PN 10 Flange

The PN10 flange approximation is understood as flange disks with a pressure resistance of 1.0Mpa. Nominal pressure PN is a numeric pressure-related marker code, a convenient round integer for reference. All pipe accessories of the same nominal common diameter represented by the same nominal pressure PN value have the same connection size adapted to the end connection type.

PN 10 Flange VS ANSI 150 Flange

1. Material (Similarity):

The flanges (PN10 and ANSI 150) are made of carbon steel, stainless steel as well as alloy steel.

2. Design Pressure (Difference):

The PN10 flanges pressure is 10kgs

The ANSI 150 flanges pressure is higher than PN10 flanges.

3. Type (Difference):

Plate(DIN2573 2576 2502)


Loose(DIN 2673 2674 2675 2676 2641 2642 2655 2656)

Weld Neck(DIN2627 2628 2629 2630 2631 2632 2633 2634 2635 2636 2637 2638)

Threaded(DIN2565 2566 2567)

Slip On(DIN86029 86030)

4. Installation (Similarity and Difference):

PN10 flanges are used in DIN/BS/UNI standard piping systems and 150 lb flanges are used in ASME/ANSI standard piping systems.

Although they are both flanges, their connection data are different and cannot be interchangeable. 

PN 10 Flange FAQs

Q What Are the Main Features of PN10 Flanges Connection?

The main features of flange connection are easy disassembly, high strength, and good sealing performance. During the installing, the two flanges are required to be parallel, the sealing surface of the flange should not be damaged and it should be cleaned. 

Q How to Inquiry PN10 Flanges?

It is best to describe as specific as you can. Details about flanges are including type(SO, WN, TH, BL, SW, LP, etc.), material, pressure, facing( RF, FF, RTJ, etc.), standard, and quantity, for example, 2” ASTM A105 SO flange, Class 150, RF, ANSI B16.5.

Q How Long is Lead Time for One PN10 Flange Order?

Generally, the lead time is about one month. If you have a deadline, please let us know in advance and we will try our best to fulfill your order in time.
