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.

American standard carbon steel flange neck flat welding flange SO flange ensures qualityIn pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, install a flange. Low-pressure pipelines can use wire flanges, and welding flanges can be used with pressures above 4 kg. Add a sealing point between the two flanges and tighten them with bolts. Flanges for different pressures have different thicknesses and use different bolts.

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.

Flat welded flange with neck belongs to the national standard flange system. It is one of the manifestations of the national standard flange (also known as GB flange), and is one of the commonly used flanges on equipment or pipelines. The neck height of flat welded flange with neck is low, which improves the stiffness and bearing capacity of the flange.

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.

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 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.
