Flanges Manufacturers

Also known as the flange or flange. The tube and pipe parts connected to each other. Connected to the pipe end. There are perforations can be worn bolts, so that the two flange abuts the flange. Between flange sealing gasket. Flange pipe fittings (flanged pipe fittings) refers tube with a flange (flange or disk access) is. It can be cast from (Figure Reserved), but also by screwing or welding composition. Flange connection (flange, joint) by a pair of flanges, a gasket and a number of bolts and nuts. Spacer placed between the two flange sealing surface, tighten the nut, the pressure over the gasket surface deformation reaches a certain value, and fill the sealing surface uneven, the coupling does not leak tight. Flange connection is a detachable connection. According to the connected components can be divided into the container flange and pipe flange. By structure type, with integral flanges, loose flanges and threaded flange. Common integral flange having welded flange and welded flange. Less rigid flat welding flange, for pressure p≤4MPa occasions; also known as high-neck flange welded flange, greater rigidity, suitable for high pressure and temperature applications. Type flange sealing surface in three ways: planar sealing surface, the pressure is not suitable for high, medium nontoxic occasions; uneven sealing surface for higher pressure situations; tongue and groove sealing surface, for flammable, explosive toxic medium and high pressure applications. A gasket is capable of plastic deformation, and has a certain strength of the ring material. Most pads are cut down from the metal sheet, or by a professional factory according sized, the material is asbestos rubber sheet, asbestos, polyethylene board; it also uses a thin metal plate (white metal, stainless steel) asbestos other non-metallic materials wrapped up clad gasket made; there is a band along winding spiral wound gasket made of thin steel and asbestos. Ordinary rubber gaskets for temperature lower than 120 ℃ of occasions; asbestos rubber gasket is suitable for steam temperature is below 450 ℃, for the oil temperature is below 350 ℃, the pressure is lower than 5MPa occasions, for general corrosion medium, most commonly used is the acid asbestos. In the high-pressure equipment and piping, copper, aluminum, steel No. 10, the lens type or other shapes metal gasket made of stainless steel. Contact width of the sealing surface high pressure washer is very narrow (line contact), the gasket sealing surface and high finish machining. Flange threaded connection points (wire tapping) flange and welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange thickness and bolt diameter and the number of different connection flange pressures are different.
