Shijiazhuang, pipe manufacturers | Hebei pipe factory flange (flange, joint) by a pair of flanges, a gasket, and composed of a number of bolts and nuts. Gasket on the sealing surface between the two flanges, tighten the nut, the gasket surface pressure reaches a certain value deformation, Shijiazhuang, pipe manufacturers | Hebei fill the sealing surface of the Factory and rugged place, the connection does not leak tight. Detachable flange connection is a connection. Shijiazhuang, pipe manufacturers | Hebei pipe factory parts connected by the flange and the container can be divided into law; by structural type of points, there are a whole flange, loose flanges and threaded flange. Common integral flange with welded flange and the welded flange. Shijiazhuang, pipe manufacturers | Pipe Factory, Hebei's less rigid welded flange for pressure p ≤ 4MPa occasions; welded neck flange flange also known as high, rigid large, high pressure and temperature for the occasion . Flange sealing surface, there are three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, for higher pressure of the occasion; tongue and groove sealing surface, for flammable, explosive , toxic medium and high pressure situations.
Shijiazhuang, pipe manufacturers | Hebei support flange welded pipe factory
Gasket is to produce plastic deformation, and material with a certain intensity of the ring. Most pads are cut off from the metal plate, or by professional Shijiazhuang, pipe manufacturers | Hebei making required size of the Factory, Shijiazhuang, pipe manufacturers | Hebei pipe factory material for asbestos rubber sheet, asbestos, PE board; also useful for sheet metal (tin, stainless steel) will be non-metallic materials such as asbestos wrapped Qilai gasket made of metal packages; Shijiazhuang, pipe fittings manufacturers | Hebei pipe factory there is a thin strip along with the asbestos tape around the system from the spiral wound gasket. Ordinary rubber gasket temperature lower than 120 ℃ for the occasion; asbestos rubber gasket suitable for water vapor temperature below 450 ℃, on the oil temperature is below 350 ℃, the pressure is lower than 5MPa occasions, Shijiazhuang, pipe manufacturers | Pipe Factory, Hebei corrosive media in general, the most commonly used is the acid asbestos. In the high-pressure equipment and piping, copper, aluminum, 10 steel, stainless steel or other lens-type shape of the metal gasket. Shijiazhuang, pipe manufacturers | Hebei pipe factory gasket and sealing surface high-pressure contact width is very narrow (line contact), with the gasket sealing surface of the processing finish higher.
Low-voltage wire of small diameter flange, high pressure and low pressure are the use of large diameter welded flange, flanges of different thickness of the pressure and diameter and number of bolts is different.
