A105 blind BL flange, also known as blind flange, is called flange cover. The flange without hole in the middle is used to seal the pipe plug. There are many types of sealing surfaces, including flat, convex, concave convex, grooved and ring connecting surfaces. The production process of A105 blind BL flange is mainly divided into forging, casting and cutting. The casting flange blank has the advantages of accurate shape and size, small processing capacity and low cost. A105 blind BL flange forged flange generally has lower carbon content than cast flange, is not easy to rust, has good forging flow line, dense microstructure and better mechanical properties than cast flange. Here is a brief introduction to the main performance advantages of A105 blind BL flange.
Performance advantages of A105 blind BL flange:
1. It has excellent corrosion resistance and intergranular corrosion resistance. In stainless steel flat welding flange, the concentration of oxidizing acid with strong corrosion resistance such as nitric acid is 65% lower than the boiling point temperature.
2. A105 blind BL flange has good resistance to alkaline solution and most organic and inorganic acid corrosion.
3. A105 blind BL flange has excellent cold and hot forming performance. It can process and produce various products such as plates, tubes, wires and belts, and is suitable for manufacturing cold heading, deep drawing and deep drawing parts.
4. Better low temperature performance. At -180, the strength, elongation and shrinkage of the profile are very good. Because there is no ductile brittle transition temperature, it is usually used at low temperature.
5. Good welding performance. A105 blind BL flange does not need heat treatment before and after welding.
