What is a Series B flange?

What is a Series B flange?

Series B flange was also formerly known as API 605 flange. Term B16. 47 or B 16 47 or ANSI B 16 47 are all used interchangeabily and refers to the same standard. ASME B16. 47(Large Diameter Steel Flanges) is a standard for large diameter steel pipe flanges sized from NPS 26 through NPS 60.

What does class 150 pipe mean?

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. In other words, when the pressure goes down, the temperature goes up and vice versa.

What does PN mean in flanges?

Flange Pressure Nominal
Pressure numbers (PN) vs. flange class designations.

Flange Class	150	400
Flange Pressure Nominal (PN)	20	68

What is the difference between 16.47 Series A and B?

ASME B 16.47 standard has two series such as Series A and Series B flanges. The difference between these flanges are: Characteristics: ASME B16 47 Series A flanges are much heavier, thicker, and more robust than Series B flanges with the same pressure rating and size.

What are the different flange standards?

The key types of flanges are the welding neck, long welding neck, slip-on, socket weld, lap joint, threaded and blind flanges. In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges.

What does PN stand for in pipes?

Notes: PN Is the nominal working pressure rating. The number used to describe PN is 10 times the value of the maximum allowable operating pressure (MAOP) at 20°C (MPa x10) based on a design factor of 1.25. SDR Nominal ratio of outside diameter to wall thickness.

What does PN and DN mean?

Nominal diameter (DN) and nominal pressure (PN)

What does pn6 mean?

PE pipes are produced in different pressure grades (PN grades), which indicates the pressure in bars the pipe can support with water at 20 oC. The pressure grades available according to European standards are. PN 2.5 – max pressure 2.5 bar. PN 4 – max pressure 4 bar. PN 6 – max pressure 6 bar.

What does B16 mean on a flange?

ASME B16.20. Metallic Gaskets for Pipe Flanges. This Standard covers materials, dimensions, tolerances, and markings for metal ring-joint gaskets, spiral-wound metal gaskets, metal-jacketed gaskets, and grooved metal gaskets with covering layers.

What are the two main types of flanges?
