Forged steel flange is based on the invention into production, and its intensity is higher than a lot of steel flange
So that the tube and pipe parts connected to each other, connected to pipe end. There are hole forged flange, flange bolt abuts the two. Between the use of forged flange sealing gasket. Forged flange pipe (flanged pipe fittings) with a forged flange means (or access plate nosing) of the tube. It may be cast by (Figure N), can also be threaded or welded connections pose. Connection flange (flange, joint) by a flange, a gasket and nut composed of a number of bolts. On the flange gasket sealing surface between the two, fastening nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the leakage is not so closely linked. Detachable flange connection is a connection. Connected components by the container can be divided into the flange and pipe flange. In accordance with sub-structure, there are a whole flange, live sets and threaded flange flange. Common overall flange are flat flange and butt welding flange welding. Flat welding flange forged less rigid, the pressure applied to the p ≤ 4MPa occasions; welded neck flange flange, also known as high, more rigid, higher temperature for the pressure to do so.
Forged flange sealing surface of the type there are three: planar sealing surface for the pressure is not high, medium non-toxic occasions; convex sealing surface for a slightly higher pressure occasions; mortise groove sealing surface, apply to flammable, explosive, toxic medium and high pressure occasions. Gasket is a plastic deformation can produce and has a certain intensity of the ring material. The majority of non-metallic gaskets from the Conference board down, or by professional plant size in accordance with the regulations, the material for the asbestos-rubber board,, polyethylene, etc.; also useful for sheet metal (white metal, stainless steel) to asbestos non-metallic materials such as metal wrapped package pads made; there is a thin strip asbestos from wound together with the spiral wound gasket. Ordinary rubber pads for temperature lower than 120 ℃ occasions; asbestos rubber gasket suitable for water vapor at temperatures below 450 ℃, for the oil temperature is below 350 ℃, the pressure is lower than 5MPa occasion, for the general corrosion medium, is the most commonly used acid. In the high-pressure equipment and pipelines, the use of copper, aluminum, 10 steel, stainless steel or other type of lens-shaped metal gasket. High-pressure gasket sealing surface contacts with a very narrow width (line contact), with the gasket sealing surface finish higher processing.
Forged flange sub-thread (thread T), flange and welding flange. Low-voltage wire of small diameter access flange, high pressure and low pressure are the use of large-diameter welded flange, flange pressure of the thickness and diameter and the number of connecting bolts are different.
