The cold bending process of carbon steel elbow pip

The cold bending process of carbon steel elbow pipe fittings is briefly introduced  

The cold bending performance of carbon steel elbow is an index to measure the crack resistance of steel when plastic deformation occurs during bending at room temperature.  In addition, the cold bending test can also detect the grain crystallization and distribution of non-metallic inclusions in the elbow of carbon steel, which is an index to judge the metallurgical quality of steel.  The cold bending performance of carbon steel elbow was determined by cold bending test  

In the test process, according to the grade of the sample, thickness and national standard bending center diameter, in the test machine on the standard sample of the middle of the load, so that the bending.  The bending Angle is 180 degrees.  After the test, according to the sample surface or side crack or stratification to judge the cold bending performance.  In the design of carbon steel elbows, the steel used for welding bearing structures and important non-welded bearing structures shall be qualified for cold bending tests.  

The above is the cold push bending process of carbon steel elbow that our company briefly introduces for customers. We hope it can help each customer who needs cold bending.  

The company mainly produces various types and materials of carbon steel elbow pipe fittings in the production of customized production process.  Welcome the customer consultation order!
