Price called Shijiazhuang Shijiazhuang flange plate or flange flange prices.
The tube and pipe parts connected to each other, connected to the pipe end. Flange holes on the price of Shijiazhuang, Shijiazhuang flange bolts so that the two prices abuts. Shijiazhuang flange gaskets for sealing between the price. Shijiazhuang, pipe flange price (flanged pipe fittings) refers to the flange with the price of Shijiazhuang (flange or access plate) of the tube. It can be molded (Figure N), can also be threaded or welded form. Price Shijiazhuang flange connection (flange, joint) by a flange prices in Shijiazhuang, a gasket, and composed of a number of bolts and nuts. Shijiazhuang flange gasket on the price of two between the sealing surface, tighten the nut, the gasket surface pressure reaches a certain value deformation, and fill at the sealing surface uneven, so that does not leak tight connection. Shijiazhuang flange connection is a removable connection price. By the connected components can be divided into the container of Shijiazhuang, Shijiazhuang flange pipe flange price and the price. Divided by structural type, have an overall flange prices in Shijiazhuang, Shijiazhuang Looper Shijiazhuang flange threaded flange prices and price. Common overall prices flat welding flange Shijiazhuang Shijiazhuang Shijiazhuang flange welded flange prices and price. Flat welding flange Shijiazhuang price less rigid, the pressure p ≤ 4MPa for the occasion; butt Shijiazhuang Shijiazhuang flange neck flange price also known as high prices, greater rigidity, high pressure and temperature for the occasion. Shijiazhuang flange sealing surface of the price, 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. 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 a professional factory producing the required size, the material is asbestos rubber sheet, asbestos, polyethylene plate; also useful for sheet metal (tin, stainless steel) to asbestos made of non-metallic materials such as metal pack wrapped gasket; 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 the occasion, the general corrosion media, 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. High-pressure gasket and sealing surface of the contact width is very narrow (line contact), with the gasket sealing surface of the processing finish higher. |
