How do you calculate the weight of a flange?
How to calculate the weight of pipe flanges?
- Pipe flanges are used to connect pipe sections to other pipe sections, inline components, and equipment.
- 1.The materials used to construct a pipe flanges directly relate to the weight and the pressure it can handle.
- Pipe flanges volume=π/4*A1*A1－B1*B1－D1*C1*C1)*C(mm)
What is class 125 flange?
In terms of drilling and flange O.D. 125 class is the same as 150 class and 250 class if the same as 300 class. 1 Class 125 flange is rated for 125 psi at 353ºF (178ºC), which is the boiling temperature for water at that pressure. As temperature increases, the pressure rating of the flange decreases.
How much does a 12 inch flange weight?

How do you calculate the weight of a weld neck flange?
According to ASME B16. 5, the straight length is furnished in 10 mm. Hence the weight of Part I can be calculated by using the weight-calculation formula of pipe: W1 = 0.0246615 * (A – Tk) * Tk * 0.01 Tk – wall thickness of the mating pipe.
How do you measure flange thickness?
The blind flange is attached by bolts causing an edge moment (Fig. UG- 34. /sketch j) in which the thickness can be calculated by : t = d *(CP/SE+1.9W hg/SE*d^3) ½ ……………….
What is the difference between a 125 flange and a 150 flange?
Class 125 and Class 250 are cast iron flanges and flanged fittings while Class 150 and Class 300 are ductile iron, steel or stainless steel. 42 Class 150 is made from ductile iron. However, the bolting pattern is the same for both Class 125 and 150 so, regardless of material, they will bolt together.
What is 150 class flange?
Flanges can withstand different pressures at different temperatures. 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.

What is blind flange?
It is used to terminate the end of a piping system. The blind flange is basically a flange that does not have a hub or a bored center. Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern. Blind flanges can also be used to seal a nozzle opening on a pressure vessel.

Which is AWWA flange rated at 125 psi?
Posted in Ductile Iron Flange Datasheets The flanges of AWWA C110/A21.10 and AWWA C153/A21.53 standards conform to the drilling and facing of ASME B16.1 Class 125 flanges. This ASME B16.1 Class 125 designation leads some to conclude that these AWWA flanges are only rated at 125 psi service which is not correct.
