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)

The basic process of carbon steel elbow forming is: first, weld a polygonal ring shell or a polygonal fan-shaped shell with both ends closed. After the internal pressure is filled with pressure medium, the cross-section gradually changes from polygon to circle and finally becomes a circular ring shell. Other names: 90 ° elbow, right angle bend, Aier

How to use flanges? Can flange be welded? With the continuous improvement of the authoritative way of selecting flanges, it is gradually convenient to know the price of the whole flange and how to weld the flange. We know that the comparison of the two ways of butt welding fittings and flat welding flange has been gradually

Stainless steel flange is also called flange or flange. The flange is the part that makes the pipe and the pipe connect with each other, and is connected to the pipe end. There are holes in the flange, and the bolts make the two flanges tightly connected. The stainless steel flange connection is easy to use

Production processes are mainly divided into forging, casting, cutting and rolling. The cast flange has accurate blank shape and size, small processing capacity and low cost, but there are casting defects (pores, cracks and inclusions); The internal organization streamline of the casting is poor (if it is a cutting part, the streamline is even worse);
