How to distinguish ordinary carbon steel flanges
The shape and size of ordinary carbon steel flanges are accurate, the processing volume is small, and the cost is low. However, the casting flange will have holes, cracks and impurities, and the internal structure of the casting is poor. It has the advantage that it can have more complex shapes and is low cost to produce.

Flange is also called flange plate or flange plate. The part that connects the pipe to the pipe, connected to the pipe end. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanged fittings refer to fittings with flanges (flanges or pans). It can be cast (not shown in the figure), or it can be threaded or welded.

What is the difference between carbon steel flanges and stainless steel flanges?
Flange is a disc-shaped part, which is the most common in pipeline engineering, and flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a gasket between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses and use different bolts.

The technical advantages of carbon steel flanges!
Usually this kind of steel is waste material with substandard chemical composition and mechanical properties. What’s more, the flanges are produced by private steelmaking in black steel plants. The steelmaking technology used in this private steelmaking is outdated and cannot guarantee the mechanical properties and welding properties.

How to determine the quality of carbon steel flanges?
The shape and size of carbon steel flanges are accurate, the processing volume is small, and the cost is low. However, the casting flange will have holes, cracks and impurities, and the internal structure of the casting is poor. It has the advantage that it can have more complex shapes and is low cost to produce. Because the carbon content of ordinary carbon steel flanges is lower than that of cast flanges, it is not easy to rust and has a dense structure.

The connection method of the national standard flange!
Another meaning of the national standard flange is: the flange plate produced according to the size and tolerance range required by the national standard is different from the flange sheet produced not according to the standard size, which is also called the second standard flange (some people call it non-standard flange). is incorrect), usually some unscrupulous merchants will reduce the flange thickness and outer diameter to save materials, and use scrap steel or scrap steel to process flanges, usually this steel is chemical composition and mechanical Scrap whose performance does not meet the standard, and even the use of private steelmaking in black steel plants to produce flanges.
