Low-pressure vs ordinary carbon steel pipe: Application in the field of heating
Characteristics of carbon steel pipes vs low-pressure carbon steel pipes
1. The wall thickness of low-pressure carbon steel pipes is thin, generally below 5mm;
2. The diameter of low-pressure carbon steel pipes is relatively small, generally between 10mm and 108mm;
3. The compressive strength of low-pressure carbon steel pipes is lower than that of ordinary carbon steel pipes, usually below 2.49MPa;
4. Low-pressure carbon steel pipes have good weldability and processing performance, suitable for on-site installation and maintenance.
Advantages of low-pressure carbon steel pipes in the field of heating
1. Small heat loss: low-pressure carbon steel pipes have thin walls, fast heat transfer, and less heat loss.
2. Relatively low material cost: usually lower cost than easy-to-process high-pressure pipes (such as steel-plastic composite pipes, etc.).
3. Convenient construction: low-pressure carbon steel pipes can be welded and easily processed and assembled on site. And relatively few assembly processes are usually required.
Differences in the application of low-pressure carbon steel pipes in the field of heating
1. Different scope of use: low-pressure carbon steel pipes are generally used in buildings, community tap water, heating and other occasions with pressures below 2.5MPa, while ordinary carbon steel pipes are used in high-pressure and large-diameter occasions.
2. Different corrosion resistance: low-pressure carbon steel pipes and ordinary carbon steel pipes have different corrosion resistance. In heating occasions, low-pressure carbon steel pipes are easily corroded due to the presence of oxygen, moisture and chloride ions in the medium water. Ordinary carbon steel pipes improve their corrosion resistance through external painting and other methods, so they are more suitable for occasions with higher demands.
3. Different maintenance costs: Since low-pressure carbon steel pipes have thin walls and are easily subject to external pressure and damage, they require more frequent inspection and maintenance. Ordinary carbon steel pipes have lower maintenance costs in the heating field due to their materials and characteristics.
Summary
Low-pressure carbon steel pipes have certain advantages in the heating field, but compared with ordinary carbon steel pipes, they also have some limitations and application differences. Therefore, in actual applications, different materials need to be selected according to specific occasions and needs.
