1. Overview
Carbon steel pipe is a common pipe with a wide range of applications. The number of carbon steel pipes usually includes the diameter, size, and wall thickness. What are the common numbers? Let's introduce them one by one.
Second, the common number
1. Carbon steel pipes below 4 inches are usually expressed in outer diameter, and the common specifications are 1/8 inch, 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch, 1.25 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, etc.
2. Carbon steel pipes of 4 inches and above are usually expressed in nominal diameter, and the common specifications are DN100, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN550, DN600, etc.
3. The wall thickness of carbon steel pipe is generally divided into three types: heavy wall, medium wall and light wall, among which the wall thickness of heavy wall is the largest, and the wall thickness of light wall is the smallest. Common wall thicknesses are SCH10, SCH20, SCH30, SCH40, SCH60, SCH80, SCH100, SCH120, SCH140, SCH160, etc.
3. Summary
The above are the common numbers of carbon steel pipes, including diameter size and wall thickness. In actual production and use, it is necessary to select the appropriate number according to specific needs. At the same time, when purchasing carbon steel pipes, we should also pay attention to whether the quality and specifications meet the requirements to ensure the safety and effect of use.
