Composition and production process of carbon steel

Composition and production process of carbon steel elbow

The composition of carbon steel elbow is relatively simple, and its composition is also relatively simple, can make people easy to understand and imagine.Most carbon steel elbows are processed by pressure processing, so that the processed carbon steel elbows produce plastic deformation.According to the elbow processing temperature is different, divided into cold processing and hot processing two.Carbon steel elbow hot processing process:After welding a polygonal cross-section multi-ring shell or fan-shaped shell with both ends blocked and filled with pressure medium, internal pressure is applied. Under the action of internal pressure, the cross-section changes from multilateral to round gradually and finally becomes a circular shell. According to the requirements, a circular shell can be cut into 4 90-degree elbows or 6 60-degree elbows.This process is suitable for making large elbows of any specification with the ratio of middle diameter to inner diameter of elbows greater than 1.5, and is an ideal way to manufacture carbon steel elbows.

Carbon steel elbow welding process in order to prevent the carbon steel elbow in the process of using cold crack, tubes preheating process before they go out, after the preheating treatment, can reduce zhongtong overheating effects, preheating can also improve plasticity, of elbow again after completion of welding, so can also reduces the residual stress,And different types of steel preheating temperature is different, but such steps are generally completed in the process of welding, we can according to the welding requirements, when the local preheating, the preheating temperature is adjusted.

Butt-welding elbow is a kind of long steel with a hollow section and no seams around it.The steel pipe has a hollow section, a large number of used for the transportation of fluid pipelines, such as oil, natural gas, gas, water and some solid materials pipelines.Compared with solid steel such as round pipe, steel pipe has the same bending and torsional strength and lighter weight. It is a kind of economic section steel. It is widely used in the manufacturing of components and mechanical parts, such as oil drill pipe, automobile drive shaft, automatic truck frame and steel scaffolding used in construction, etc.

Under the condition of equal circumference, the circle area is large, and the circle can transport more fluid butt-welding elbow. In addition, the ring section bears the internal or external radial pressure, and the force is more uniform. Therefore, the vast majority of steel pipes are round pipes.
