The pipe and pipe interconnected parts, connected to the pipe end. There are holes on the flange, so that the two flange bolts tight. The flange gasket seal. Flanged fittings (flanged pipe fittings) refers to a flange pipe. It can be formed by casting and (figure not available), may also be threaded or welded. Flange connection (flange, joint) consists of a pair of flanges, a gasket and a plurality of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. Removable flange connection is a connection.
By the connected components can be divided into the container flange and pipe flange. According to the structure type, with integral flanges, flange and threaded flange. Integral flange are common flange and butt welding flange. Less rigid flange, suitable for pressure P ≤ 4MPa occasion; welding neck flange also called Orifice Weld Neck Flanges large rigidity, suitable for high temperature applications. Flange sealing surface of three types: planar sealing surface, suitable for pressure is not high, medium non-toxic occasions; uneven sealing surface, the pressure is slightly higher for the occasion; tongue and groove sealing surface, suitable for flammable, explosive, toxic medium and high pressure situations.
Gasket is to produce plastic deformation, and the materials with certain intensity ring. Most of the metal plate gasket is not cut down, or by professional plant size, the material is asbestos rubber sheet, asbestos board, polyethylene plate; also useful for sheet metal (iron, stainless steel) of asbestos and other non-metallic materials wrapped made of metal jacketed gasket; and a belt.
Winding and asbestos tape made of thin steel into a spiral wound gasket. Ordinary rubber gaskets used in temperature below 120 ℃ occasions; asbestos rubber gasket is suitable for steam temperature is below 450 ℃, the oil temperature is below 350 ℃, the pressure is lower than the 5MPa of the occasion, for corrosive media in general, is the most commonly used acid-resisting asbestos board. In the high-pressure equipment and piping, metal gasket with lens type of copper, aluminum, steel 10, stainless steel or other shape.
High-pressure gasket and sealing surface of the contact width is very narrow (line contact machining finish), gasket sealing surface and the degree of. Sub-threaded flange connection (wire connected flange and welding flanges). Low voltage and small diameter wire connected flange, high pressure and low pressure are the use of large diameter welded flange, different pressure flange thickness and bolt diameter and the number is different.
