A Comprehensive Analysis of the Production Structu

The industrial core position and classification of carbon steel elbows In modern chemical plants, the meandering pipes are as intricate as human blood vessels, and the key nodes that change the flow direction - carbon steel elbows - are the "joints" of the entire piping system. In 2022, the market size of pipe fittings in China exceeded 100 billion yuan, with carbon steel elbows accounting for more than 30%, which is sufficient to demonstrate their importance in the industrial field. The main function of carbon steel elbows is to change the flow direction of the medium in the pipeline. According to the angle, they can be classified into three major categories: 45°, 90° and 180°, among which 90° elbows are the most widely used. According to the curvature radius, long radius elbows (R=1.5D) have less fluid resistance and are suitable for applications with high transportation efficiency requirements; while short radius elbows (R=1.0D) have obvious advantages in installation environments with limited space. The different manufacturing processes result in the diverse structural features of carbon steel elbows. Hot-pushed elbows are formed through the heating and pushing process, featuring uniform wall thickness and low production cost;
