless nut factor or tightening factor.
3. f=axial force in pounds.
4. d=Nominal bolt diameter in inches.
