Casting flange has rough shape, accurate size, small processing volume, low cost, but casting defects (pores). The internal structure of the crack (inclusion) casting is not well shaped (if cut, the streamline is worse);
Forged flanges are generally less carbon-free than cast flanges. They are not easy to rust. They are streamlined, the structure is relatively compact, and the mechanical properties of the cast flange are superior;
Improper forging process can also cause large or uneven grains, hardening and cracking, and forging costs are higher than cast flanges.
Forgings bear higher shear and tensile forces than castings.
The advantage of casting is that more complex shapes can be manufactured at a lower cost;
Forged flanges in carbon steel flanges have a certain working principle. According to the production process and production process and the use of carbon steel flanges, there are certain working principles. The working principle is to use the insulation properties of carbon steel flange gaskets. High-strength carbon steel flange insulation, carbon steel flanges work in both electrical insulation flange factories. Mary iron and galvanized pipes are commonly used (saving iron) than steel, which is stronger than iron. Low carbon steel and low carbon steel, low carbon steel carbon content, easy to accept various processing such as forged carbon steel flange processing, welding and cutting, commonly used chains, rivets, bolts, shaft manufacturing, such as low carbon steel flanges Kilogram Yanshan belongs to low-carbon steel flange flange products. A forging process that bends a blank into an angle or shape. Second, purchase products: first determine whether the control medium is oil or water.
