Outer Diameter (OD) : 32mm/50mm/63mm/90mm x 100m. Lightweight for ease of installation and handling.

DIN sets industry standards for quality assurance and safety, including flange materials requirements and pressure and temperature rating. While DIN flanges are less common in the United States, imported systems and equipment or international maritime vessels may require these metric pipe flanges and parts.

The DIN 2576 PN10 Flange helps inspect and checks, which allows smooth and efficient upkeep and efficient media flow. The Flanges Norma DIN 2576 PN10 is made up of heavy metals or alloys like carbon steel, stainless steel, etc., and it is available in different types which perform different functions accordingly.

The din 2635 flange dimensions can vary for material grades as well. The most used materials are the stainless steel. These flanges can be seen in general corrosive applications, high temperature pressure applications, marine applications, oil and gas applications and in other industrial applications as well.

Nominal Pressure (PN)

The PN rating is the maximum permitted operational pressure in bars calculated at 20°C, for example PN6 indicates a maximum working pressure of 6 bars.

This means that the flange is designed to withstand a maximum pressure of 100 bar at 20 degrees celsius temperature. Likewise, PN6, PN10, PN16, and PN25 will have the PN pressure rating is 6 bar, 10 bar, 16 bar, and 25 bar at 20-degree celsius respectively.

PN 6 gaskets are some of the most commonly used sizes of standard pipe gaskets. PN 6 gaskets can be manufactured either as IBC gaskets (sitting inside the bolt circle of the flange) or as full faced gaskets (with bolt holes) to cover the face of the flange.

For example, if the minimum value of C is chosen (C = 1.25), a PN 10 pipe will have a MAOP of 1.0 MPa at 20°C. PE pipe pressure ratings based on C=1.25 are given in the Table below.

DN stands for 'Diameter Nominal'. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm. We refer to a 12″ flange as DN300, when in fact it is 304mm.

The Difference Between ANSI and DIN

DIN is most commonly specified in European countries, while ANSI is usually specified in the United States. Therefore, the majority of factories in North America are likely to have piping that is ANSI certified, while similar plants in European countries have DIN piping.

'PN' stands for Pressure Nominale and prefixes the pressure rating, e.g. a PN16 flange is designed to operate up to 16 bar.

DIN 2501, is a standard which has become a part of the ISO 7005, following which the Flange EN 1092-1 RF was created as the standard for DIN based flanges. Generally the now obsolete, BS4504 flanges were same as the old DIN 2501 specification, but the new Lap Joint Flange En 1092 standard covers a wider range.

What do DN and PN mean on flanges? ›

Nominal diameter (DN) and nominal pressure (PN)

PN is the numerical naming of each piping component system based on its mechanical properties, which is used as reference value. The PN is the France term for the nominal pressure; the pressure instead of real pressure of a certain pipe. PN is usually used in the European standards DIN, EN, BS, ISO and so on.

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.

Slip-on bossed flanges are usually fillet welded to steel pipe or tube, these PN6 flanges are 6 bar pressure rated and have an operating temperature range of -10°C – 300°C.

PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric flange dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements.

PN6. 3 (SDR26) – Max rating of 63m of Head pressure = 630Kpa = 6.3 Bar = 92 psi.

The HDPE 50MM PN 6 HDPE PIPE material is critical to the overall success of the ground source geothermal system. It must provide corrosion resistance, chemical resistance, flexibility, impact resistance, resistance to slow crack growth, long-term hydrostatic strength (pressure capability), and temperature resistance.

Nominal pressure 16 bar; maximum internal allowable pressure (in bar) of a mechanical component, considering a temperature of 20 °C.

Are PN10 and PN16 flanges the same? ›

Note: PN10/16 - Some flanges are denoted PN10/16. These refer to the fact that either PN10 or PN16 flanges will fit, as the drillings for many sizes are the same.

Maximum allowable working pressure (MAWP) is an American Society of Mechanical Engineers (ASME) designation that establishes the rating for pressure-relief components on vessels. It measures the greatest amount of pressure that the weakest part of the vessel can handle at specific operating temperatures.

What is a PN10 pipe? It's pipe's pressure rating terminology, generally used for CPVC, UPC , HDPE etc. made pipes. Here PN is an abbreviation meaning “Pressure nominal” meaning the maximum pressure the pipe can bear in bar. So PN10 signifies that pipe can sustain pressure upto 10 bar.

Universal Gasket for Flange DN250 - PN10 - Thickness: 2mm - Max 150°C.

PN ratings do not provide a proportional relationship between different PN numbers, whereas class numbers do. Class numbers are therefore recommended before PN ratings. Note! The piping rating must follow the pressure-temperature rating of the weakest pressure containing item in the system.

What Do DN and NPS Stand For? DN stands for diametre nominal, which denotes the size of a pipe (specifically, its inside diameter) in millimeters (mm). NPS, or nominal pipe size, is merely the non-metric equivalent in which the diameter is measured in inches (in.).

DIN standards provide companies a basis for quality, safety and minimum functionality expectations and enable you to: Minimize risk. Improve marketability.

STANDARDS - ISO / BS / DIN

With reference to fasteners, DIN number indicates the that the part conforms to a specific metric standard. The International Standards Organisation (ISO) standard has evolved to supersede the DIN standard, which was historically the predominant metric fastener system referred to.

A standard automobile radio body size. A DIN radio (single DIN) measures 2x7", while a double DIN measures 4x7". When factory radio/CD players are replaced with aftermarket units, the DIN standard ensures compatibility; however, new or altered dashboard trim may be required.

How to select the right flange rating? The term “flange rating” (or class) refers to the maximum pressure (in psi or bars) that a flange withstands at increasing temperatures. Flanges with a higher rating (class) are stronger than flanges with lower ratings, as they bear more pressure at increasing temperatures.

How do you read a flange class? ›

The flange rating or class refers to the maximum pressure that a flange withstands at the increasing temperatures. Flanges with a higher rating are stronger than the flanges with a lower rating, which means 600# flanges can bear more pressure than 150# flanges.

The most common flange types are: Welding Neck Flange. Slip-on Flange. Socket Weld Flange.

1) ANSI/ASTM specifies socket sizing in millimeters as well as fractions of inches, while DIN uses only millimeters. 2) ANSI/ASTM and DIN Socket standard show different diameter sizes for an impact socket of a given hex size.

HDPE Pipe Pn10, Thickness: 110 mm.

Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on the tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.

Nominal thickness is “in name only” used solely for identification. The nominal size may not match any dimension of the product, but within the domain of that product. The nominal size may correspond to a large number of highly standardized dimensions and tolerances.

PN rating. The acronym PN stands for Pressure nominal. When a pipe has a rating of PN16, it is designed to handle an internal pressure of 16 Bar.

nominal pressure (PN) : A numerical designation relating to pressure that is a convenient round number for reference purposes. It is intended that all equipment of the same nominal size (DN) designated by the same PN number shall have the same mating dimensions appropriate to the type of end connections.
