The connection of cast flanged pipe fittings is to fix two pipes, pipe fittings or devices on the flanged pipe fitting plate respectively. The connection is made by tightening the two flanged fitting plates, flange gaskets and bolts together. Some fittings and devices used to have their own flanges, which is also how flanged fittings

Flange, also known as flange or flange plate, is the part connecting pipe end and pipe end and valve. Both sides of the flange are connected with the pipe end, and the flange itself has holes. Stainless steel flange is widely used in petroleum, chemical, nuclear power plant, food manufacturing, construction, shipbuilding, paper, medicine and other

Materials with low hardness and good toughness such as low carbon steel and aluminum alloy for stainless steel flange are characterized by low hardness and good toughness, difficult chip breaking during cutting, easy to generate chip accretion, which affects the processing surface quality. Therefore, the processing of stainless steel flange data often uses large front angle, high-speed

The nominal diameter of the vessel cylinder and the nominal diameter of the tube of the butt welding flange represent different specific sizes. Therefore, the same nominal diameter of the vessel stainless steel flange and the stainless steel butt welding flange, their sizes are also different, and they can not be substituted for each other. Usually, the

Flange is also called flange or flange. Flange is to make the pipe and pipe connected parts, connected to the end of the pipe. There are holes on the flange, and bolts make the two flanges tightly connected. The flange is sealed with gasket. The flange is divided into threaded connection (threaded connection) flange and

Chemical polishing of large stainless steel flanges is achieved by regular dissolution of flanged surfaces to smooth and smooth. During the chemical polishing process, the surface of iron and steel large stainless steel flange is continuously formed by passivation oxide film and oxide film, and the former is stronger than the latter. Due to the

Stainless steel flange itself is to link two pipes or some pipes effectively, fix them on a flange plate first, and then, with the relevant cushion, bolt tightly together, so that the effective connection can be completed, there are some stainless steel flanges, usually it is. They are a kind of disc-shaped parts, so the number

Medium carbon steel refers to carbon steel with carbon content of 0.25% – 0.60%, including 30, 35, 45, 50, 55 in high-quality carbon structure and zg230-450, zg270-500, ZG310-570 and zg340-640 in cast carbon steel. Because the carbon content of medium carbon steel is higher than that of low carbon steel, its weldability is worse than

In order to improve the corrosion resistance and decoration of large stainless steel flanges, it is necessary to polish the stainless steel surface. Now, there are three polishing and electrochemical polishing technologies, including mechanics, mechanics and chemistry. Because of the use of phosphoric acid and chromic anhydride in the existing stainless steel electropolishing liquid, many chromium (VI)
