There are various types of sealing surfaces available for carbon steel blind flanges, including flat, raised, recessed/raised, tongue-and-groove, and ring joint faces. The choice depends on the specific circumstances.The purpose of carbon steel blind flanges is to completely isolate the production medium, preventing it from leaking out due to incomplete closure of the cut-off valve. They are commonly used at the ends of equipment connections, before and after cut-off valves, or between two flanges.When using carbon steel blind flanges, attention should be paid to their maintenance and upkeep.

The main production processes are mainly divided into four types: forging, casting, cutting and rolling.The cast flange has accurate rough shape and size, small processing volume, and low cost, but it has casting defects (pores, cracks, inclusions); the internal structure of the casting has poor streamlined structure (if it is a cutting part, the streamlined shape is even worse);Forged flanges have low carbon content and are generally less likely to rust than cast flanges.

Loose-jacketed flanges are commonly known as loose-jacketed flanges, partial welding ring loose-jacketed flanges, flanges flanges and butt welding loose-jacketed flanges. It is often used when the medium temperature and pressure are not high and the medium is highly corrosive. When the medium is corrosive, the part of the flange in contact with the medium (flanged nipple) is a corrosion-resistant high-grade material, such as stainless steel and other materials, and the external use of low-grade materials such as carbon steel materials to clamp it to achieve sealing.

blind flange (blind flange), also known as blind flange, real name blind plate. It is a connection form of flange. It's basically a flange without a hole in the middle. One of its functions is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. In terms of sealing effect, it has the same effect as the head and the tube cap. However, there is no way to disassemble the head, and the flange blind plate is fixed with bolts, which is very convenient to disassemble.

Carbon steel flanges are precise in shape and size, with low machining and low cost. However, cast flanges will have holes, cracks and impurities, and the internal structure of the casting is poor. The advantage is that it can have more complex shapes and be produced at low cost. Plain carbon steel flanges are less susceptible to rust and have a denser structure because they have a lower carbon content than cast flanges. They can withstand shear and tensile forces better and have better mechanical properties than forged flanges.
Flange is a disk-shaped part, z is common in pipeline engineering, flanges are used in pairs. In pipeline engineering, the flange is mainly used for pipeline connection. In the pipeline that needs to be connected, a variety of installation of a piece of flange, low-pressure pipeline can use silk flange, more than 4 kilograms of pressure use welding flange. The gasket is added between the two pieces of flanges, and then tightened with bolts.
Carbon steel flange in accordance with national standards require the size, tolerance range and other production of the flange, the difference between the flange is not produced according to standard sizes also known as the second standard flange (some people call non-standard flange is incorrect), usually some unscrupulous businessmen will reduce the thickness of the flange, the outer diameter of the two dimensions to achieve the purpose of saving materials, and the use of scrap steel or steel processing flange of the edge material.Usually this steel is the chemical composition and mechanical
