What is stainless steel flange?

Date:Aug 08, 2019
stainless steel flange is a part that connects the pipe to the pipe and is connected to the pipe end. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange threaded connection (wire connection) flange and welded flange.

Flanges are disc-shaped parts that are most common in pipeline engineering. The flanges are used in pairs and with the matching flanges on the valve. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed. The low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A gasket is placed between the two flanges and then bolted. Different pressure flanges have different thicknesses and use different bolts.

The main role of stainless steel flange:

1. Connect the pipeline and maintain the pipeline sealing performance;

2. It is convenient to replace a certain pipeline;

3. It is easy to open and inspect the pipeline;

4. It is convenient to close a certain pipeline.

Stainless steel flanges can be cast or they can be threaded or welded. The flange connection consists of a pair of flanges, a spacer and a number of bolts and nuts. The gasket is placed between the two flange sealing surfaces. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the unevenness on the sealing surface to make the joint tight.

Stainless steel flanged pipe fittings are repeatedly heated to precipitate carbides, reducing corrosion resistance and mechanical properties. Stainless steel flanges are suitably added with appropriate amounts of stability elements Ti, Nb, Mo, etc. to improve corrosion resistance and weldability. Stainless steel flanged pipe fittings have good corrosion resistance and oxidation resistance and are widely used in chemical, fertilizer, petroleum and medical machinery manufacturing.
