How to choose hot rolled pipe?
First, we need to understand the types of hot rolled pipes. Hot-rolled pipes can be mainly divided into seamless hot-rolled pipes (seamless pipe) and welded hot-rolled pipes (welded pipe). Seamless hot-rolled pipes are made by perforating the blank, heating it, and rolling it in multiple passes. It has excellent mechanical properties and no internal or external surface defects. Welded hot-rolled pipes are made by bending steel plates into circles and then welding them together to form pipes. For different usage scenarios, we can choose suitable hot-rolled pipes according to actual needs.
Secondly, we need to consider the material of the hot-rolled pipe. The material of hot-rolled pipe is directly related to its corrosion resistance, high temperature resistance and strength. Common hot-rolled pipe materials include carbon steel, alloy steel and stainless steel. Carbon steel hot-rolled pipes are cheap and easy to process, and are suitable for general low-pressure fluid transportation and mechanical structure purposes. Alloy steel hot-rolled pipes have better high temperature resistance and corrosion resistance, and are suitable for work in high temperature and corrosive environments. Stainless steel hot-rolled pipes have good corrosion resistance and aesthetics, and are suitable for scenes with higher requirements.
In addition, we also need to pay attention to the size and specification of hot-rolled pipes. The size and specifications of hot-rolled pipes are directly related to the stability and safety of their use. When selecting, the appropriate outer diameter, wall thickness and length should be selected based on specific scenarios and needs. At the same time, attention should also be paid to the connection method of hot-rolled pipes, which are usually connected by welding, threads, and clamps. Ensure that the connection of hot-rolled pipes is firm and reliable to avoid accidents such as leakage.
Finally, we need to consider the production process and quality of hot-rolled pipes. High-quality hot-rolled pipes should have standardized production processes to ensure that the pipe surface is smooth and free of creases, cracks, defects and other problems. In addition, attention should also be paid to the manufacturer and brand reputation of hot-rolled pipes. Choosing manufacturers and brands with good reputation and professional production capabilities can ensure the quality and after-sales service of hot-rolled pipes.
To sum up, the selection of hot-rolled pipes needs to consider many factors, including type, material, size, connection method and production quality. When choosing, you should make comprehensive considerations based on specific needs and usage scenarios, and choose manufacturers and brands with good reputation and professional capabilities. I hope this article can provide you with some help when choosing hot-rolled pipes, help you choose suitable hot-rolled pipes, and improve work efficiency and safety.
