The main defect of carbon steel elbow

Carbon steel elbow is an important pipe connection, widely used in petroleum, chemical, gas and other industries. However, there are also some defects in the use of carbon steel elbow. The following will expand the main defects of carbon steel elbow, in order to help readers.

1. Poor corrosion performance

Carbon steel elbows are prone to corrosion under the action of wet, acidic, alkaline and corrosive media, resulting in pipeline leakage, fracture and other problems. Especially in seawater, oil and other corrosive media, the corrosion rate of carbon steel elbow is more obvious.

2. Poor heat resistance

The heat resistance of carbon steel elbow is poor, and there will be deformation, crack and poor plasticity under the action of high temperature for a long time. Therefore, under high temperature, high pressure and other conditions, the service life of carbon steel elbow is short.

3. Poor toughness
