Features and maintenance methods of stainless steel flange

Stainless steel flange is a common type of flange. Because of its ability to withstand high pressure and the characteristics of stainless steel, it is deeply loved by people in the industry, so it is widely used. Let's take a look at the characteristics and precautions of stainless steel flange.

Flange is also called flange or flange. This is a pipe to pipe connecting part. Connect to the end of the pipe. There are holes in the flange, and bolts can be screwed to make the two flanges closely connected. The flange is sealed with a gasket. Fittings are fittings with flanges (flanges or adapters). It can be cast, threaded or welded. The flange connection consists of a pair of flanges, a washer and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the gasket is composed of a gasket, a gasket and several bolts and nuts.

The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the gasket consists of a gasket, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, deformation will occur when the specific pressure between the gasket surface and the upper surface reaches a certain value, and the uneven parts of the sealing surface and the upper part will be filled to ensure tight connection. Some pipe fittings and equipment have their own flanges, which also belong to flange connection. Stainless steel flange connection is an important connection method in pipeline construction. The flange is easy to use and can withstand large pressure. Flange connection is widely used in industrial pipelines.

In China, the pipe diameter is small, the pressure is low, and there is no flange connection. There are boilers and equipment everywhere. Generally speaking, the function of flange is to fix and seal the connection of pipe fittings.

Maintenance of stainless steel flange

The stainless steel flange integrates the flange body and the socket into an integrated structure, which avoids the leakage caused by the dislocation of the welded joint during welding. It has the advantages of simple structure, convenient use and good sealing performance.

The methods of stainless steel flange corrosion treatment include:

1. Clean with emery cloth and wire brush.

2. Use a tungsten steel shovel to remove large areas of rust.

3. Remove welding slag and other protrusions and various burrs with a file.

4. Use a scraper and wire brush to remove the rust at the edges and corners.

5. Clean with a clean rag or apply primer in time with a rag dipped in solvent.

6. Note that the ductile coating that has not failed can be retained. Roughen the surface of the old paint with emery cloth, polish the coating defects into axe shape, and paint directly after cleaning.
