DIN 2527 Flange

DIN 2527 flange is a blind flange conforming to the German industrial standard DIN 2527. Its primary function is to seal the end of a piping system or to temporarily close off a pipeline that is not in use.

High Quality DIN 2527 Flange

Pressure Ratings:DIN 2527 flanges are commonly available in the following PN (Pressure Nominal) classes:

PN6, PN10, PN16, PN25, PN40

Size Range: DIN 2527 flanges are based on the nominal diameter (DN) of the pipeline, with typical size ranges including:

From DN15 (or smaller) up to DN600

Common Materials for DIN 2527 Blind Flanges (EN Standards)

Material Type	Material Name	EN Material No.	Standard(s)	Equivalent (if any)	Notes
Carbon Steel	P250GH	1.046	EN 10222-2 / EN 10028-2	—	Common pressure vessel steel for high temp/pressure
	S235JR	1.0038	EN 10025-2	—	Low strength structural steel for ambient conditions
	S355JR / S355J2	1.0045 / 1.0577	EN 10025-2	—	Higher strength structural steel for large diameters
Stainless Steel	X5CrNi18-10	1.4301	EN 10088-1	AISI 304	Common austenitic stainless steel, good corrosion resistance
	X2CrNi18-9	1.4307	EN 10088-1	AISI 304L	Low-carbon version of 304, ideal for welding
	X5CrNiMo17-12-2	1.4401	EN 10088-1	AISI 316	Mo-alloyed, better corrosion resistance
	X2CrNiMo17-12-2	1.4404	EN 10088-1	AISI 316L	Low-carbon 316, excellent for welded piping systems

Typical Applications

Comparison: DIN 2527 vs. DIN EN 1092-1 Type 05

Item	DIN 2527	DIN EN 1092-1 Type 05
Type	Blind flange	Blind flange
Replacement Status	Replaced by EN 1092-1 Type 05	More widely used in modern applications
Scope of Application	German national standard	European standard with broader international acceptance
Dimensions, Bolt Circle, Thickness	Largely identical across most PN ratings	Also covers PN6–PN40, consistent with DIN 2527

FAQ

Is DIN 2527 still in use?

Yes, especially in traditional and German-based engineering systems. However, in the EU, DIN EN 1092-1 Type 05 is becoming the preferred standard.

What is the difference between DIN 2527 and DIN EN 1092-1 Type 05?

Control welding heat input, ensure rapid post-wBoth refer to blind flanges, but EN 1092-1 Type 05 is a European standard replacing older DIN standards. They are mostly compatible in terms of dimensions and use.eld cooling, and avoid 600–900°C temperature range.

Do DIN 2527 flanges require gaskets?

Yes, for most pressure applications, a gasket is required between the flange face and mating surface to ensure a proper seal.

Can DIN 2527 flanges be used with ANSI or JIS flanges?

No, unless specifically adapted. DIN flanges follow metric dimensions, while ANSI and JIS follow imperial or Japanese standards. Mismatched flanges can lead to sealing or bolt alignment issues.

As a standardized product, DIN 2527 flanges are designed with a focus on sealing performance, installation reliability, and mechanical strength, making them widely used in industrial piping systems.

Note: With the adoption of European standards such as DIN EN 1092-1, DIN 2527 has gradually been replaced in some applications, but it is still widely used in traditional and specific industrial sectors.
