A105Blind plateBLFlangeAlso known as blind flange, known as flange cover. There is no hole in the middle of the flange, used to seal the pipe plug. There are many types of sealing surfaces, including flat, convex, concave and convex, tongue and groove surface and ring connection surface.A105Blind plateBLThe flange production process is mainly divided into forging, casting and cutting. The shape and size of the cast flange blank are accurate, the processing amount is small, and the cost is low.A105Blind plateBLFlangeForging flange is generally lower than the casting flange carbon is not easy to rust, forging flow line is good, the microstructure is dense, the mechanical properties are better than the casting flange. The following is a brief introduction for everyoneA105Blind plateBLThe main performance advantages of flanges.

A105Blind plateBLFlangeThe performance advantages:

1It has excellent corrosion resistance and intergranular corrosion resistance. In stainless steel flat-welded flanges, there is a strong corrosion resistance in oxidizing acids such as nitric acid, whose concentration is less than percent of the boiling temperature.65.

2,A105Blind plateBLFlangeIt has good resistance to alkaline solutions and most organic and inorganic acids.

3,A105Blind plateBLFlangeHas excellent hot and cold forming performance. Can be processed to produce plates, tubes, lines, belts and other products, suitable for cold heading, deep drawing, deep drawing parts manufacturing.

4Better low temperature performance. In-180The 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.

5Good welding performance.A105Blind plateBLFlangeNo heat treatment is required before and after welding.
