What is wenzhou flange (flang
High pressure flange (flange JBZQ sae 4187-4187
Also called flange or flange.
Wenzhou flange connection in the pipe. Hole in the flange, pipe and pipe connected parts. Two flange bolt that even tight. The flange gasket seal. Flange pipe fittings (flang pipe flange (flange or flange) fit to pipe fittings. Wenzhou flange can be made from a cast filled by any (figure) can also be composed of threaded connection or welding. Flange connection (flang be by a flange, a gasket and a number of bolt and nut. Gasket in between the flange sealing surface, tighten the nut, the gasket on the surface of a pressure deformation after reaching a certain value, fill and seal surface uneven, to join together don't leak. Flange connection is a detachable connection.
Wenzhou flange, in accordance with the flange and pipe flange connection components can be divided into the container. According to the structure, have integral flange, flange and threaded flange. Common integral flange are flat welding flange and butt welding flange. Flat welding flange of the poor rigidity, suitable for pressure p 4 mpa or less; Butt welding flange is also called the high neck flange, large rigidity, suitable for the occasion of high pressure and temperature. There are three kinds of flange sealing surface model: planar seal face, is suitable for the occasion of pressure is not high, medium non-toxic; Concave-convex sealing surface, suitable for pressure slightly higher occasion; Mortise sealing surface, suitable for flammable, explosive, toxic medium and high pressure situation. Gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials. Most of the gasket from nonmetal board cut down or by professional factory size produced by the regulation, wenzhou flange its material such as asbestos rubber sheet, asbestos board, polyethylene plate; Also useful sheet metal (tin, stainless steel) will be made of asbestos etc. Nonmetal material wrapped metal package cushion; Another with steelskin belt with asbestos tape winding of spiral wound gasket. Ordinary rubber gasket is suitable for the occasion of temperature below 120 ℃; Asbestos rubber gasket suitable for vapor temperature below 450 ℃, the oil temperature is below 350 ℃, pressure is lower than 5 mpa, for general corrosive medium, the most commonly used acid asbestos board. High pressure equipment and pipeline, using 10 copper, aluminum, steel, stainless steel type lens or other shaped metal gasket. High pressure washer and sealing surface contact width is very narrow (line contact) with gasket sealing surface processing finish higher.
