Industrial Flange A flange is a rib for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc. Pipes or tubes can be easily assembled or disassembled by using it. In addition to pipes, flanges are fit to many other components such as bellows, wheels and cameras. Depending on different designs, flanges contain weld neck flange, slip on weld flange, threaded flange, socket weld flange, orifice flange, blind flange, and more. Classified by raw material, the flange we can offer includes carbon steel flange, alloy steel flange, stainless steel flange, high yield steel flange (Line pipe flange), low-temperature steel flange, etc. To allow easy interchangeability, flange faces are made to standardized dimensions, typically are Flat Face (FF), Raised Face (RF), Tongue (T), Groove (G), Female (F), Male (M), Ring Joint (RJ). Yingke industrial flanges are used extensively in pipe fittings of all kinds of industrial, commercial and residential applications. Some of the industries they serve include petroleum, natural gas, chemical, shipbuilding, papermaking, and metallurgy etc. Our industrial flanges can be fabricated by a variety of materials, including: Carbon Steel: ASTM/ASME A105, ASTM/ASME A516 Grade 55-60-65-70 Alloy Steel: ASTM/ASME A182 F1-F12-F11-F22-F5-F9-F91-F911-F92 Stainless Steel: ASTM/ASME A182 F304-F304H-F304L-F304N-F304LN F316-F316H-F316L-F316N-F316LN F321-F321H F347-F347H, ASTM/ASME A182 F51-F52-F53-F54-F55-F60-F61 Low-Temperature Steel: ASTM/ASME A522, ASTM/ASME A707 Grade L1-L2-L3-L4-L5-L6-L7-L8 High-Strength Steel: ASTM/ASME A694 F42-F46-F48-F50-F52-F56-F60-F65-F70 Yingke is a China industrial flange manufacturer and supplier.
