A 90 degree elbow is mainly used as a connecting fitting in pipeline installation, for connecting at pipe bends. Connect two pipes with the same or different nominal diameters to make a 90 degree turn in the pipeline. 90 degree elbows are mostly stamped and welded elbows, which are made of the same material as the pipe material and stamped into half circular elbows using a stamping die. Then, the two half circular elbows are assembled and welded into shape. Due to the different welding standards for various types of pipelines, semi-finished products are usually fixed by spot welding according to the assembly before leaving the factory. On site construction is carried out according to the welding grade of the pipeline, therefore, it is also known as two half welded elbows.
The forming process of stamping elbows is complex and requires welding according to different materials and applications, gradually forming under a certain pressure. The forming of stamping elbows needs to follow a certain process and strictly follow the corresponding process, otherwise the produced stamping elbows will have quality problems. As needed, a circular ring shell can be cut into 4 90 degree elbows, 6 60 degree elbows, or other sizes of elbows.
The production efficiency of stamping processing is high, and the operation is convenient, making it easy to achieve mechanization and automation. This is because stamping relies on stamping dies and stamping equipment to complete the processing. The travel times of ordinary press machines can reach dozens of times per minute, and high-speed pressure can reach hundreds or even thousands of times per minute. Moreover, each stamping stroke may result in a stamping part. So it has strong impact resistance.
Another point that must be mentioned is that the service life of a stamped 90 degree elbow is very long, and it is said to reach over 50 years. Due to its rated temperature and pressure, it not only emits radiation and ultraviolet rays, but also ensures that the product never fades. Stamping a 90 degree elbow has many advantages in addition to high production efficiency, such as the absence of chips and debris, and the ability to process parts with a large size range. Therefore, the stamping process has become a highly favored 90 degree elbow production process by Mengcun elbow manufacturers!
