EN1092-1 Flanges: The basis of industrial piping systems

 

Flanges are essential components in various industries, from chemical and petrochemical sectors to food and beverage industries.

They are used to connect pipelines, valves, tanks, and other equipment. DIN-EN1092-1 is a European standard that provides specific guidelines for flanges, focusing on dimensions, materials, and performance criteria. In this article, we will specifically delve into the dimensions of DIN-EN1092-1 flanges

The flanges according to the EN1092-1 standard form the basis of almost every industrial piping system in Europe, and even beyond. This standard has been specially developed for flange connections in piping systems that must be secure but also be able to withstand higher pressures and temperatures.

 

EN1092-1 are available in all kinds of different metals, but the most commonly used are steel and stainless steel.

 

Based on diameters and pressure classes

 

The EN1092-1 standards are based on both nominal diameters and pressure classes, each of which plays a crucial role in defining the specifications of flange connections.

 

A nominal diameter refers to the designated size of a flange, pipe, or fitting, typically expressed in millimeters.

 

A pressure class indicates the maximum pressure that a flange connection can safely withstand under specific operating conditions without failure. These pressure classes are denoted by numerical values such as PN6, PN10, PN16, and so forth. A higher pressure class signifies a greater pressure resistance of the flange connection.

 

This facilitates compatibility and interchangeability within a given system. For instance, a flange with a nominal diameter of 50 mm (DN50) and a nominal pressure class of 16 (PN16) will fit with pipes or fittings that also have a nominal diameter DN50 and pressure class PN16.

 

About flange dimensions

 

One of the key aspects of DIN-EN1092-1 flanges is dimensional consistency. This includes the flange diameter, thickness, bolt circle, and bolt hole diameter. These dimensions are precisely specified to ensure that flanges fit correctly and form a leak-free connection when assembled.

The flange diameter is a critical dimension, as it must match the diameter of the pipe to which the flange is being attached. Oversized or undersized diameters can lead to improper fits and leakages. Therefore, flanges are classified based on their nominal diameter, ranging from DN10 to DN4000, where DN stands for 'Diameter Nominal'.

In addition to diameter, the thickness of the flange is an important factor for structural integrity and performance under pressure. DIN-EN1092-1 specifies the minimum thickness of flanges for different pressure ratings to ensure they can withstand the forces exerted during operation. Too thin flanges may deform or collapse under pressure, while too thick flanges may result in excessive material usage without additional benefits.

The bolt circle, also known as the bolt circle diameter, determines the positioning of the bolt holes on the flange. This dimension is crucial as it allows for proper positioning of bolts and nuts to securely tighten the flange and ensure a leak-free connection. A uniformly distributed bolt circle ensures even loading of the flange and minimizes the risk of deformation or damage.

The bolt hole diameter is also standardized according to DIN-EN1092-1, with different sizes for bolts of different diameters. This ensures that the correct size bolts are used for each flange and that they can be securely tightened without the risk of breakage or excessive loading.
