DIN Flange

DIN FLANGENormally, in industrial applications, flanges are in various shapes and sizes and can be made of a variety of materials. However, the type of material used in the flange has nothing to do with the flange type or size. The flanges produced under the standard requirements set by the German Standardization Association (DIN) are called DIN, divided into DIN2631, DIN2632, DIN2633, DIN2634, DIN2635, DIN2576, DIN2502, DIN2566, DIN 86029, DIN86030, DIN2527.

DIN Flange VS ANSI Flange

1. Material (Similarity):

The flanges (DIN standard and ANSI standard) is made of carbon steel, stainless steel as well as alloy steel.

2. Design Pressure (Difference):

The DIN flanges prssure is PN2.5/PN6/PN10/PN16/PN25/PN40

The ANSI flanges pressure is 150LBS/300LBS/400LBS/600LBS/900LBS

3. Type (Difference):

Plate(DIN2573 2576 2502)

Blind(DIN2527)

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):

DIN standard flange is connected with DIN pipeline products, and ANSI flange is used in American standard piping systems,

They are all connected by bolts.

DIN Flange FAQs

Q What Are the Main Features of Flange Connection?
A.

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 Flanges?
A.

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 the Warranty Time for Flanges?
A.

Generally, our warranty time for flanges is 12 months
