There are two types of seamless steel pipes: hot rolled seamless steel pipe and cold rolled seamless steel pipe . Are you confused about which seamless steel pipe to choose? Next, follow the editor and let us have an in-depth understanding of seamless steel tubes.
The difference between hot rolled seamless steel pipe and cold rolled seamless steel pipe:
1. Cold rolled seamless steel pipes are often of small diameter, while hot rolled seamless steel pipes are often of large diameter.
2. The precision of cold rolled seamless steel pipe is higher than that of hot rolled seamless steel pipe, and the price is also higher than that of hot rolled seamless steel pipe.
3. Hot rolled seamless pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
4. In addition to cold rolled steel pipes, low- and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold rolled seamless steel pipes also include carbon thin walled steel pipes, alloy thin walled steel pipes, and other steel pipes. Rusty thin-walled steel pipes, special-shaped steel pipes.
5. Advantages of hot rolled seamless pipes: It can destroy the casting structure of the steel ingot, refine the grains of the steel, and eliminate defects in the microstructure, thereby making the steel structure dense and improving the mechanical properties. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
When choosing seamless pipes, you need to make a judgment based on the specific application environment and requirements. When purchasing seamless pipes, you should also pay attention to the standards and quality of the pipes to ensure that the materials meet the requirements to improve the safety and reliability of the pipeline system. Hope this article can help you!
