Carbon steel of various compositions for cast flanges

Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast looseness caused by metal smelting. , Optimize the microstructure, and because of the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of related machinery with high load and severe working conditions, forgings are mostly used except for simpler shapes that can be rolled, profiles or welded parts. The following introduces rolled flanges. The process of rolling flanges by cutting strips from the middle plate and then rolling them into a circle is called rolling. It is mostly used in the production of some large flanges. After the rolling is successful, it is welded, then flattened, and then carried out. Process processing of water lines and bolt holes.

The anti-corrosion treatment of cast flange is oiled and galvanized
The main anti-corrosion treatments for forged flanges include oiling and galvanizing. Forged flanges are the product with the best mechanical properties in flange products. Its raw material is generally tube blanks, which are then cut and beaten continuously to eliminate Defects such as segregation and porosity in the steel ingot. The price and mechanical properties are higher than ordinary cast flanges. The stainless steel flange is a part that connects the pipe to the pipe and the valve, and is connected to the pipe end; it is also a flange used at the inlet and outlet of the equipment. The connection between two equipment is a part to connect the pipe to the pipe. Connect to the pipe end. It is an accessory product for pipelines. 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 better pressure and temperature resistance, and are generally suitable for high-pressure and high-temperature working environments.
