Product Description

High Pressure 304 304L 316 316L 904 Forged Pipe Fittings Stainless Flanges High Pressure Pipe Flanges

Forged flange is a product with the best mechanical properties among flange products. Its raw material is generally a tube blank, which is then cut and then continuously beaten to eliminate segregation, looseness and other defects in the ingot. The price and mechanical properties are one grade higher than ordinary cast flanges. The flange is the part that connects the pipe with the pipe and the valve, and is connected to the pipe end; it is also used for the flange on the inlet and outlet of the equipment, which is used for the connection between the two equipment. at the pipe end. It is an accessory product of the pipeline. The main materials of forged flanges are carbon steel, alloy steel and stainless steel. The main standards are national standard, electrical standard, American standard, German standard, Japanese standard and so on. The main anti-corrosion treatments are oiling and galvanizing. Forged flanges have good pressure and temperature resistance, and are generally suitable for high-pressure and high-temperature working environments.

The forging process generally consists of the following procedures, namely, selecting high-quality steel billets, blanking, heating, forming, and cooling after forging. Forging process methods include free forging, die forging and fetal membrane forging. During production, different forging methods are selected according to the quality of the forgings and the number of production batches.

Free forging has low productivity and large machining allowance, but the tool is simple and versatile, so it is widely used for forging single-piece and small-batch forgings with simple shapes. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, etc., which are respectively suitable for the production of small, medium and large forgings. Die forging has high productivity, simple operation, and easy mechanization and automation. Die forgings have high dimensional accuracy, small machining allowance, and more reasonable distribution of fiber structure, which can further improve the service life of parts.

Forged flanges generally have lower carbon content than cast flanges and are not easy to rust, the forgings are streamlined, the structure is relatively dense, and the mechanical properties are better than those of cast flanges;

Improper forging process will also cause large or uneven grains, hardening cracks, and forging costs are higher than casting flanges.

Forgings can withstand higher shear and tensile forces than castings.

The advantage of casting is that it can make a more complex shape and the cost is relatively low;

The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the casting;
