A bend is a type of pipe fitting that is typically used at the curved section of a pipeline to change the direction of fluid flow. Its product description includes the type of connection, bend angle, bend radius, and connection size. Common materials for bends include carbon steel, stainless steel, cast iron, brass, copper-nickel alloy, and the specific choice of material depends on the working environment and requirements of the pipeline. Common types of bends include 15, 30, 45, 60, and 90-degree bends, as well as special types such as three-way and four-way bends. The size and type of bend should be selected based on factors such as pipe diameter, wall thickness, and flow rate to ensure smooth fluid flow and proper operation of the pipeline system.

The characteristics of forged bends mainly include:

1. High strength: Forged bends are made by hammering and extruding metal materials at high temperatures and pressures to form the desired shape. This manufacturing method can make the bends have higher strength and toughness, allowing them to perform better in high-pressure, high-temperature, and other harsh working environments.

2. Excellent sealing performance: The inside and outside of forged bends are processed by hammering and extrusion, making the surface smoother and reducing the risk of defects and pores, thereby improving their sealing performance and reducing the risk of leakage.

3. Good plasticity: During the manufacturing process of forged bends, metal materials undergo plastic deformation at high temperatures and pressures, making them more malleable and allowing for more precise processing to meet different engineering requirements.

4. High precision: Since forged bends are manufactured at high temperatures and pressures, their shapes are more precise and their sizes are more stable, making them more accurate than other manufacturing methods.

5. Corrosion resistance: Forged bends can be made from various materials such as carbon steel, stainless steel, and alloy steel, which have good corrosion resistance and can be used for long periods in harsh working environments, reducing maintenance and replacement costs.
