A 90-degree bend is a common pipe fitting primarily used to change the pipeline direction, with an exact 90-degree angle. It is widely applied in various industrial piping systems, including oil, natural gas, chemical, power generation, and water conservancy sectors.
The manufacturing process of 90-degree bends involves multiple precision steps. High-quality steel is selected as raw material to ensure its chemical composition and mechanical properties meet standards. The bend shape is then formed through hot pressing or cold bending processes - hot pressing is suitable for thick-walled elbows to enhance material plasticity, while cold bending is ideal for thin-walled products to prevent material oxidation. Subsequent steps include welding and grinding to ensure smooth, defect-free interfaces. Heat treatment is applied to eliminate internal stress, and non-destructive testing (such as X-ray or ultrasonic inspection) verifies internal quality. The entire process strictly adheres to API standards, ensuring each elbow's reliability and durability.
