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.

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.

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 full name of die forging is die forging. The heated blank is placed in a forging die fixed on the die forging equipment and is forged into shape. The basic processes of die forging: blanking, heating, pre-forging, final forging, skin punching, trimming, tempering, and shot blasting. Commonly used processes include upsetting, lengthening, bending, punching, and forming. Commonly used die forging equipment: die forging hammer, hot die forging press, flat forging machine and friction press, etc.

The forging process generally consists of the following steps, namely, selecting high-quality steel billets for blanking, heating, forming, and cooling after forging. The forging process methods include free forging, die forging and membrane forging. During production, different forging methods are selected according to the quality of the forgings and the size of the production batch.Free forging has low productivity and large machining allowance, but the tools are simple and versatile, so it is widely used for forging single pieces with simple shapes and small batch production of forgings.

During free forging, the shape of the forging is gradually forged from the blank through some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.Upsetting. Upsetting is an operation process of forging the original blank along the axial direction to reduce its height and increase its cross-section. This process is commonly used for forging gear blanks and other disc-shaped forgings. Upsetting is divided into two types: total upsetting and partial forging. Pull out.

Flat welding flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flat welded flanges are divided into threaded connection (wire connection) flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and number are different.

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.
