What are the principles for the selection of seamless steel pipes?

Due to the different materials, processing methods, specific parameters and performance of seamless pipes (smls), their application fields will vary greatly. If you want to choose a suitable steel pipe, you must start from the actual demand, and pay attention to the basic selection method. The following introduces the basic selection principles of this material.

1. Temperature and pressure requirements

There are certain standards for the application environment of steel pipes. Generally speaking, ordinary seamless steel pipes are suitable for media with a temperature lower than 350°C and a pressure lower than 10MPa, such as oil, gasoline, etc., so pay attention to the specific conditions of the application environment and the medium. In some cases, if ordinary steel pipes cannot be used beyond this standard, other types of steel pipes may be selected.

2. Selection of special models

Some industries may have special requirements for steel pipes. For example, they may also require good impact and corrosion resistance in high temperature and high pressure environments. Then, the appropriate steel pipe should be selected according to the actual working conditions. For example, the steel pipes used in boilers now have special models, and not all steel pipes can be used in common.

3. Consider the price factor

Even for the same seamless pipe, due to the different channels we purchase, there are certain differences in quality, and naturally the price is also different. It is recommended to purchase according to our actual needs, contact the manufacturer directly, and enjoy the preferential quotation of the factory direct sales.

Tips: Seamless steel pipes (mild steel seamless pipes) made of mild steel are used for liquid piping. Seamless steel pipes made of medium carbon steel are used in mechanical parts such as stressed parts of automobiles and tractors. It is also used to manufacture structural parts and mechanical parts, which can improve the utilization rate of materials, simplify the manufacturing process and save materials.
