split flange clamps are interconnected between the tube and pipe parts for connection between the pipe ends; equipment import and export is also useful in the flange for connection between the two devices. Pipe flange means the plumbing fixtures in the piping  hydraulic hose couplings , with import and export flange on the device means the device. There are holes on the flange bolts so that the two flanges tightly connected. Between the flange sealing gasket. Flanges are used in pairs, you can use the wire pick low-pressure pipe flange, gasket between the two pieces together with flanges, and then bolted. Flange thickness of the different different pressures, they use different bolts. Flanged easy to use, able to withstand greater pressure. In industrial pipe using  threaded adaptorsconnection is very extensive. Within the family, the pipe diameter is small, but low pressure, invisible flange connection. Flange by corrosion, impact erosion, temperature, pressure, vibration and other factors, there will inevitably leak. Since the flange has a good overall performance, so it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire protection, electrical, aerospace, shipbuilding and other infrastructure projects.
