 A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange).
The main use of flange is to connect pumps, pipes, valves, and other equipment to make a pipework system. Usually, flanges are threaded or welded, and you can connect two flanges by bolting them with gaskets and providing a seal that gives easy access to the piping system.

EN 1092-1 is a European standard that specifies the requirements for flanges used in piping systems. This standard covers a range of flange types, materials, and dimensions suitable for various applications. Here's a comprehensive overview of EN 1092-1:
EN 1092-1 OverviewEN 1092-1 is titled "Flanges and their joints - Flanges - Part 1: Steel flanges" and is commonly used for steel flanges. The standard specifies the dimensions, pressure-temperature ratings, materials, and other key characteristics of flanges.
Types of Flanges CoveredEN 1092-1 includes several types of flanges:
Weld Neck Flanges (WN)
Designed to be welded to the pipe.Provides a smooth transition between the pipe and the flange, minimizing stress concentrations.Slip-On Flanges (SO)
Slip over the pipe and are welded both inside and outside.Typically used for lower pressure and temperature applications.Blind Flanges (BL)
Used to close the end of a pipe or a valve.Provides a seal to contain pressure within the system.Threaded Flanges (TH)
Have internal threads that match the external threads of the pipe.Used where welding is not feasible.Socket Weld Flanges (SW)
The pipe is inserted into the flange and then welded around the socket.Suitable for high-pressure applications.Pressure-Temperature RatingsFlanges are classified according to their pressure-temperature ratings, which are designated by pressure classes. Common pressure classes in EN 1092-1 include:
PN 6PN 10PN 16PN 25PN 40PN 63PN 100PN 160Each class specifies the maximum pressure the flange can handle at a given temperature.
DimensionsEN 1092-1 defines detailed dimensions for each flange type and size. Key dimensions include:
Nominal Diameter (DN): The flange size, typically ranging from DN 10 (1/2 inch) to DN 600 (24 inches) and beyond.Bolt Circle Diameter (BCD): The diameter of the circle that the bolt holes are drilled into.Number of Bolts: The number of bolt holes varies by size and pressure class.Bolt Hole Diameter: The diameter of the holes for bolts.Flange Thickness: The thickness of the flange varies by size and pressure class.Raised Face (RF): The height of the raised face, if applicable.Material SpecificationsEN 1092-1 specifies several materials for flanges, including:
Carbon Steel: EN 10216-2, EN 10210Stainless Steel: EN 10088-1, EN 10088-2Alloy Steel: EN 10216-5Ductile Iron: EN 1563Flange Face TypesEN 1092-1 specifies different flange face types:
Raised Face (RF)Flat Face (FF)Ring-Type Joint (RTJ)Each type has different characteristics and is suitable for various applications.
Flange Designations and ExamplesEN 1092-1 designates flanges with a combination of nominal diameter, pressure class, and type. For example:
DN 50 PN 16 SO: Slip-On Flange with a nominal diameter of 50 mm and pressure class PN 16.DN 100 PN 40 BL: Blind Flange with a nominal diameter of 100 mm and pressure class PN 40.Equivalent Standards and ReferencesEN 1092-1 is widely used in Europe and has some equivalent standards internationally:

Flanges are used to restrain pipeline movement caused by thermal expansion changes or external forces. The most common method of securing an anchor flange is to embed it into a concrete thrust block, thereby spreading the pipeline forces throughout a large foundation. However, anchor flanges can be secured in other ways as necessary to overcome the axial force in the pipeline.

Pressure RatingsSpectacle blinds are rated according to pressure classes that reflect their ability to withstand various internal pressures. Common pressure classes include:• Class 150: Suitable for low-pressure applications.• Class 300: Medium pressure applications.• Class 600: High-pressure applications.• Class 900: Very high-pressure applications.• Class 1500: Extremely high-pressure applications.• Class 2500: Ultra-high-pressure applications.5. Standards• ASME B16.5/B16.48 Provides dimensions, materials, and pressure-temperature ratings for flanges and fittings.• MSS SP-44: Specification for spectacle blinds and other pipe fittings, including detailed dimensions and pressure ratings.SPECFICATIONS:• Manufacturing Range: DN 15 (1/2”) to DN 1500 (60”)• Rating/Class: 150/300/600/900/1500/2500 and SCH 5/5S/10/10S/20/40/STD/60/80/XS/100/120/140/160/XXS etc.• Dimension Standard: ANSI/ASME B16.48/B16.5, etc.Material Type: HIGH NICKEL ALLOYS: Inconel 600, Inconel 625, Inconel 718, Inconel 800, Inconel 825, Monel 400, Monel K-500, Hastelloy C-276, Hastelloy B-2, Hastelloy C-22, Titanium Gr 2, Titanium Gr 5CARBON/ALLOY STEEL: ASTM/ASME A105/105N, ASTM / ASME A182, ASTM / ASME A335 GR F1, F5, F9, F11, F12, F22, F23, F91, ASTM A516 GR 60/70, ASTM A516 GR 60, ASTM A516 GR 70LTCS: ASTM/ASME A350 LF2, ASME/ASTM A694 F42, F46, F52, F60, F65, F70STAINLESS STEEL: ASTM A182 F304 (1.4301), F304L (1.4306/1.4307), F316 (1.4401), F316L (1.4404), F304H, F309S, F309H, F310S, F310H, F316TI, F316H, F316LN, F317, F317L, F321, F321H, F11, F22, F91, F347, F347H, F904L,  UNS S 31254 (1.4547) DUPLEX STEEL: Duplex (S32205 / S31803) X2CrNiMoN22-5-3 (1.4462), S32750 (EN/DIN 1.4410, X2CrNiMoN25-7-4), S32760 (1.4501, X2CrNiMoCuWN 25-7-4)HIGH NICKEL ALLOYS: Inconel 600, Inconel 625, Inconel 718, Inconel 800, Inconel 825, Monel 400, Monel K-500, Hastelloy C-276, Hastelloy B-2, Hastelloy C-22, Titanium Gr 2, Titanium Gr 5COPPER NICKEL ALLOYS: CUNI 90/10 (C70600), CUNI 70/30 (C71500)
