从India供应商批发进口En 1092-1 Flanges — FOB条款

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.
