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

Flange is also called flange or flange. 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. Flange is a disc-shaped part, the most common in pipeline engineering, flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines.

The company mainly produces forged carbon steel flanges: flat flanges, sliding flanges, slotted flanges, galvanized flanges, square flanges and other special-shaped flanges
Whether the ordinary carbon steel flange has anti-corrosion function
The shape and size of ordinary carbon steel flanges are accurate, the processing volume is small, and the cost is low. However, the cast flange will have holes, cracks and impurities, and the cast internal structure is poor. The advantage is that it can have more complex shapes and is less expensive to produce.
The carbon content of ordinary carbon steel flanges is lower than that of cast flanges, so it is not easy to rust and has a dense structure. It can withstand shear and tensile forces better than forged flanges and has better mechanical properties.
Ordinary carbon steel flanges and cast flanges are difficult to distinguish from appearance alone. There are several methods for your reference:
The first is the price comparison. Flanges on the market are cheap to cast, then cast and forged, more expensive than pure forging.
The second is to perform a destructive test to separate the flanges. Castings have trachoma, but pure forgings do not. Cast and forged flanges sometimes have cracks.
The third is from the perspective of flange tolerance and surface finish, cast flanges usually have a negative tolerance of 1-5mm, irregular edge chamfers, no burrs in the holes, and forged flanges have smaller tolerances.
The fourth is weighing. A cast flange will be lighter than a forged flange for the same size flange.
When purchasing carbon steel flanges, they should be selected according to the usage environment. Not just cheap, but premised on them. Flanges, also known as flanges, can be divided into carbon steel flanges, stainless steel flanges and alloy steel flanges according to their materials.
Carbon steel flanges are flanges that contain carbon steel. According to the content of various trace elements, they can be divided into A105 material, Q235 material, 16MN material, 20# material, etc., and can be divided into forged flanges according to the production process. Cast flanges, mid-plate rolling and mid-plate cutting. Among them, the forged flanges are of good quality and then rolled and cast. Since carbon steel flanges are not corrosion resistant, the main corrosion protection treatments include oiling, painting and galvanizing.
