EN 1092-1 flanges are circular steel flanges that are used in piping systems. They are specified by their pressure class (PN), nominal size (DN), and flange type. The pressure class indicates the maximum pressure that the flange can withstand, and the nominal size indicates the inside diameter of the pipe that the flange is designed for. The flange type refers to the shape of the flange face and the method of attachment to the pipe. The EN 1092-1 standard specifies the following flange types: Type 01: Plate flange for welding Type 02: Loose plate flange with weld-on plate collar Type 03: Weld neck flange Type 04: Loose flange with weld-neck collar Type 05: Blind flange Type 21: Integral flange Type 31: Weld neck flange with raised face Type 32: Weld-on plate collar with raised face Type 33: Blind flange with raised face Type 34: Socket weld flange Type 35: Socket weld flange with raised face The EN 1092-1 standard also specifies the materials that can be used for EN 1092-1 flanges, the surface finish of the flange faces, and the tolerances for the dimensions of the flanges. Here are some of the key technical specifications of EN 1902-1 flanges: Nominal sizes: DN 10 to DN 4000 Pressure classes: PN 2.5 to PN 400 Materials: Carbon steel, stainless steel, ductile iron Facings: Raised face (RF), flat face (FF), ring joint (RJ), tongue and groove (TG) Dimensions and tolerances: Defined in EN 1902-1 Marking: Defined in EN 1902-1 EN 1092-1 flanges are used in a variety of applications, including water, gas, and oil pipelines, as well as in chemical and process industries. They are a reliable and versatile type of flange that can be used in a wide range of conditions.
We manufacture flanges in a variety of sizes and material standards. We have a large stock of carbon steel, alloy steel and stainless steel flanges. We can also manufacture your specific flange requirements within a short lead time. Changhao is a leading steel flanges exporter and manufacturer in China and we produce most of our carbon steel flanges and stainless steel flanges for export from China to the world. Steel flanges are available in a variety of shapes and sizes to suit different applications. Flanges are usually in the shape of a disc and are used to connect two pipes together or to connect pipes to pressure vessels, valves, pumps, integral flange assemblies or other components. Flanges have bolt holes around the rim. The bolts are used to connect two flanges, which are usually attached to the pipe end with a gasket in between. Flanges come in a variety of shapes, such as threaded (the pipe is screwed onto the flange), weld neck (the pipe is welded to the collar of the flange), socket weld (fillet weld connection), lap joint (connection at the short end used)), sliding, etc. The flange can also be used to cover or close the plate at the end of the pipe. This is called a blind flange. Therefore, flanges are considered to be internal components used to support mechanical parts. The ASME B16.5 and ASME B16.47 codes cover American standard pipe flanges and the EN 1092-1 code covers European steel flanges. Flanges can be manufactured and designed for specific pressure ratings; 150 lb, 300 lb, 400 lb, 600 lb, 900 lb, 1500 lb and 2500 lb.

Long-necked flanges, also known as LWN flanges, are similar to the standard weld neck flanges but the neck is considerably longer. This type of flange is often used as a nozzle for a barrel or a column. They can be classified later as standard type, heavy gun type, variable body type and whole body type. These flanges are kind of exclusive for the reason of their uncomplicated connectivity with other pipes. Where standard weld neck flanges are used extensively for pipes, long weld neck flanges (often abbreviated to LWN) are used in high pressure and high (or fluctuating) temperature situations primarily in the oil and gas industry. The long neck guides the pipe into the flange itself and provides reinforcement that a standard weld neck flange cannot. This reinforcement is very important for safety in high pressure industrial, commercial and even residential systems. Uses of long-necked flanges are primarily on vessels where an elongated neck is required. Long-necked flanges (LWN) are primarily utilised on vessels where an elongated neck is required. This is considered a specialty flange because of the protruding neck or hub, which acts as a boring extension. The conical collar helps reduce the thickness of the steel and appears to be a pipe extension. LWN steel flanges are used primarily in the chemical and petroleum industries, as well as in commercial and residential buildings ASME 16.47 anf asme 16.5 series of long weld flanges are used exclusively for situations in high levels of stress and fluctuating temperatures.
